Dark Vessel (5e Class)

Dark Vessel

Seduced by the power that lies on the lower planes, some individuals seek for fiends, in order to make agreements, pacts. While some just exchange their souls or servitude for magical knowledge, others grant to the fiends the opportunity to leave their planes for some time, using their bodies as vessels for the fiendish spirits.

While the fiends enjoy the freedom given by the material plane, these pact makers, called Dark Vessels, gain the power of these fiends, mutating their bodies to gain the power of these powerful entities. This is a dangerous pact, since sometimes a fiend will take advantage of the body and seek to take control over it. But for such power, many believe to be a price worth paying.

Creating a Dark Vessel

When creating your dark vessel, think about this: What is your character doing with their power? Are they carrying out the fiendish legacy by slaughtering the innocent, or are they using their potential to rain judgement upon the wicked? What was their life like before they gained their new strength?

Dark Binding

Starting at 1st level, you can forge pacts with creatures from the hell and from the abyss, allowing you to summon these creatures to inhabit your body for some time.

During a short or a long rest, you can draw a summoning circle on the ground around you, made out of your blood. You must meditate for 1 hour inside this circle (doing so during a short rest prevents you from getting the benefits of it). You gain the benefits of the dark binding after finishing the rest.

You must contact a fiendish entity, and forge a bond with it, which requires you to succeed on a Persuasion, Intimidation or Deception check against it. On a success, the fiend is bound to you, which leaves a mark of the personal glyph of that fiend on a chosen part of your body. You can have a number of bound fiends equal to your Charisma modifier (minimum of 1). You can end a bind with a fiend as an action.

After finishing the dark binding, you lose a number of hit dice equal to the hit dice of the fiend bound to you. If you have less hit dice than the amount of hit dice the fiend has, roll a number of d10 equal to the amount of hit dice the fiend has minus the number you have. You take damage equal to the amount rolled.

Your starting bound fiend is a creature with a CR of 1/4 or lower of your choice.

In addition, you learn how to speak, read and write in infernal and abyssal.

Fiendish Possession

Starting at 1st level, you can use your action to touch the fiendish glyph to summon the spirit of that fiend to your body. When you do so, your body starts to mutate, assuming the form of the chosen creature.

When you are possessed, you choose if your equipment disappear for the possession duration or if it remains in your body. You retain your Intelligence, Wisdom and Charisma scores, saving throws, proficiency bonus, skills and class features. You gain all the creature's trait.

You assume the fiend hit points (but not the Hit Dice). When you revert to your normal form, you return to the number of hit points you had before you transformed. If you drop to 0 hit points, you revert to your normal form, and any excess damage carries over to the normal form. In addition, you can't be possessed again by that demon until you finish a long rest.

When you use your action to summon the fiend, it will try to take over the control from you. You must succeed a Charisma saving throw against a DC equal 10 + the fiend Charisma modifier, or lose control to it. While out of control, the DM choose what actions it takes. You can, at the start of each of your turns, try to regain your control. You can't be controlled by that fiend again for the next 24 hours. Knowing the true name of that fiend give you advantage on this roll.

You can dismiss the summoned fiend as an action. Your fiendish form can't regain hit points by any means.

Spellcasting

Spellcasting

By the time you reach 2nd level, you have learned to use the magical power of pacts to cast spells, much as a warlock does.

Spell Slots

The dark vessel table shows how many spell slots you have to cast your spells of 1st level and higher. To cast one of these spells, you must expend a slot of the spell's level or higher. You regain all expended spell slots when you finish a long rest.

For example, if you know the 1st-level spell Animal Friendship and have a 1st-level and a 2nd-level spell slot available, you can cast Animal Friendship using either slot.

Spells Known of 1st Level and Higher

You know two 1st-level spells of your choice from the warlock spell list.

The Spells Known column of the dark vessel table shows when you learn more dark vessel spells of your choice. Each of these spells must be of a level for which you have spell slots. For instance, when you reach 5th level in this class, you can learn one new spell of 1st or 2nd level.

Additionally, when you gain a level in this class, you can choose one of the dark vessel spells you know and replace it with another spell from the warlock spell list, which also must be of a level for which you have spell slots.

Spellcasting Ability

Charisma is your spellcasting ability for your dark vessel spells, since your magic draws on your attunement to nature. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a dark vessel spell you cast and when making an attack roll with one.

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

Spell attack modifier = your proficiency bonus + your Charisma modifier

Taint

Starting at 2nd level, the constant possession by fiends on your body started to corrupt you, changing and deforming your body. You have two such taints when you first gain this feature, and you can choose more at 5th, 9th, 13th and 17th levels. Also, whenever you gain a new taint, you can replace one old taint for a new one.

You can manifest only three of your taints at the same time. You loose the ability to manifest one taint for each fiend you become unable to summon.

When you gain the Unholy Bargain feature, you can manifest all your taints at the same time, while your Unholy Bargain fiend still is alive.

Paths of Corruption

Starting at 3rd level, you choose a path of corruption, that enhance your abilities to connect with fiends. You can choose the Abyssal Path, the Infernal Path or the Redeemed Path. The path you choose grants features at 3rd, 5th, 7th, 14th and 18th level.

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.

Corrupt Transformation

At 6th level, you can choose one attack of any bound form you have and use it while in your normal form. At 11th level you can choose any action that can be taken by a bound creature and use it while not possessed. At 15th level, you can choose one damage resistance.

Unholy Bargain

Starting at 10th level, you can now struck a deal with a powerful entity. You can choose a single creature with a CR equal to half your level (rounded up) to forge a Dark Pact with. You can only have one such creature at the same time bound to a pact.

Summoning and hosting this fiend is extremely taxing on you, and it can inhabit your body for a number of minutes equal to your level in this class, or until you dismiss it as an action. After finishing the summoning, you must make a Constitution saving throw with a DC equal to the fiend's CR, or suffer one level of exhaustion.

At 20th level, you can forge a dark pact with a even more powerful creature. You can now choose a single fiend with a CR equal to your level in this class. The possession lasts for 1 hour and you no longer suffer exhaustion from it.
