Mechromancer

Mechromancers are martially skilled artisans, doctors and inventors who collect and scavenge warforged body parts from warforged corpses that dot ancient battlefields and ruins, grafting them onto their own to enhance their combat and utilitarian abilities.

Note: Every time a feature states that you need to use warforged parts, you must expend a use of warforged parts from the box of warforged parts or another source. When you run out of warforged parts (which you will by 9th level), you will want to restock or you can't craft more grafts, etc. You can acquire more by buying, finding, scavenging or crafting them (at DM's discretion), but they are costly and difficult to come by. If you try to sell your warforged parts, you should find that it is rarer to find someone wanting to buy them that someone wanting to sell them. Alternatively, you can work with the DM to reskin the mechanical body part replacement with something else (like biological mutation, some kind of corruption, etc), but you will need to figure out some other source for the materials for your grafts.

Graft

At 1st level you can learn two new grafts of your choice and have grafted the new warforged parts onto your body. You can spend a short rest using a Healer’s Kit, Tinker’s Tools and warforged parts to graft a graft that you know onto yourself. Additionally, you can spend a short rest using Tinker’s Tools to replace any number of existing grafts on yourself. Alternatively, you can spend a short rest using a Healer’s Kit, Tinker’s Tools and warforged parts to replace a missing body part of yours by grafting a prosthetic that functions like the missing body part onto yourself, without taking up the graft slot.

You learn additional grafts of your choice as you gain levels in this class according to the Number of Grafts Known column in the mechromancer table. The limit of grafts you can have at once are shown in the Number of Grafts column of the Mechromancer table. Whenever you gain a level in this class, you can forget a graft you know and learn a different graft instead. Grafts are detailed at the end of class description.

Unarmored Defense

Starting at 1st level, while not wearing armour your AC equals 10 + your Strength or Dexterity modifier + your Constitution modifier. Either Strength or Dexterity can be used for unarmoured defense, depending on which one has a higher value. You can use a shield and still gain this benefit.

Nano Regeneration

Starting at 2nd level you gain temporary hit points equal to your mechromancer level plus your Constitution modifier (minimum of 1) at the end of a short or long rest.

Fighting Style

At 3rd level and again at 7th, and 15th level you adopt a particular style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if you later get to choose again.

Archery
You gain a +2 bonus to attack rolls you make with ranged weapons.

Blind Fighting
You have blindsight with a range of 10 feet. Within that range, you can effectively see anything that isn't behind total cover, even if you're blinded or in darkness. Moreover, you can see an invisible creature within that range, unless the creature successfully hides from you.

Defense
While you are not wearing armor, you gain a +1 bonus to AC.

Dueling
When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

Great Weapon Fighting
When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Interception
When a creature you can see hits a target, other than you, within 5 feet of you with an attack, you can use your reaction to reduce the damage the target takes by 1d10 + your proficiency bonus (to a minimum of 0 damage). You must be wielding a shield or a simple or martial weapon to use this reaction.

Protection
When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.

Superior Technique
You learn one maneuver of your choice from among those available to the fighter Battle Master archetype. If a maneuver you use requires your target to make a saving throw to resist the maneuver's effects, the saving throw DC equals 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice). You gain one superiority die, which is a d6 (this die is added to any superiority dice you have from another source). This die is used to fuel your maneuvers. A superiority die is expended when you use it. You regain your expended superiority dice when you finish a short or long rest.

Two-Weapon Fighting
When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Close Quarters Shooter (UA)
When making a ranged attack while you are within 5 feet of a hostile creature, you do not have disadvantage on the attack roll. Your ranged attacks ignore half cover and three-quarters cover against targets within 30 feet of you. You have a +1 bonus to attack rolls on ranged attacks.

Thrown Weapon Fighting (UA)
You can draw a weapon that has the thrown property as part of the attack you make with the weapon. In addition, when you hit with a ranged attack using a thrown weapon, you gain a +2 bonus to the damage roll.

Tunnel Fighter (UA)
As a bonus action, you can enter a defensive stance that lasts until the start of your next turn. While in your defensive stance, you can make opportunity attacks without using your reaction, and you can use your reaction to make a melee attack against a creature that moves more than 5 feet while within your reach.

Unarmed Fighting (UA)
Your unarmed strikes can deal bludgeoning damage equal to 1d6 + your Strength modifier on a hit. If you aren't wielding any weapons or a shield when you make the attack roll, the d6 becomes a d8. At the start of each of your turns, you can deal 1d4 bludgeoning damage to one creature grappled by you.

Fencing
When you are wielding a melee weapon in one hand and holding nothing in the other, you gain a +2 bonus to attack rolls with that weapon.

Ability Score Increase

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.

Martial Versatility (Optional)

Whenever you reach a level in this class that grants the Ability Score Improvement feature, you can replace a fighting style you know with another fighting style available to mechromancers. This replacement represents a shift of focus in your martial practice.

Extra Attack

Starting at 5th level, a Mechromancer can attack twice, instead of once, whenever you take the attack action on your turn. The number of attacks increases to three when you reach 11th level.

Magical Grafts

Starting at 6th level, your attacks with weapons wielded by grafted body parts and attacks with graft weapons count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Graft Upgrade

At 9th level, you can upgrade a graft of your choice. Whenever you have that graft equipped, you gain access to its upgrade feature. If you have an upgraded graft equipped more than once at any time, only one of the grafts gain the benefits of the upgrade. Each time you gain a level in this class, you can change which graft you have upgraded. If a graft upgrade gives you options, you can also change which option you choose each time you gain a level in this class.

Ally Grafting

Starting at 10th level, you can spend a short rest using a Healer’s Kit, Tinker’s Tools and warforged parts to graft a graft that you know onto another creature within 5 feet for the duration of the short rest. Additionally, you can spend a short rest using Tinker’s Tools to replace any number of existing grafts on other creatures within 5 feet for the duration of the short rest. Alternatively, you can spend a short rest using a Healer’s Kit, Tinker’s Tools and warforged parts to replace a missing body part of a creature within 5 feet for the duration of the short rest, by grafting a prosthetic that functions like the missing body part onto the creature.

Once a graft has been grafted onto a creature, the creature can attune to the graft. If a creature isn’t attuned to a graft, it functions as the replaced body part would have (at DM’s discretion for grafts like Echo). Grafts cannot occupy the same body part slot. You are unable to graft a body part onto a creature that lacks the body part normally (For example: you are unable to graft an arm onto a giant snake). The limit of grafts you can have on other creatures are shown in the Number of Ally Grafts column of the Mechromancer table. Grafts are detailed at the end of class description. The number of slots a creature has for each body part is at DM's discretion.

When you die, the magic of your grafts on other creatures fade after a number of days equal to your Intelligence modifier (minimum of 1 day) and the grafts can only function as the replaced body parts would have (at DM’s discretion for grafts like Echo).

Blink Drive

Beginning at 18th level, you have a Blink Drive that has two charges. You can expend a charge to cast the blink spell without expending a spell slot. You regain all expended charges when you finish a short or long rest. Once per long rest, you can expend a charge to cast your choice of either the teleport spell or the plane shift spell without expending a spell slot.

Physical Amplifications

Starting at 20th level, you are now closer to machine than flesh, and can utilise your mechanical body to do extraordinary things. Your Unarmored Defence is now 12 + Strength or Dexterity modifier + Constitution modifier. In addition, your Strength and Dexterity scores increase by 2. Your maximum for both scores is also increased by 2. You also gain a +1 bonus to attack and damage rolls with graft weapons. You don’t need to eat or drink, and you are immune to disease. You don't need to sleep, and magic can't put you to sleep. Instead of sleeping, you must spend at least four hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn’t render you unconscious, and you can see and hear as normal. After resting in this way, you gain the same benefit a human would from 8 hours of sleep. Additionally, your jump distance, both vertical and horizontal, is doubled. You also count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

Grafts

Guidelines

You have 2 arm slots, 1 back slot, 1 chest slot, 2 hand slots, 1 head slot, and 2 leg slots (assuming you are humanoid). You can not return a body part slot to being organic without the regenerate spell or similar magic once it has been grafted, but you can use warforged parts to replace it with a prosthetic that functions like the organic body part, without taking up the graft slot. Grafts are categorised by slot then functionality. Base functionalities are Graft Casting, Enhancement, and Weapon. You are proficient with your graft weapons. A player can create custom grafts at DM's discretion. The custom graft must follow normal graft rules. It is also important to note that a custom graft shouldn't be able to do exactly what another graft does, but better. At DM's discretion, a player can also integrate a magic item into a graft (but must still maintain attunement with the magic item if it requires it).

Graft Casting

Some grafts allow you to cast spells. Intelligence is your spellcasting ability for your spells. You use your Intelligence whenever a spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for any spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

When you use your action on your turn to cast a "main hand" graft spell, you can make one light weapon attack (with either hand) as a bonus action.

Arms

Two arm grafts can be equipped, one to the "main arm" and one to the "off arm". Some Grafts have a prerequisite on needing a "main arm" or "off arm", if no prerequisite is named then the graft can be equipped to any arm you choose.

Adamantine Plate

+1 to AC and +1 to Constitution. Cannot increase an ability score above 20.

Upgrade: Additional +1 to AC. Any critical hit against you becomes a normal hit.

Bulk Arm

+1 to Strength or Dexterity. Can increase an ability score above 20 and your maximum for both scores is increased by 1. You gain a +1 bonus to ability checks made with the chosen ability score.

Upgrade: +1 to the ability score you didn't choose. You also gain a +1 bonus to ability checks made with that ability score. You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

Communication Recorders

Gain 9 Com Recorders that can be stored in the grafted arm and 1 Com Recorder built into the grafted arm. Com Recorders allow images and sound recordings to be sent to another Com Recorder and can be used by any creature with an Intelligence of 8 or higher. The interface on each Com Recorder requires a bonus action to use, and a Com Recorder requires 1 minute to fully delete or transmit a Record that can be up to 12 minutes long. The user of the Com Recorder may perform other actions while the deletion or transmission takes place, but must be within 60 feet of the Com Recorder while it's happening. The Com Recorders are Tiny objects that may be hung from a necklace, or worn in some other fashion. The Com Recorder data, called Record(s), may be projected from a Com Recorder onto any surface, much like a futuristic projector or monitor screen. Any images within line of sight and sounds audible within 30 feet of the Com Recorder may be recorded in a Record, with a maximum duration of 12 minutes per Record. This allows for 2 hours total of information to be recorded using every Com Recorder, enough for an interesting show at a tavern or theatre to be recorded in 10 segments. Additionally, each Record may be appended to, allowing for multiple recordings to be pieced together on each Com Recorder, much like a journal or personal voice log has multiple recordings. Multiple Records may be played simultaneously, offering multiple views, or creating a combined image, much like a hologram, of different viewpoints of the same recorded area.

Upgrade: Com Recorders gain one of the following effects of your choice of doubled audio range, triple the length of time for each Record, double the number of storable Com Recorders, or allowing multiple Records to be recorded on each Com Recorder that add up to a total of 12 minutes. Com Recorders also gain one of the following effects of your choice of truesight, motion sensing within 30 feet, transmitting and projecting a Record as it is being recorded, or another DM approved feature that may be useful.

Radar

Gain 6 Tracking Devices that can be stored in the grafted arm. Your grafted arm features a visible external radar that isn't active while you are unconscious or dead. The Tracking Devices appear on the radar and you know their exact positions as long as they are within 20 miles of you and on the same plane of existence. The Tracking Devices are Tiny objects that can be attached to any surface, or worn in some other fashion. They can be attached to a surface or creature within 30 feet as an action. To attach it in a way that it is concealed, the creature attaching it must make a Dexterity (Sleight of Hand) check. To attach it without another creature noticing, the check must be made against the creature's passive perception. If a creature attempts to look for a concealed Tracking Device, it must make an Intelligence (Investigation) check against the initial Dexterity (Sleight of Hand) check to find it.

Upgrade: You gain your choice of Tracking Devices gaining the ability to appear on the Radar regardless of how far away they are or if they are on a different plane of existence (you know exactly how far away they are or which plane of existence), Tracking Devices gaining the ability to become invisible after being placed until they are retrieved, or any creature within 60 feet appearing on the radar (you can distinguish between creatures and tracking devices), but you have no information about it other than it's exact location.

Secret Compartment

+1 to Strength, Dexterity or Constitution. Cannot increase an ability score above 20. Your arm has a secret compartment inside it that can hide up to two weapons that can be wielded with one hand or items that can fit in the palm of your hand. Stored objects can't be targeted by any divination magic or perceived through magical scrying sensors. Nonmagical objects stored for at least 1 hour count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage for up to 8 hours after they are removed. As a bonus action you can load or remove an item.

Upgrade: +1 to one of the two ability scores you didn't choose and your maximum for Strength, Dexterity and Constitution is also increased by 1. Additionally, the secret compartment in your arm transforms into an interior space considerably larger than its outside dimensions, and its opening can stretch open up to roughly 1 foot in diameter. It can store up to 500 pounds and any items inside weigh nothing for you, not exceeding a volume of 64 cubic feet. Retrieving an item requires a bonus action. Anything within this space can't be targeted by any divination magic or perceived through magical scrying sensors. If you unequip this graft or die, your secret compartment’s contents spill forth, unharmed. Breathing creatures inside can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate. Placing an extradimensional space created by a handy haversack, a bag of holding, a portable hole, or similar item inside your secret compartment instantly destroys the item and opens a gate to the Astral Plane. The gate originates in your space. You and any creature within 10 feet of you is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can’t be reopened.

Tool Kit

Allows you to hide any set of tools inside your arm. You can extend or retract any set of tools of your choice as a bonus action once per round. You also gain proficiency in a tool set of your choice (including game sets, instruments and vehicles), and if you requip this graft, you can change the chosen tool set proficiency.

Upgrade: +1 to Intelligence and your maximum for Intelligence is increased by 1. You also gain proficiency in all tool sets (including game sets, instruments and vehicles).

Arm Blade

Prerequisite: Main Arm

Allows you to hide a one handed retractable blade inside your arm. It has the finesse property and deals 1d8 + Strength or Dexterity modifier slashing damage modifier on a hit. You can extend or retract the weapon as a free action once per round.

Upgrade: Once per turn, the Arm Blade deals 2d6 additional damage of your choice of fire, lightning, or poison damage (which you choose when you upgrade it) on a hit. When you reach 15th level, you can change the damage type of the additional damage to force damage. Additionally, the Arm Blade gains a +1 bonus to hit and to damage rolls.

Arm Bow

Allows you to hide a retractable hand crossbow inside your arm. As a bonus action you can load or remove a clip of 8 bolts into the Arm Bow. You can extend or retract the weapon as a bonus action once per round.

Upgrade: Hand crossbow gains the Burst Fire and Versatile (2d6 with two hands) features, and it loses the Loading property. Additionally, as a free action you can load or remove a clip of 10 bolts into the Arm Bow. Additionally, the hand crossbow gains a +1 bonus to hit and to damage rolls.

Energy Whip

Allows you to hide an energy based whip inside your arm. You deal 1d4 + Dexterity modifier force damage with this weapon on a hit. You can extend or retract the weapon as a bonus action. This whip has similar statistics to a normal whip, concerning reach, and other properties. The Energy Whip is not a physical whip, but is visible as a weapon.

Upgrade: Your Energy Whip gains your choice of +20 feet reach, dealing 1d8 + Dexterity modifier force damage on a hit instead of 1d4 + Dexterity modifier force damage, being able to replace attacks with sweeping the Energy Whip in a 10-foot arc that forces each creature inside it to make a Dexterity saving throw (DC = 8 + to-hit modifier) or take the on-hit damage, or forcing any target to make a Strength saving throw against your mechromancer spell save DC on a hit or it is grappled by the Energy Whip. Creatures grappled by the Energy Whip in this way are restrained, but you are unable to target other creatures with attacks with the Energy Whip while a creature is grappled by the Energy Whip in this way. Additionally, the Energy Whip gains the light property and a +1 bonus to hit and damage rolls.

Grapple Gun

Allows you to hide a one handed retractable grappling hook inside your arm. This hook can attach to any surface or object, much like a regular hook could, and holds 60 feet of metallic cable, which is its range. When you take the attack action on your turn, you can replace one attack with firing the Grapple Gun. As a bonus action once per round you can reel the hook, pulling you in a straight line to any surface it is attached to. When you fire the Grapple Gun at a creature or an object instead of a surface, you must make a ranged weapon attack roll. On a hit, the target takes 1d4 + Dexterity modifier piercing damage and the hook is attached to it. If the hook attaches to a creature one size larger than you or smaller, it must make a Strength saving throw (DC = 8 + your Strength modifier + your proficiency bonus), or be grappled while the hook is attached to it. Any creature with the hook attached to it can attempt to detach it as an action by making the same Strength save, removing the hook on a success. When you reel the hook with a creature or an object attached, it gets pulled in a straight line to within 5 feet of you if it is the same size as you or smaller, and you get pulled in a straight line on top of it if it is one size larger than you or larger. After firing the Grapple Gun, you cannot fire it again until you reel the hook. Additionally, you cannot fire the Grapple Gun while the hook is attached to something. You can detach the hook as a free action on your turn. You can extend or retract the Grapple Gun as a bonus action once per round.

Upgrade: Your Grapple Gun gains your choice of a +2 bonus to hit and to damage rolls, forcing any target creature to make a Strength saving throw against being grappled when the hook attaches to it regardless of its size, or the cable's length increasing by half.

Net Launcher

Allows you to hide a retractable net launcher inside your arm. As an action you can load or remove a clip of 3 nets into the net launcher. The range of nets from the Net Launcher is quadrupled. You can extend or retract the weapon as a bonus action once per round.

Upgrade: Nets from the Net Launcher gain a +2 bonus to hit, are immune to nonmagical damage, and affect formless creatures and creatures that are huge or larger. Additionally, you add half your level (rounded down) to the AC and Strength check DC of nets from the Net Launcher.

Shuriken Arm

Allows you to hide shurikens inside your arm. Shurikens are statistically identical to darts, unless stated otherwise. You can draw shurikens to throw from your shuriken arm as free actions, and as an action you can load or remove up to 8 shurikens into the Shuriken Arm, which can store up to 8 shurikens.

Upgrade: Shurikens fly back to your hand after you throw them, possibly hitting the target on the return as well. Make the attack roll twice against targets of your shurikens, rolling the damage roll on each hit, but additional effects only get applied on the first hit. Alternatively, you can make the second attack roll against another target within 5 feet of the original target. The shurikens gain a +1 bonus to hit and to damage rolls.

War Weapon

Prerequisite: Main Arm

Allows you to hide a one handed retractable bludgeoning or piercing weapon inside your arm. You deal 1d8 + Strength modifier bludgeoning or piercing damage with this weapon (damage type depends on the weapon) on a hit. You can extend or retract the weapon as a free action once per round.

Upgrade: On a hit, you can use a bonus action to knock the target prone. Additionally, the War Weapon gains a +1 bonus to hit and to damage rolls.

Back

Active Camouflage

Gain advantage on all Dexterity (Stealth) checks.

Upgrade: While you aren’t moving or taking actions, you cannot be detected except by magical means, or creatures with Keen Smell or a similar trait, or blindsight. (Your position can still be determined by creatures and objects colliding against your form)

Adamantine Plate

+1 to AC and +1 to Constitution. Cannot increase an ability score above 20.

Upgrade: Additional +1 to AC. Any critical hit against you becomes a normal hit.

Automatic Potion Dispenser

Allows you to store tiny consumable items roughly the size of a potion inside your back. As an action you can load or remove up to three tiny consumable items (like a potion) into the Automatic Potion Dispenser, which can store up to three tiny items. As a reaction to taking damage, you can consume a tiny consumable item of your choice inside your Automatic Potion Dispenser. You can alternatively hide up to three tiny items that aren’t consumable, but are roughly the size of a potion or smaller, inside your Automatic Potion Dispenser instead, but you can't consume them as a reaction to taking damage. Additionally, a number of times per long rest equal to your proficiency bonus, you can cast the healing elixir spell without expending a spell slot.

Upgrade: You no longer need to expend your reaction to consume a tiny consumable item of your choice inside your Automatic Potion Dispenser as a result of taking damage. However, only once per long rest can you consume a tiny consumable item of your choice inside your Automatic Potion Dispenser as a result of damage reducing you to 0 hit points but not outright killing you.

Backup Power Bank

Prerequisite: 9th level or higher

You have magical energy stored in a Backup Power Bank in your back that has one charge. As a bonus action you can expend a charge to regain one use of a feature that you regain uses of when you finish a short rest. You can also expend a charge as an action to reduce your exhaustion level by 1 (to a minimum of 0). Additionally, when you take the attack action, you can expend a charge to be able to manifest ammunition made of energy for any ranged weapon you are holding whenever you make an attack with it until you finish a long rest. The ammunition deals force damage on a hit. You regain all expended charges when you finish a long rest.

Upgrade: The Backup Power Bank has two charges instead of one. As a bonus action you can expend a charge to regain one use of a mechromancer feature that you regain uses of when you finish a long rest. The ammunition made of energy also has a +1 bonus to hit and damage rolls.

Extra Arms

You have an additional pair of mechanical arms that you can use to cast spells, wield weapons, and hold and manipulate objects with. When you take the attack action on your turn, you can make one additional weapon attack with a light weapon you are wielding in your extra arms as a bonus action.

Upgrade: You gain your choice of +1 to AC, or +1 to Strength and your maximum for Strength is increased by 1. The weapon used for the additional weapon attack you can make with your extra arms no longer requires the light property. You also count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

Flanking Shield

You do not grant advantage to enemies due to Flanking. Also, you gain your choice of +1 to AC, or +1 to Constitution and your maximum for Constitution is increased by 1. You can change which option you choose when you requip this graft.

Upgrade: Your Flanking Shield extends out from your back and you gain half cover in up to three directions of your choice. At the start or end of each of your turns, you can change the directions the cover is facing. Additionally, as a reaction to a hostile creature you can see moving 5 feet or more, you can change the directions the cover is facing.

Flares

As a reaction to being targeted by an attack, spell or ability, you can deploy 4 magical flares. Roll a d6, on a 1 or a 2, the triggering attack, spell or ability is unaffected, on a 3 or higher, the triggering attack, spell or ability destroys one of the flares instead of affecting you. Each flare remains until the end of your next turn, or until it is destroyed. While any flares remain, whenever you are targeted by an attack, spell or ability, roll a d6. On a 1 or a 2, the triggering attack, spell or ability is unaffected, on a 3 or higher, the triggering attack, spell or ability destroys a flare instead of affecting you. You can use this feature once per long rest. With each flare's destruction, the remaining flare(s) strengthen, hence the die doesn't change with the destruction of a flare.

Upgrade: You can deploy 8 magical flares and you roll a d10 instead. You can use this feature twice per long rest.

Halo Momentum Disc

+10 feet of movement. You may switch a falling limitation ability on or off as a bonus action. You can only fall up to 30 feet per round with the falling limitation ability active, even when unconscious, and you always land safely. Alternatively, you may switch it on as a reaction to starting to fall more than 5 feet.

Upgrade: Additional +10 feet of movement. You may switch the falling limitation ability on or off as a free action, even during other creature's turns or immediately before you hit the ground. Additionally, while the falling limitation ability is active, for every 2 feet you fall vertically, you can move 1 foot horizontally.

Prison Pocket

Your rear can open up to an interior space considerably larger than its outside dimensions, and its opening can stretch open up to roughly 1 foot in diameter. It can store up to 500 pounds and any items inside weigh nothing for you, not exceeding a volume of 64 cubic feet. Retrieving an item requires an action. If you unequip this graft or die, your prison pocket’s contents spill forth, unharmed. Breathing creatures inside can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.

Pain Inhibitors

Prerequisite: Chest & Back Slot, Constitution 13

While your Pain Inhibitors are active, you do not feel pain, but can still feel pressure and discomfort from things that would cause you pain. While your Pain Inhibitors are active, you are immune to the paralysed condition and you do not fall unconscious when you have 0 hit points, but you still make death saving throws while you aren't stable as usual. As a bonus action you can deactivate your Pain Inhibitors. If you are missing any of your hit points or if your hit point maximum is reduced when you deactivate your Pain Inhibitors, you can agonise. While agonising, you have advantage on saving throws against effects that would make you fall unconscious, you can add your proficiency bonus to the damage rolls of weapon attacks you make, and you can reroll one attack roll you make on each of your turns. You can decide to reroll an attack after you see the roll, and when you do, you can decide to use either roll, but must decide whether to reroll the attack or not before the DM says whether the attack hits or misses. If you are able to cast spells, you can't cast them or concentrate on them while agonising. You can agonise for 1 minute. It ends early if you reactivate your Pain Inhibitors, if you are knocked unconscious, or if your turn ends and you haven't attacked a hostile creature since your last turn or taken damage since then. You can agonise once per short or long rest. You can reactivate your Pain Inhibitors as an action.

Upgrade: You can agonise twice per short or long rest, and you can reroll up to two attack rolls you make on each of your turns while agonising. You can reactivate your Pain Inhibitors as a bonus action.
