Soul Deal

Ryi's ability, Soul Deal
The spell allows a user to steal or manipulate the soul of a target, but only if the target agrees to an offering in return for their soul.
The spell has two phases, the offer, and the activation.
When the spell is cast, offering something to the target will complete phase one, however phase two will only happen once the offer has been fulfilled, the specifics of the offer can be exploited in a Monkey's Paw kind of way, but if the offer is completed, phase 2 activates and the user can access the target's soul freely.
The agreement can activate the spell in any form of communication, telepathically, verbally, written, or signed.
