Devil's Deal

You call upon some demonic power and bind the target with a contract. 

You must shake the hand of one creature that you can see, or convince them to sign a contract written on a piece of hide from a devilish/trickster animal (DM's discretion). If the target is unwilling, they must succeed in a wisdom saving throw. On a failed save, the target becomes charmed by you for the duration. The charmed target is incapacitated and unaware of its surroundings, though it can still hear you. If the target is willing, they are not incapacitated though they are still charmed by you for the duration of the spell.

When the spell is cast the spellcaster must state the conditions and requirements of the contract out loud to where the target can hear them, and it must be able to understand your language for the deal to take root. If not, the spell has no effect. 

Upon the completion of the spell, the target is bound to the spellcaster through a soul bond, allowing the spellcaster to communicate with the target once per day with the spell Sending. In addition to this, if the target were to perform any action that was a violation of the conditions of the contract, or attempt a loophole to prematurely end the contract, they suffer physical damage equal to the severity of the infraction. The damage leaves no physical wounds, signs, or indications that the target has been hurt. (DM's discretion and/or player input if cast by a player)

1. Minor infraction- 1d6 physic damage
2. Mild infraction- 2d6 physic damage
3. Moderate infraction- 3d6 physic damage
4. Moderate severe infraction- 4d6 physic damage
5. Severe infraction-  5d6 physic damage

The spell lasts until the deal's conditions have been met on both ends.

A Remove Curse or Greater Restoration spell cast on the target breaks the deal without causing the target any adverse harm. However, the spellcaster is aware that the spell has been broken.
