Power Theft

Power Theft is the ability to steal other people's powers. This only works though, if the people the power is stolen from are dead. This is the passive side of Power Theft.

Thief's Will
Thief's Will is the will form of Power Theft. It only works once a day, and it will instantly steal powers from a person, granting them to the thief instead. The person the power was stolen from will momentarily lose their ability to use it, until it returns the next day. The thief will also keep their power, though.
