Infernal Contract

Once the devil and the creature agree to the terms of a deal, the agreement must be sealed with a contract, which the devil can produce as an action. The contract often appears in some theatrical manner; for example, it might arrive in a puff of smoke, accompanied by a fiendish cackle or an imp waving a sparkler.

Contracts take a variety of forms, with the terms of the deal written out in Infernal, and are made binding in one of several ways, ranging from a simple signature to a revolting act. Once all concerned parties perform the actions necessary to enter the contract, the deal is struck. The character who struck the deal gains the benefits of the devil's gift and is bound to pay the price.

## Breach of contract

A creature bound by an infernal contract who fails to pay the price specified in the contract immediately suffers a penalty for breaching the contract, as specified in the contract itself. Common penalties include the following:

* The creatures soul is forfeit when the creature dies (that is, the creature is reborn in the Nine Hells as a lemure).
* The creature loses all monetary wealth and property, or a powerful magic item (determined by the DM), to the devil.
* The creature grows horns, a tail, or some other devilish features that can't be removed by any means short of divine intervention (though illusions or disguises can conceal them). As long as these marks persist, the creature detects as a fiend when subjected to detect evil and good spells or similar magic.
* The creature gains a new flaw. A creature who exhibits behavior inconsistent with this flaw has disadvantage on all attack rolls, ability checks, and saving throws until the behavior changes to match the flaw.

## Voiding a contract

Voiding an infernal contract releases all parties from its terms without penalty, as if the deal never happened. Any gifts or prices revert immediately, though some contracts might leave a scar or other lasting effect.

The devil and the character who signed the contract must both agree to void the terms of the contract. As an action, the devil magically produces the contract. When both parties state their agreement to terminate it, the contract crumbles to dust and is destroyed.

Devils require compensation in exchange for voiding a contract. Some cowardly devils might be willing to void a contract in exchange for their lives, but most would rather risk death than demotion to a lower form of devil and the scorn of its peers.

A devil might be persuaded to void a contract in exchange for one of the following:

* One or more soul coins (lesser devils will often settle for three, greater devils for nine, and archdevils have no interest in such a paltry alternative)
* An exorbitant sum of gold plus the sacrifice of many humanoids in the devil's name
* A powerful artifact, such as the Hand of Vecna or the Sword of Zariel

## Contract forms

The Contract Forms table has examples of different forms of infernal contracts. The sections that follow the table describe the various contracts and the means by which they can be destroyed and voided.

### Baby dolls

The devil produces two baby dolls made of dirty rags or rotting wood. The dolls recite the deal in high-pitched voices (in Infernal) and spew blood when they are hugged. To enter the contract, the devil and the character making the deal must each hug a doll. When the contract is finalized, the devil keeps one doll and the character keeps the other.

To void such a contract, each doll must be destroyed within 1 minute of the other. Failure to destroy the second doll in the allotted time causes the first doll to re-form after 1 minute. Each doll is a Tiny object with AC 9, 9 hit points, vulnerability to fire damage, and immunity to poison and psychic damage.

### Damned Wretch

A portal opens, and a humanoid bound in chains with its eyes and mouth sewn shut stumbles through it. This individual is likely someone who breached their own infernal contract and is now paying the price. The terms of the deal are carved into the poor wretch's skin. To enter the contract, the devil and the character who made the deal carves their names into the wretch, who is then promptly banished.

Use the commoner stat block to represent the wretch, who is blinded while its eyes are sewn shut. Once the contract is signed by both parties, the wretch no longer ages or needs food, drink, air, or sleep, and it gains immunity to all damage that isn't dealt by the devil or the character who made the deal. If the wretch dies, the contract is void.

### Infernal Scroll

The devil produces a vellum scroll with the deal written on it in blood. To enter the contract, the devil and the character making the deal sign the scroll in their own blood, or that of a humanoid who has been dead for no longer than 1 minute. Immediately after it's signed by both parties, the contract vanishes to a secure location in the Nine Hells.

Burning the scroll voids the contract. It's immune to all other damage and harm.

### Lemure kiss

The devil summons a lemure with the deal printed in glowing runes on its lumpy flesh. To enter the contract, the devil and character making the deal and must kiss the lemure. When that happens, the lemure is transformed into a stone statue with the deal visible on the surface. The statue then vanishes to the depths of the Nine Hells.

The statue is a Medium object with AC 17, 50 hit points, and immunity to all damage except radiant damage. No spell can turn it back into a lemure. Destroying the statue voids the contract.

### Song of the devil

The devil produces sheet music with the deal written on it. To enter the contract, the devil and the character making the deal must sing or play the discordant song, which remains stuck in their heads until the deal is fulfilled.

Soaking the sheet music in holy water destroys and voids the contract, and causes the character and the devil to lose the ability to speak. A greater restoration spell or similar magic ends the effect on its recipient.

### Written in stone

A swell of lava oozes from a crack in the ground and quickly cools into rock. The deal appears as glowing script on the hardening lava. To enter the contract, the devil and the character making the deal must each place their left hand into the lava, which doesn't harm them, and leave a hand-shaped imprint in the stone. The slab of cooled lava then vanishes to a place of safekeeping.

If the left hands of both the devil and the character who struck the deal are severed and placed into the handprints, the hands and the contract are destroyed, which also voids the contract.

## Gifts of Damnation

Gifts of damnation are named after the benefits you can offer mortals in exchange for their soul. As the name suggests, these gifts offer mortals only short-term benefits and usually end in tragedy.

To a fiend, however, these gifts represent the powers you can gain by offering certain contracts ang gaining the power of a soul. You can choose gifts that are thematic for your character, or that you like the benefits of, provided you meet the requirements.

### Gift of Unfettered Glory

When you hit a creature with a melee attack or melee spell attack, you can add your charisma modifier to damage dealt.

### Gift of Joyous Youth

At the beginning of your turn, if you have no more remaining hit dice, you can choose to make a DC 10 charisma saving throw. On a success, you regain 1 (one) spent hit die. If you fail, you take 1d6 psychic damage.

### Gift of Unsurpassed Forture

Whenever a creature (NPC) makes an attack roll, skill check or saving throw within 20 feet, after the GM has rolled but before they have determined the result, you can use your reaction to roll a D20. If you roll 10 or higher, the attack roll, saving throw or skill check immediatly fails.

You cannot do this again until you complete a long rest.

### Gift of Liberating freedom

*Prerequisite:* 2nd level of Fiend Transformation

As an action, you can manifest a pair of leathery demonic wings. You can then use your bonus action to fly 30 feet without triggering opportunity attacks once per turn. These wings recede if you dismiss them as a bonus action, or if you are knocked unconcious. You cannot manifest your wings while wearing any armor, but should medium or light armor be made to accomodate these wings you can.

### Gift of Prodigious Talent

*Prerequisite:* 2nd level of Fiend Transformation

Choose two of your skill proficiencies. Your proficiency bonus is doubled for any ability you make that uses either of the chosen proficiencies. This ability cannot double your proficiency bonus if it is already doubled for those skills (i.e. expertise).

### Gift of Unconditional love

*Prerequisite:* 3nd level of Fiend Transformation

Whenever a creature fails a charisma saving throw due to a spell or magical ability you control, you can use your reaction to gain temporary hit points equal to 1d10 + your character's level.

You cannot do this again until you complete a short or long rest.

### Gift of Second chances

*Prerequisite:* 3nd level of Fiend Transformation

If you are reduced to 0 hit points, you can use your reaction to roll a Hit Die. If you do, your hit point total becomes the Hit Die result instead.

You cannot use this feature again until you complete a long rest.

### Gift of Unbridled power

*Prerequisite:* 4nd level of Fiend Transformation

Upon completing a short rest, you can spend 1 Hit Die and regain any number of spell slots whose total is equal to or less than the result of your Hit Dice. If you do, you suffer psychic damage equal to the number of spell slot levels you regained.

You cannot use this feature again until you complete a long rest.

### Gift of Expansive Knowledge

*Prerequisite:* 4nd level of Fiend Transformation

When you complete this contract for the first time, you learn additional spells from the cleric, warlock or wizard spell list equal to your charisma modifier. You must have a spell slot level equal to or greater than the level of each of these spells.

While you have the effects of this contract and no other contract active, you know these spells in addition to your total spells known.
