Mech Pilot (5e Class)
The Mech Pilot
Introduction
The battle seems lost. The body of your party´s fighter dangles from a spear held by a hatefully laughing orc, meanwhile your sorcerer, that ran out of spells a while ago, screams in panic while being chased by three blood-hungry mercenaries, stabbing him with their daggers and cackling hysterically. And you? You lay in the puddle of what's left from your party. You are bleeding profusely while slowly losing consciousness. The only thing you can see now, is an army, walking towards you in perfect synchronization, eagerly awaiting to finally fulfill their duty and collect their toll...
Suddenly, from the corner of your eye, you see a four-legged beast, completely made of metal appear from thin air, firing five extremely fast objects, leaving a huge cloud of smoke. A fraction of a second later, hundreds of soldiers are sent flying into the air, carried by an enormous shockwave that shakes you to the bone.
As you look towards the rest of you party, you see the three mercenaries getting skewered by an enormous humanoid made of steel. It tackles them over the battlefield with abnormal speed while a tiny goblin, sitting where this thing should have its chest and neck, cackles even more insanely and happily than his victims did before. With a crunch the mercenaries are smashed against a nearby wall.
You turn around to see the battlefield engulfed in flames while the first metal beast unleashes a nova of deafeningly loud shots, mowing down dozens of soldiers. The metal humanoid charges into the flames and disappears, just to erupt again in the middle of that army, flinging around soldiers like leaves in the wind. Seconds later, it becomes silent. The battlefield has turned into an enormous bloodbath and some leftover stragglers run away in horror while one after another is taken out by a precise shot to their heads.
You look over to your sorcerer, that still stares at the smashed remains of these mercenaries. You whisper: "Are we the ones being saved?"
The humanoid walks between you, blocking your sight at the sorcerer, while the first metal construct bows down to you, loading the next shot with a snaring sound....
Description
The Mech Pilot class revolves around a pilot steering an automated armor suit. This armor suit protects you and grants you access to unique and powerful abilities.
When you start the game, you get your own personal mech. Over the course of the game it can be modified by adding modules.
Creating a Mech Pilot
When creating a Mech Pilot, think about the way your character got their mech. Try to think of the reasons why this mech was needed in the first place. Did someone teach you engineering skills or did you learn everything by yourself? What did you do before you created a huge war machine? And what will you do if you find yourself in a situation without your mech?

The Mech
At 1st level you have your own self-built mech. A monster stat block is provided at the end of this supplement to represent your mech, with additional features and traits providing a basis for the features of this class. The stat block is designed to be used with the features provided here, and much of the information here is repeated in the stat block in the form of special features. Some information is shown twice, once in this feature and again in the sample stat block, but is not intended to be applied twice, such as how the mech interacts with different types of damage. Your mech has the following modifications to its traits:
Ability Scores. The mech uses your Intelligence for its Strength, your Wisdom for its Dexterity, and your Charisma for its Constitution. The mech does not have its own mental ability scores. If your Intelligence, Wisdom, or Charisma scores should change, the mech’s corresponding ability scores do not change until you spend an hour modifying it.
Size. The mech is one size larger than you are. It weighs 16 times as much as you, is twice your height, and is twice as wide and thick as you are. The space inside of it is large enough to house a creature your size or smaller as well as the gear it is wearing or carrying (within reason). Creatures and objects inside the mech don’t count towards encumbrance. Due to its size, material, and other factors, the mech has disadvantage on Dexterity (Stealth) checks.
AC. The mech’s AC is equal to 9 + the mech’s Strength modifier + the mech's Constitution modifier.
Hit Points. The mech has hit points equal to 6 + its Constitution modifier for each level you have in this class, plus an additional 4 when you first become a mech pilot. A 5th level mech pilot with a Charisma of 14 would have a mech with 44 hit points. The mech cannot regain hit points normally. If you would roll a hit die to regain hit points during a short rest, you may instead add your Intelligence modifier to the roll and apply the result to your mech’s hit points rather than your own. Spells and magical effects that repair objects can also provide limited healing for the mech, as described in the stat block.
Impact Damage: Acid, bludgeoning, force, piercing, and slashing damage is dealt to the mech as normal.
Irrelevant Damage: The mech is immune to poison and psychic damage.
Buffered Damage: Cold, fire, lightning, necrotic, radiant, and thunder damage is halved against the mech while a creature is inside it, and each creature in the mech takes the same damage. These damage calculations are applied before vulnerability, resistance, and immunity.
If the mech is reduced to 0 hit points, the mech falls prone and deactivates, and excess damage is dealt to the creature piloting it. The mech cannot be reactivated until it regains at least half of its hit points, and the creature piloting it is prone until it leaves the mech. The mech is considered unconscious while deactivated, whatever the reason for it being deactivated.
Speed. The mech’s movement speed is entirely dependent on its size and how well its pilot can control it. The mech’s base movement speed is calculated as follows: For each size it is above Tiny, its speed is increased by 5 feet. Its speed increases by another 5 feet x the pilot’s Dexterity modifier (a minimum of 5 ft). Additionally, the mech cannot swim, crawl, or jump, and it must use its full speed to stand up from prone.
Actions and Combat. The mech has two arms, each of which can be equipped with an integrated weapon. Choose one nonmagical melee one-handed weapon you are proficient with for each arm. The Integrated Weapon attack action uses that weapon for the attack’s stats, which then gains the Light property and loses the versatile property. If the integrated weapon has the Thrown property, the mech can store up to three copies of that weapon in the chosen arm.
Arm Cannon. The ranged weapons in both of your mech’s arms have the Ammunition (range 60/180), Heavy, and Loading properties, deal a base of 1d8 piercing damage, and they use the mech’s Strength modifier for attack and damage rolls. Each arm can store up to 3 pieces of ammunition for these weapons, which replenish when the mech finishes a short or long rest. If the mech fires either Arm Cannon while not anchored, it must succeed on a Dexterity saving throw against a DC of 8 + your Intelligence modifier + your proficiency bonus or fall prone.
Hands. The mech also has a three-fingered claw hand for each arm that is typically used when not in combat. These hands can be used for clumsy or simple tasks, such as to grasp things or grapple targets, but cannot be used for anything complex or tasks that require finesse, such as picking a lock, turning book pages, holding cards, tying knots, holding weapons, etc.
The various types of things that make up a mech's arm are called "modes". Each arm of the mech can only have one mode equipped at a time. The mech must use a bonus action to change between these modes, but both arms can be changed with the same bonus action. The integrated weapon, the arm cannon, and the hands are all different modes. If the mech can change its arms into other things besides these three options, it takes a bonus action to do so, as described in this feature. Some modules that require a Right Arm or Left Arm slot, such as the Mining Drill utility module, add a new mode to the arm, while other modules, such as the Shock Bolt combat module, make use of an existing mode.
The mech cannot do anything unless it is activated and being piloted by another creature. The mech does not roll initiative and instead takes its turn whenever the creature piloting it takes a turn.
Attacks and Saving Throw DCs. The mech is considered proficient with all of its attacks and abilities, all of which use the mech’s Strength as the ability modifier. The mech uses your proficiency bonus in place of its own. If one of the mech's features forces any creature (including itself) to make a saving throw, the DC of that save is equal to 8 + the mech’s Strength modifier + your proficiency bonus.
Mech Destruction and Rebuilding. The mech can be irreparably destroyed in much the same way that a player character can die: from massive damage and failed death saves. The mech does not make death saving throws, but it can accumulate death saving throw failures. If the mech is at 0 hit points, any time it would receive damage equal to or greater than one third its maximum hit points in a single damage roll, it suffers 1 death saving throw failure. If it takes an amount of damage equal to or greater than its maximum hit points in a single damage roll, whether or not it's at 0 hit points, it is instantly destroyed. The mech keeps all death saving throw failures until it has at least half its maximum hit points again.
The mech can be rebuilt by salvaging the remaining components and collecting replacement parts, which can be costly in both time and money. It takes 8 hours to rebuild the mech + 1 hour for each module it is equipped with, and costs 100gp for each level you have in this class + 100gp for each module the mech is equipped with. You always have the choice of building a mech without any modules. If you build a mech without the full number of modules, you must spend the appropriate amount of time and gold to add the modules (except when adding modules from gaining levels in this class).
Building Additional Mechs. You can also build other mechs, which can then in turn be piloted by other creatures. However, any of your mechs that isn’t piloted by you has disadvantage on all ability checks, attack rolls, and saving throws, and everything has advantage on saving throws against the mech’s abilities, effects, and features. A creature piloting the mech can, as an action during its turn, attempt to succeed on an Intelligence check with a DC of 15 + half your mech pilot level (rounded down) to allow the mech to not have these penalties for next two turns. It costs 10 times as many gold pieces to build a mech from scratch, and it takes four times as long. There is no limit on how many mechs you can build.
Note: Much of this feature, while important to read, is statistical information that can easily be sorted in different areas of your character sheet. Ideally, you won’t actually have to write very much down in the Features and Traits section as it can all be distributed to other spaces in your character sheet or remembered.
Mech Specialization
Also at 1st level, you have a specific way of building your mechs, choosing from the Body Mech, the Enchanted Mech, and the Machine Mech. Your choice grants you features when you choose it at 1st level and again at 6th, 14th, and 20th level.
Modules
Starting at 2nd level, you can equip your mech with various types of modules, granting your mech new features and abilities. Your mech has one combat module from the list at the end of the class description. As you gain levels in this class, your mech gains more modules as shown in the Combat Modules and Utility Modules columns of the Mech Pilot table. When you gain a new module with this feature, it must be from the corresponding module list. Additionally, you can choose to change one of your mech’s modules for a different one instead of expending hit dice during a short rest, or instead of regaining your choice between hit points and hit dice during a long rest.
The mech cannot sustain infinite complexity, nor can the individual parts of it. Some modules modify specific portions of the mech, and the limit to how complex each portion of the mech can be is represented by a number of slots for that portion. The mech has 2 Body slots, 2 Right Arm slots, 2 Left Arm slots, 2 Leg slots, and 2 Pilot slots. If a module requires a slot, it consumes the chosen slot. If a module requires one of the mech's arm slots, the module is placed in the chosen arm and can only be used from that arm.
Ability Score Improvement
When you reach 4th level, and again at 8th, 12th, 16th and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.
Mechanical Understanding
By 5th level, your tinkering with your mech has given an innate understanding of machines and other constructs, allowing you to grasp the functions of unknown machines more easily. Whenever you make an Intelligence check relating to constructs, machines, or siege weaponry, you are considered proficient in the check, and you double your proficiency bonus for that check.
Universal Upgrade
At 7th level, choose one module from either module list. This module is your universal module and is applied to each mech you build. This module does not count against the total number of modules the mech may be equipped with, and it cannot be changed. This module also does not increase the cost of rebuilding mechs or when building new ones. Alternatively, you may choose a feat from the list of Feats in chapter 5 of the Player’s Handbook for your mechs to gain, if your DM allows it. The number of modules your mechs may have equipped in this way increases to two at 13th level and to three at 18th level.
Mech Fighting Style
At 9th level, you adopt a particular style of fighting with your mech as your specialty. Choose one of the following options. A mech benefits from this feature only while you pilot it.
- Automated Protection
When a creature within 30 feet of the mech that the mech can see attacks a target that is within 5 feet of the mech, the mech can impose disadvantage on the attack roll (no action required). The mech can’t do so again until the start of your next turn.
- Balanced Weapon Fighting
When the mech engages in two-weapon fighting, it can add its ability modifier to the damage of the second attack.
- Defensive Bulwark
The mech gains a +1 bonus to AC. The mech gains another +1 bonus to AC while anchored.
- Precision Aiming
The mech gains a +2 bonus to ranged attacks.
Piloting Instincts
At 10th level, you have enhanced instincts and reflexes from having piloted your mech for so long. While you are piloting your mech, the mech has advantage on Dexterity saving throws against effects you can see, and you also have advantage on Dexterity saving throws against effects you can see. You also have advantage on Initiative checks.
Excessive Force
Beginning at 11th level, your mech gets an upgrade to one of its core features. Choose one of the following options for your mech, which is incorporated into the mech’s relevant body part. The chosen option provides two passive effects and one activated ability. Once the mech uses one of this feature’s activated abilities, it can’t use that ability again until it finishes a short or long rest.
At 17th level, you can choose an additional option to incorporate into the mech, choosing a different part of the mech with the option. These options do not count towards the maximum number of modifications the body part can receive.
- Armament
Multiple weapons can be integrated into this arm, granting a wider variety of ways to fight. The arm can have up to three different weapons incorporated into it, but only one can be equipped at a time. The weapons can all be the same or different weapons. In addition, once during each of its turns the mech may switch between modes on that arm without using a bonus action.
As an action, the mech can temporarily equip all the incorporated weapons in this arm at once, making a melee weapon attack against a target within 5 feet of it. On a hit, the target takes the damage of each weapon, making separate damage rolls for each weapon and adding the mech’s Strength modifier to each damage roll. Roll this damage once for each attack the mech can make during an Attack action.
- Ballista
The mech’s arm is much thicker than before as it houses a larger supply of ammunition for that arm’s Arm Cannon, allowing the arm to hold up to 7 pieces of ammunition for the Arm Cannon weapon. The ranges of the Arm Cannon weapon on this arm are also increased by 60 feet each.
As an action while this arm’s Arm Cannon is equipped, the mech can fire three pieces of ammunition at once from this arm, making a ranged weapon attack against a target within 240/600 feet. On a hit, the target takes 8d8 + the mech’s Strength modifier piercing damage, or half as much damage on a miss. The mech cannot use that arm until the end of its next turn.
- Crushing Grip
The fingers on your mech’s hand are reinforced with extra-tough metal plating, of which there are now five. The mech has advantage on Strength (Athletics) checks made to grapple creatures with this hand, and this hand is now capable of finer interactions with objects, such as opening doors, wielding weapons without the finesse property, and picking up coins and other similarly-sized objects.
As an action while this arm’s hand is equipped, the mech makes a melee weapon attack against a target within 5 feet of it. On a hit, the target takes 5d8 + the mech’s Strength modifier bludgeoning damage and is grappled by this hand. The target is restrained while grappled in this way.
- Dual Purpose
The end of the mech’s arm is now capable of using two different modes at once. While using only one mode, the arm deals an additional die of damage with each of its attacks and modules, and the arm may have an additional module that modifies this arm.
As a bonus action, this arm splits into any two different modes from among those the arm can use. This lasts for 1 minute, after which the arm reforms into the mech’s choice of the two modes it was using. The mech can still use a bonus action to swap out modes with this arm, choosing one or both to change.
- Pressure Overload
The mech’s legs are specially designed to build up massive amounts of pressure, increasing its mobility. The mech’s speed increases by 10 feet, and any effect that would reduce the mech’s speed has the speed reduction reduced by 10 feet, to a minimum of 0. For example, the spell ray of frost would not not reduce the mech’s speed, but effects that don’t specify a specific amount of reduction (such as being grappled) are unaffected.
As a bonus action, the mech can release all the stored pressure in its legs to take the Dash action (no action required) and gain a high jump distance and a long jump distance equal to half its movement speed until the end of the turn, with or without a running start. If the mech were to fall during this turn, it increases the distance it can fall before calculating the distance it fell by a number of feet equal to 10 x the mech’s combined Strength and Constitution modifiers (minimum of 20 feet). The mech then does not benefit from the passive speed benefits of this feature until it regains use of this feature. For example, a mech with a Strength and Constitution of 16 each could fall 80 feet, but only take fall damage for 20 of those feet.
Mechanical Expertise
Starting at 15th level, your knowledge of the inner workings of machines and other constructs makes you a master at identifying them and how they work. If you spend at least 1 minute with a construct or mechanical device outside of combat, you can learn some of its characteristics. If it’s a creature, the DM will state true or false for if the construct has up to ten of the stats in the following list. You can pick the same option twice. If it’s an object, this feature has the same effects as the spell identify.
- Choose one ability score, then choose above 20 or below 16.
- Choose AC 20 or higher, or AC 19 or lower.
- Choose speed 40 or higher, or speed 35 or lower.
- Choose one condition immunity.
- Choose one saving throw proficiency.
- Choose one damage type, then choose immunity or resistance or vulnerability
Mech Specializations
Each pilot designs their mech to their own specifications. Some prefer to build massive, hulking monstrosities of metal while others rely on magical enhancements to improve their builds. Some try to make their mechs as small as possible, fitting them to their body like a suit of armor. How you build your mech defines what it can do.
Body Mech
- Mech Suit
When you choose this personalization at 1st level, your mech is designed more like a suit of armor than a vehicle. Rather than build a massive machine that you sit inside, you instead build a mechanized suit of armor that you can wear. This mech suit functions with the following modifications:
Size. The mech is the same size as you are, at only 1/10 your height taller and 1/10 your width and thickness wider and thicker than you. It also only weighs twice as much as you do, and when not being worn fits inside of a backpack, filling it completely.
Speed. The mech’s speed is no longer based on size. Instead, the mech’s base speed is half your speed plus 5 x the mech’s Dexterity modifier.
Ability Scores. You can use your Strength, Dexterity, and Constitution modifiers in place of the mech’s when making ability checks, attack rolls, or saving throws if your scores are higher.
Actions. The mech gets either the integrated weapon or the arm cannon for each arm, not both. A creature’s hands fit into the mech’s arms, which then pull on strings or push buttons to use the weapons and modules equipped to the extra length of the mech’s arms.
Features and Traits. The mech is considered heavy armor for the purposes of taking a long rest and for donning and doffing it, instead of requiring a creature’s movement and action to enter and activate it. In addition, only you or creatures of similar shape, size and physique may use the mech. The mech activates as soon as it is fully equipped, and must be deactivated before you can start doffing it. The mech also has only 1 of each slot type except for Pilot slots, of which it has 0 slots.
- Improved Mechanics
Starting at 6th level, the mech can stand up from prone by spending the normal amount of movement, instead of all its movement. In addition, the mech may anchor itself by spending only half its movement, and while anchored it only has disadvantage on Dexterity saving throws as described in the stat block at the end of the class description, and its speed is only reduced by half when anchored, not to 0.
The mech also gains 1 Right Arm slot and 1 Left Arm slot (2 total for each).
- Power Core
At 14th level, you have developed a special magical energy source for your mech suit, which fits into the chestplate for the mech. This helps fuel each of your mech’s modules, increasing the number of times they can be used. The power core has a number of charges equal to half your mech pilot level (rounded down), which can be expended whenever the mech uses one of its modules in place of one of the module’s uses. If the module regains expended uses when the mech finishes a short or long rest, it costs 1 charge. If the feature regains expended uses when the mech finishes a long rest, it costs 2 charges. The core regains 1d4 charges when the mech finishes a short rest, and all expended charges when it finishes a long rest.
The mech also gains 1 Legs slot (2 total).
- Biomechanical Fusion
By 20th level, you have learned how to combine your mech with the flesh of your body. Anytime after gaining this feature, you may spend three consecutive days fusing the pieces of your mech into your body. At the end of the three days, you and the mech are one, and gain the following benefits:
- You and the mech share the same pool of hit points, the mech cannot be doffed until you die, and the mech cannot be deactivated until you fall unconscious. You and the mech are now considered to be the same creature, but you are still considered to be inside of it.
- The mech does not impede your ability to take long rests and instead allows you to finish a long rest in half the time it would normally take you, nor does it impede any of your abilities to move or jump. For example, if you can crawl or swim faster than it can, then you use that speed instead.
- The mech’s Strength, Dexterity, and Constitution scores each increase by 4, to a maximum of 16, or if the scores were already 15 or higher, they instead increase by 3, to a maximum of 20, or if the scores were already 20 or higher, they instead increase by 2, to a maximum of 24. You may then use those scores in place of your own if they are higher than yours.
- Once during each of your turns, you can spend 10 of your hit points to give your Power Core feature one charge.
- Your creature subtype (i.e. elf, human, gnome, demon, etc) becomes "mech". You are still a humanoid, and you keep your racial features.
In addition, whether or not you fuse yourself with your mech, your power core is permanently fused with one of your mech’s modules. Choose one of your mech’s modules. The power core has an additional 4 charges, which can only be used for that module.
The mech also gains 1 Pilot slot and 1 Body slot, and an extra module (as described under Universal Module) that requires 1 Pilot slot.
Enchanted Mech
- Magical Mechanics
When you choose this personalization at 1st level, your mech functions primarily on magic effects that you infuse the mech with. The enchantments that allow it to function cause its weapon attacks to be magical. In addition, if subjected to a spell or effect that negates magic, the mech is considered a magic artifact for the purpose of resisting that effect, and merely deactivates for no longer than 24 hours if a spell or effect would remove its enchantments.
- Integrated Magic Items
At 6th level, you have learned how to combine your mech with other magical items. Whenever you attune to a magical item, you may incorporate it into the mech. Magic weapons can replace integrated weapons, magic armor properties are applied to the mech (but not the armor’s AC), and the mech can use all of any magic item’s properties as though it were attuned to the item instead of you. Magic items incorporated into the mech have no effect while the mech is deactivated.
The mech can only have one magic item incorporated into it, and the item can be no rarer than uncommon. This number and rarity increases to two and rare at 14th level and to three and very rare at 20th level.
- Elemental Enhancement
Beginning at 14th level, the enchantments that allow your mech to function combine with certain modules in your mech and some of magical effects that your mech may be able to create through the use of any incorporated magic items. Any time the mech rolls damage for a module, spell, or effect that deals acid, cold, fire, lightning, poison, or thunder damage, it can reroll any 1s or 2s that are rolled and must use the new rolls, even if it’s another 1 or 2.
In addition, if the mech has resistance to cold, fire, or lightning damage, any creature inside the mech while it is activated is immune to that damage type.
- Antimagic Systems
At 20th level, the mech runs on such powerful enchantments that other magical effects have extreme trouble affecting it. The mech and all creatures inside of it can’t be affected or detected by spells of 4th level or lower unless they want to be. They have advantage on saving throws against all other spells and magical effects.
Machine Mech
- High-Tech Systems
When you choose this personalization at 1st level, you build your mechs with incredible precision, using techniques for technologies far more advanced than anyone would have thought possible. When determining all of your mech’s statistics, each of your ability scores are considered to be 1 point higher than they normally would. For example, if you have a Charisma of 17, the mech treats that score as an 18 when determining its Constitution, hit points, etc. If you have a Dexterity of 11, the mech treats that as a 12 when determining its speed.
- Enhanced Weaponry
At 6th level, the innate weapons in the mech are upgraded to hit devastating force. Both the integrated weapons and the Arm Cannons deal an additional die of damage, and critical hits with them also deal an additional die of damage.
- Massive Machine
By 14th level, your constant improvements to your mech have allowed you to increase its size to massive proportions. When you gain this feature, and each time you rebuild your mech, you may choose to build it two sizes larger than your normal size instead of one. If you do, you double its height, width, and thickness, and multiply its weight by 8. Other mech stats that are based on size also change as well. In addition, the mech gains one additional Right Arm, Left Arm, Legs, and Body slot. However, the mech’s Dexterity score decreases by 2, to a minimum of 6. The mech can now only have creatures two or more sizes smaller than it enter it, instead of one. A creature must be three or less sizes smaller than the mech to activate it from inside the inside. When rebuilding your mech or building additional copies, building it at an increased size doubles the amount of time it takes to do so, and it costs 10 times as many gold pieces.
- Remote Control
At 20th level, you create a hand-held mechanical device infused with enough magic to allow it to control your mech from the outside. A creature no longer needs to enter the mech to activate it: instead, a creature within 300 feet of the mech and holding the remote may use an action to activate the mech. The remote has enough controls to use all of the mech’s modules and features, but requires the creature’s action each turn to continue moving and taking actions and bonus actions. The mech takes its own actions, bonus actions, and can move by itself so long as the creature with the remote is using its action each turn to tell the mech to do each of those things. The creature with the remote can still take its own bonus actions, reactions, and can move. The creature with the remote must be able to see the mech to be able to pilot it with the remote, and the creature must also be able to see any target or point for the mech to be able to choose that target or point for each of its attacks and features.
If a creature was piloting the mech from the inside when another creature begins piloting the mech with the remote, the creature inside the mech loses complete control of the mech and cannot deactivate it until the end of its next turn. The creature regains control of the mech if the creature with the remote stops piloting the mech.
If you have multiple mechs, you may only pilot one mech at a time, and each mech requires its own remote. Each additional remote requires 2 hours of time and 500gp to create. Each mech can have multiple remotes that it can be piloted with, but the mech still has the usual penalties for being piloted by creatures other than you even if the other creatures use the remote.
Module Lists
Combat Modules
These modules enhance your mech’s incredible combat capabilities.
- Additional Plating
The mech’s maximum hit points increase by 2 for each level you have in this class.
This module can be chosen multiple times, with additional copies not requiring additional Body slots.
Slots Required: 1 Body
- Flexible Joints
The mech is capable of performing much more agile motions. Its Strength and Dexterity scores are switched, and it may use Dexterity in place of Strength when making attack rolls with its weapons and modules, when determining the saving throw DCs of its modules, and when determining how many times its modules may be used. It may also determine its AC as 12 + its Dexterity modifier instead.
- Impact Distribution
The mech’s plating and frame distributes impacts more evenly at the cost of the inhabitants inside. The mech treats all bludgeoning, force, piercing, and slashing damage as Buffered Damage, as described in the The Mech feature, under Hit Points. However, all Buffered Damage is instead dealt only to the creature piloting the mech, not every creature inside the mech.
Slots Required: 1 Body
- Poison Gas
The mech is capable of creating clouds of noxious gas. As an action, the mech expels a cloud of noxious gas, which fills a 20-foot sphere in front of it. Each creature that starts its turn in the cloud or enters the cloud for the first time during a turn must make a Constitution saving throw, taking 2d10 poison damage and becoming poisoned for one minute on a failed saving throw, or half as much damage on a successful one. A creature poisoned in this way can remake the save at the end of each of its turns, ending the effect on itself on a success. The cloud heavily obscures the area, and can be dispersed by a strong breeze. It otherwise lasts for 10 minutes.
The damage of this module increases by 1d10 at 9th level (3d10) and again at 17th level (4d10).
Once the mech uses this module, it can’t do so again until it finishes a short or long rest.
Slots Required: 1 Body
- Tempered Plating
Your mech gains a +1 bonus to AC.
For every two copies of this module the mech has, it gains another +1 bonus to AC.
This module can be chosen multiple times.
- Toxic Weapons
The mech produces a toxic substance which is stored in a small chamber in one of its arms. As a bonus action during its turn, the mech can release this chemical onto its equipped weapon on that arm. The next time that weapon hits, the target must succeed on a Constitution saving throw or take 2d6 poison damage, or half as much on a successful save.
This module can be used a number of times equal to your proficiency bonus, and it regains all expended uses when the mech finishes a long rest.
The damage of this module increases by 2d6 at 9th level (4d6) and again at 17th level (6d6).
This module can be chosen twice, choosing the other arm the second time. The mech can use both modules with the same bonus action.
Slots Required: 1 Right Arm OR 1 Left Arm
- Protective Plating
Your mech has additional plating on its exterior that protects it from certain types of damage. Choose one of the following damage types: cold, fire, lightning, necrotic, or radiant. The mech has resistance to that damage type, and treats it as impact damage instead of buffered damage.
This module can be chosen multiple times, choosing a different damage type each time.
- Innate Shielding
Choose one of the mech’s arms. That arm can turn into a shield, which confers the standard +2 bonus to AC while equipped.
This module can be chosen twice, incorporating the shield into the other arm the second time. If both shields are equipped, the mech has half cover from all attacks and effects.
Slots Required: 1 Right Arm OR 1 Left Arm
- Protective Shielding (Prerequisite: Protective Plating and Innate Shielding modules)
Choose one of the mech’s Innate Shielding modules. All of the mech's Protective Plating modules are integrated with that Innate Shielding module, providing vastly enhanced effects. As a reaction to the mech being subjected to an attack or effect that deals damage of one of the mech's Protective Plating damage types, the mech can raise the shield to block the effect, preventing all damage from the attack against itself and any creature inside. The mech also acts as full cover against the effect for any creatures in a line behind the mech.
The mech can use this module a number of times equal to its Strength modifier, and regains all expended uses when it finishes a short or long rest.
- Fire Cone
The mech is capable of spraying deadly flame, coating the area in front of it. As an action while piloting the mech, you can cause it to create a 15-foot cone of fire originating from it. Each creature in the area must succeed on a Dexterity saving throw or take 3d6 fire damage, or half as much on a successful save. The mech must have the arm’s Arm Cannon equipped.
The damage of this module increases by 1d6 at 9th level (4d6) and again at 17th level (5d6).
This module can be used a number of times equal to your proficiency bonus, and it regains all expended uses when the mech finishes a short or long rest.
Slots Required: 1 Right Arm OR 1 Left Arm
- Incineration (Prerequisite: Fire Cone module)
The flames produced by your mech increase in intensity, allowing them to travel further and burn more vigorously. The Fire Cone module produces a cone that extends 15 feet further and deals an additional 2d6 damage.
The increase to damage becomes 3d6 at 13th level.
This module may be chosen multiple times.
- Efficient Fuel (Prerequisite: Fire Cone module)
Choose one of the mech's Fire Cone modules. The mech more efficiently produces streams of deadly flames from that arm and can use that Fire Cone module an additional three times between rests.
Slots Required: The same type of slot that the prerequisite module uses.
- Fire Blasts
Your mech can produce explosive bursts of fire that detonate with small explosions. As an action while piloting your mech, you can point one of your mech’s arms to a point within 120 feet of the mech and release a tiny orange bead, which blossoms with a loud pop into a 10-foot radius sphere of fire. Each creature in the area must succeed on a Dexterity saving throw or take 2d6 fire damage, or half as much damage on a successful save. The fire spreads around corners. The mech must have the arm’s Arm Cannon equipped.
The damage of this module increases by 2d6 at 9th level (4d6) and again at 17th level (6d6).
This module can be used a number of times equal to your proficiency bonus, and regains all expended uses when the mech finishes a short or long rest.
Slots Required: 1 Right Arm OR 1 Left Arm
- Homing Blasts (Prerequisite: Fire Blasts module)
The explosive blasts or fire produced by your mech are infused with a bit of magic, allowing them to accurately target creatures. The Fire Blast module’s range increases by 30 feet, and the mech may instead make a ranged spell attack against a creature within range when it uses the module, dealing 1d10 fire damage on a hit and the creature automatically fails its save. On a miss, the creature makes the saving throw as normal. Hit or miss, other creatures in the area of effect make their saving throw as normal. If moved to the Body slot, the mech no longer needs to have the arm’s Arm Cannon equipped.
The attack instead deals 2d10 damage at 13th level.
This module may be chosen multiple times, further increasing the range and giving the mech a +1 bonus to the attack roll for each additional time the module is chosen.
Slots Required: The prerequisite module may use 1 Body slot instead of the arm slot.
- Increased Fire Blast Capacity (Prerequisite: Fire Blasts module)
You mech is capable of producing more explosive blasts of fire than normal. The Fire Blasts module can be used an additional three times between rests.
Slots Required: The same type of slot that the prerequisite module uses.
- Stronger Blasts (Prerequisite: Fire Blasts module)
The explosive blasts of fire created by your mech increase in intensity. The radius of the Fire Blasts module’s spheres increases by 10 feet, and the damage increases by 2d6.
This module may be chosen multiple times.
- Blast Barrage (Prerequisite: Fire Blasts module)
The mech can more rapidly release its explosive blasts of fire. Each time it uses the Fire Blasts module, it may expend an additional use of the module to release an additional blast of fire to a different point in range, then roll a d6. On a 4, 5 or 6, it regains one use of the Fire Blasts module. If a target would be in the radius of more than one sphere of fire, it only makes the saving throw once and does not take any extra damage.
This module may be chosen multiple times, allowing the mech to release even more blasts of fire simultaneously.
- Shock Bolt
The mech can produce a sudden burst of lightning to shock other creatures. The mech may, as an action while the arm's Arm Cannon is equipped, aim one of its arms at a creature within 150 feet of it and release a bolt of electrical energy at that creature. The mech makes a ranged spell attack. On a hit, the creature takes 2d12 lightning damage and it can’t take reactions until the start of the mech’s next turn.
The damage of this module increases by 1d12 at 9th level (3d12) and again at 17th level (4d12).
This module can be used a number of times equal to your proficiency bonus, and it regains all expended uses when the mech finishes a short or long rest.
Slots Required: 1 Right Arm OR 1 Left Arm
- Beam Weaponry (Prerequisite: Shock Bolt module)
The mech’s electrical releases jump from one place to another, not stopping until they run out of energy. The Shock Bolt module is now a 2.5 ft by 150 ft line, and it deals an additional 1d12 damage. Creatures in the area make a Dexterity saving throw instead of the mech making an attack roll, and take half as much on a successful save.
The increase to damage increases to 2d12 at 13th level.
- Static Discharge (Prerequisite: Shock Bolt module)
The mech can electrocute enemies within close proximity of itself. As an action, it can expend one use of its Shock Bolt module to make a melee spell attack against a creature within 5 feet of it. On a hit, the creature takes an additional 2d12 lightning damage and is stunned until the start of its next turn. If a creature outside the mech is touching it when it uses this module, the creature must succeed on a Dexterity saving throw or suffer the same effects, taking half as much damage and not getting stunned on a successful save. The mech must have the arm’s hand equipped. If moved to the Body slot, the mech can use either arm’s Arm Cannon instead for the ranged version, or either arm’s hand for the melee attack. The mech can also choose forgo making the melee attack if the module was moved to the Body slot, which gives the creatures disadvantage on their save.
The increase to damage increases to 3d12 at 13th level.
Slots Required: The prerequisite module may use 1 Body slot instead of the arm slot.
- Electric Capacitors (Prerequisite: Shock Bolt module)
The mech is equipped with devices that store some of its excess energy. The mech can use its Shock Bolt module an additional three times.
Slots Required: The same type of slot that the prerequisite module uses.
- Bladed Armor (Prerequisite: 5th level)
The mech is covered in sharp blades. Any creature that touches the mech or hits it with a melee attack from within 5 feet takes an additional 1d6 slashing damage, and the mech’s unarmed strikes also deal this damage. The mech can choose if the spikes will harm a creature that touches it.
This module can be chosen multiple times, and does not consume additional Body slots when chosen multiple times.
Slots Required: 1 Body
- Disengage Safety (Prerequisite: 8th level)
The mech can be piloted with disregard to the safety of itself and its occupants. At the start of each of its turns, the mech can choose to begin acting violently. The mech can take an additional action during its turn and has advantage on all attack rolls while acting violently. However, each other creature has advantage on attack rolls against it and it is vulnerable to all damage while acting violently. The effect ends at the start of the mech’s next turn.
- Percussive Wave (Prerequisite: 8th level)
The mech is capable of emitting a deafening shockwave of sound, damaging and inhibiting creatures around it. The mech can, as an action, force each creature outside of it and within 20 feet of it to make a Constitution saving throw. A creature takes 3d8 thunder damage and is deafened for 1 minute on a failed saving throw, or half as much damage on a successful save.
The damage of this module increases by 2d8 at 15th level (5d8).
This module can be used a number of times equal to the mech’s Strength modifier, and it regains all expended uses when the mech finishes a long rest.
- Extra Attack (Prerequisite: 5th level)
The mech can attack twice, instead of once, whenever it takes the Attack action on its turn.
Slots Required: 1 Right Arm OR 1 Left Arm
- Second Extra Attack (Prerequisites: 11th level, First Extra Attack module)
The mech can attack three times, instead of two, whenever it takes the Attack action on its turn.
Slots Required: 1 Right Arm OR 1 Left Arm
- Third Extra Attack (Prerequisites: 20th level, Second Extra Attack module)
The mech can attack four times, instead of three, whenever it takes the Attack action on its turn.
Slots Required: 1 Right Arm AND 1 Left Arm
Utility Modules
These modules are not necessarily combat-related but will still improve your mech's performance significantly.
- Grappling Hook
Choose one of your mech’s arms. That arm can turn into a grappling hook attached to a metal chain, with a winch inside the arm. The hook can be launched up to 60 feet away from the mech, allowing it to climb up steep slopes and even vertical ascents. The mech’s climbing speed for a vertical ascent is 5 feet, or twice that for a steep slope. These speeds cannot be increased by other features. The mech does not need to be against a solid surface to pull itself up vertically. The hook must have something for it to catch on to be used to climb, as normal.
This module can be chosen twice, choosing the other arm the second time. If both hooks are being used, the climbing speeds are doubled.
Slots Required: 1 Right Arm OR 1 Left Arm
- Headlights
The mech has two bullseye lanterns mounted to the front of it. They do not require fuel to function. They can be lit or snuffed as a bonus action while the mech is activated, and they last for one hour each. They regain all expended time when the mech finishes a short or long rest.
The maximum duration of the lanterns increases to 2 hours at 9th level and to 3 hours at 17th level.
Slots Required: 1 Pilot
- Mining Drill
Choose one of your mech’s arms. That arm can turn into a drill, allowing the mech to burrow through the ground. The mech has a burrow speed of 10 feet while it has a drill equipped. It can tunnel through solid rock at half its burrow speed, leaving a hole 1 foot taller than it is and 1 foot wider than it is in its wake. This speed only gains half the speed benefit of features and effects that increase the mech’s speed.
The burrow speed increases to 15 feet at 11th level.
This module can be selected twice, choosing the other arm the second time. If both drills are being used, the burrow speed is doubled.
Slots Required: 1 Right Arm OR 1 Left Arm
- PA System
The mech is equipped with sound-amplifying components. When a creature speaks while in the mech, it may choose to make its voice be able to be heard clearly from up to 300 feet away from the mech.
- Reinforced Frame
The motion systems in the mech use an advanced hydraulic pressure system to increase the weight it can bear. The mech’s carrying capacity (including maximum load and maximum lift) is doubled.
The multiplier is increased to triple, instead of double, at 11th level.
- Spring-Loaded Knees
The mech has powerful springs in its legs, allowing it a greater range of motion. The mech can crawl at the appropriate speed, and it can jump half the distance that another creature with the same Strength score could.
The mech can jump normal distances using this module at 11th level.
Slots Required: 1 Legs
- Improved Pistons
Both of the mech’s legs have larger, stronger parts to help it move faster. Your mech’s speed increases by 5 feet. This speed bonus is applied after determining if the mech is anchored.
The increase to speed becomes 10 feet at 11th level and to 15 feet at 18th level.
- Self-Lubricating Pylons (Prerequisite: Improved Pistons module)
The mech’s speed increases by another 10 feet, as with the Improved Pistons module.
This module can be chosen multiple times.
- Observation (Prerequisite: 6th level)
The mech has a specialized system of spy glasses and mirrors that reflect the images of its surroundings into just a few, easy-to-see locations inside of it. While in the mech, a creature is considered proficient with Perception checks, and it doubles its proficiency bonus for Perception checks that rely on sight if it was already proficient.
Slots Required: 1 Pilot
- Heartbeat Monitor (Prerequisite: 6th level)
The mech has hyper-sensitive sensor plating that can sense even the slightest vibrations in extremely close proximity to the mech. While piloting the mech, a creature is considered proficient in Wisdom (Insight) checks to determine if a creature within 5 feet of the mech is lying and in Wisdom (Medicine) checks to determine if a creature within 5 feet of the mech is dead or dying. The mech also has blindsight and tremorsense out to a range of 5 feet, information which it conveys to any creature inside it through a series of drums.
Slots Required: 1 Pilot
- Ejection Seat (Prerequisite: 6th level)
The mech is equipped with a spring-loaded seat that can throw you out of harm’s way at the pull of a lever. A creature in the mech may, as a reaction to the mech being targeted by an attack or spell or being included in the area of a spell or effect, launch the seat and any creatures sitting in the seat 40 feet away from the mech in any direction. This movement does not provoke opportunity attacks. For the first 20 feet the seat moves horizontally, it moves that distance vertically upwards as well. If the seat continues moving beyond 20 feet and there is nothing to hold it aloft, it begins falling at a rate of 5 feet for every 5 feet it moves horizontally, up to the remaining 20 feet. If still nothing holds the seat aloft once this distance has been reached, it plummets straight down, and any creature in the seat calculates the distance fallen from this point. The mech immediately deactivates and is treated as though it wasn’t being piloted for the purpose of damage. Until the end of the current turn, any attacks against the mech automatically hit, and the mech fails all saving throws against spells and effects. Any creature that pilots the mech once this module has been used doesn’t benefit from the mech’s Cockpit feature until the mech finishes a short or long rest. Once used, this module can’t be used again until the mech finishes a short or long rest.
Slots Required: 1 Pilot
- Detachable Parts (Prerequisite: 6th level)
Parts of the mech have joints that allow them to be detached and reattached. A creature can use its action while the mech is deactivated to remove one of the mech’s arms or legs and carry it, provided the creature is strong enough to lift the mech part. If held, the mech part can be used by the creature holding it as if the mech were activated. The mech can be activated while it is missing parts, but cannot use the removed parts. For a part to be reattached to the mech, the mech must be deactivated.
Slots Required: 1 Body
- Active Camouflage (Prerequisite: 9th level)
The mech has intuitive color-changing plating that camouflages the mech to its surroundings. The mech has a +3 bonus to Dexterity (Stealth) checks.
The bonus of this module increases to +5 at 17th level.
This module can be chosen multiple times.
Slots Required: 1 Body
- Lead Shielding (Prerequisite: 9th level)
The mech's cockpit is protected by a thin sheet of lead. While in the mech, creatures and objects cannot be targeted by divination spells, and the thoughts of creatures inside the mech cannot be read creatures outside the mech.
- Atmospheric Isolation (Prerequisite: 9th level)
The mech has airtight and watertight plating, and has two air tanks attached to its sides. Each tank, when full of clean air, provides an hour of breathable air. The mech can activate or deactivate this plating and the air tanks as a bonus action. While the plating is activated, all creatures inside the mech have complete immunity to spells and effects that create toxic gasses or noxious fumes, and neither air nor water cannot enter or exit the mech.
Slots Required: 1 Body
- Aquatic Propulsion (Prerequisite: Atmospheric Isolation module)
The mech has a mechanical system that helps it move underwater. The mech gains a swim speed of 15 feet, or its swim speed increases by 15 feet if it already had a swim speed.
The swim speed or increase to swim speed becomes 20 feet at 18th level.
This module can be chosen multiple times, increasing its swim speed each time.
Slots required: 1 Body OR 1 Legs
- Thrusters (Prerequisite: 9th level)
Your mech is equipped with a special device in each of its hands. While both arms have the hands equipped, the mech can discharge both devices to take the Dash action (no action required) during its turn. While the mech has at least one hand equipped, if it takes the Attack action during its turn, it can replace one of the attacks it makes with a melee spell attack by discharging the device on that arm. The mech makes a melee spell attack against a target within 10 feet of it, dealing 4d6 fire damage if the attack hits. Each device can be discharged three times, regaining all uses when the mech finishes a short or long rest.
The optional damaging feature of this module increases by 2d6 at 17th level (6d6).
Slots Required: 1 Right Arm AND 1 Left Arm
- Enhanced Thruster Efficiency (Prerequisite: Thrusters module)
The thrusters in your mech consume their power source more efficiently, allowing them to be used more often. Each thruster can be used two additional times.
- Flight (Prerequisites: 15th level, Thrusters module)
Your mech is equipped with two more copies of the same special device implanted in its hands, now in the soles of the mech’s feet as well. The additions of these extra thrusters allow the mech to fly. The mech may, as an action during its turn, discharge any two of its thrusters to activate all four thrusters and gain a fly speed equal to half its walking speed. The mech must continue using its action and discharging one of its thrusters each turn to keep all four thrusters activated. A thruster does not deactivate until either the mech stops using its action to keep it activated or until all four thrusters have been completely discharged. All four thrusters must have at least one use left for the mech to begin using this module. Additionally, the optional damaging feature of the thrusters deals an additional 1d6 damage, and the mech can use any two of its thrusters to Dash instead of just its hands, as with the Thrusters module.
Slots Required: 1 Legs
- Sentry Mode (Prerequisite: 12th level)
While the mech is deactivated and is capable of being activated, it enters sentry mode. While in sentry mode, it has darkvision out to a range of 15 feet and a passive Perception of 10 + your Intelligence modifier. If it senses a creature that you did not designate as a friendly creature moving within its vision range, it creates a loud ringing noise audible from 900 feet away. Creatures that start their turn, end their turn, or come within 15 feet of the mech for the first time during their turn while the mech is making this ringing noise must succeed on a Constitution saving throw or be deafened for one minute. If the mech takes damage while creating the ringing noise, it can use its reaction to use any one of the its modules at random, targeting a random creature or centering the effect on a random creature within the mech’s vision. The mech does not need to be activated or piloted to use this reaction. The mech stops making the ringing noise if you or a designated creature comes within 15 feet of it or shouts at it to stop making the noise while within 45 feet of it.
- Auto-Pilot (Prerequisites: 18th level and the Sentry Mode module)
The mech is capable of moving on its own without being controlled. While in sentry mode, it follows you at a distance of between 10 and 30 feet (you choose each time it enters sentry mode) and at a speed of 30 feet per turn. Its darkvision range increases to 30 feet. In addition, you can designate type of creatures (i.e. deer, commoners, trolls, etc.) that it either won't start its alarm for or that it will start its alarm for, instead of choosing specific creatures for the mech to ignore. Finally, when the mech uses its reaction to use a random module against a potential hostile, the mech instead chooses both the module and the creature it wants to target, or the point where the module's effect is centered. If the mech has the Automated Protection Mech Fighting Style, it no longer needs to be piloted to make use of the feature.
Slots Required: 1 Pilot
Sample Mech Stat Block
This is a sample stat block for a 5th level human mech pilot’s mech with no modules or other features. The mech has clubs as its integrated weapons. The mech pilot’s stats for this sample stat block are as follows: Strength 12 (+1), Dexterity 16 (+3), Constitution 8 (-1), Intelligence 18 (+4), Wisdom 14 (+2), Charisma 12 (+1) Regardless of your features, your mech will always have the Anchoring, Automaton, Cockpit, and Piloted special traits. Some of these traits can be modified by the various Module Lists a mech pilot can choose when gaining levels in this class.

Large construct, unaligned Armor Class 16 (natural armor)
Damage Immunities poison, psychic Anchoring. The mech can use all of its movement during its turn to become anchored. While anchored, its base speed becomes 0 but it can still benefit from effects that increase speed. While anchored, the mech automatically fails Dexterity saving throws but has advantage on Strength saving throws. The mech is also immune to the prone condition while anchored. During its turn on subsequent turns, the mech can stop being anchored at any time, but it cannot move until the start of its next turn. Automaton. The mech doesn’t need to eat, drink, sleep, or breath, but it also cannot regain hit points by resting. The mech is also immune to any effect that would reduce its hit point maximum. The mech may, as a reaction to having the spell mending or similar magic cast upon it, regain 1d6 hit points plus another 1d6 for each level the spell was cast at. The mech cannot use this feature again until it finishes a long rest. Cockpit. A creature that is one or more sizes smaller than the mech can fit inside the mech. A creature inside the mech while the mech is activated has full cover from attacks and effects from outside the mech. Air, water, and gasses can still seep into the mech, though. Before applying weaknesses/resistances/immunities, if there is at least one creature inside the mech, the mech takes half damage from cold, fire, lightning, necrotic, radiant, and thunder damage and each creature inside the mech takes the same amount of damage. If an attack that deals poison or psychic damage hits the mech, each creature inside takes the damage instead. A spell or effect that requires the mech to make an Intelligence, Wisdom, or Charisma saving throw has a random creature inside the mech make the save against the effect instead, with the creature making the save being subjected to the spell or effect instead. Piloted. The mech is an inanimate object and must be activated by another creature to move or take actions, bonus actions, or reactions. The mech can only be activated by a creature that is two or less sizes smaller than it. That creature must use 15 feet of movement to enter the mech, after which the creature and the mech share the same space. The creature can then use its action to activate the mech. Once the mech is activated, the creature can use its action, bonus action, and/or reaction each turn to pilot the mech and have it perform any of the actions, bonus actions, and/or reactions it has available, as well as to have it move. The creature can also use its action to deactivate the mech. Once deactivated, the creature can leave the mech’s space by moving normally. If the mech used any of its movement during a turn, the creature piloting the mech cannot use any of its own movement during the same turn. If the mech is reduced to 0 hit points, the mech falls prone and deactivates, and excess damage is dealt to the creature piloting it. The mech cannot be reactivated until it regains at least half of its hit points, and the creature piloting it is prone until it leaves the mech. Anytime the mech must make a choice while activated, the creature piloting the mech makes the choice instead. The mech uses the same senses as the creature piloting it when determining what it can see. ACTIONSClub. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 1d4 + 4 bludgeoning damage. Arm Cannon. Ranged Weapon Attack: +6 to hit, range 60/180 ft., one target. Hit: 1d8 + 4 piercing damage. Hit or miss, if the mech isn't anchored, it must succeed on a DC 15 Dexterity saving throw or fall prone.
