Effect
You enter into a binding contract with a willing target, trading a piece of your power in exchange for claiming your target’s soul at the contract’s fulfillment. While the contract holds, you can’t use the spell slot or Mystic Arcanum feature you used to cast this spell, as the magical energy you would expend each day is delivered to your target instead. The spell slot isn’t regained until the terms of the contract have been fulfilled.
Choose one of the following terms to require of your target, or decide on a similarly clear term:
The pact ends when the target kills a specific creature.
The pact ends when the target dies.
The pact ends after one year.
Choose one of the following effects to grant your target:
If the target is a spellcaster, they learn three spells of 5th-level or lower from any spell list. They can cast each of these spells without expending a spell slot, and they must finish a long rest before they can cast that spell in this way again. They can also cast these spells using spell slots they have of the appropriate level.
The target’s hit point maximum is doubled; this benefit doesn’t affect hit points gained from leveling up or other effects after this spell is cast.
The target gains 50,000 gp, which this spell creates. The gold disappears, along with all goods and services purchased with it, when the contract’s terms are fulfilled.
The contract ends when its terms are fulfilled, whereupon the target’s soul appears in your hands in the form of a diamond worth 25,000 gp. If the target dies, they can only be brought back to life if this diamond is used as the material component for a spell such as revivify or resurrection. If the diamond is destroyed or consumed by another spell, the soul is destroyed.
The contract can’t be ended prematurely, even if both parties desire it, except by a wish spell.
