Chaotic Possesion

The power of Chaos flows through you and using this energy you are able to posses and in turn control others. To use this spell you must touch a creature and they must make a WIS save against you spell DC + your WIS. Any fiend, undead, or other with close connection to Chaos or fiends. On a failed save you are now in complete control of the being until they succeed the saving throw (which they make at the end of their turn) or either you or them drop to 0 hp or get knocked out. While in control during their turn you are able to control their action(s), bonus action, and movement, as well as any reaction or attack of oppurtunity. This spell automatically fails if the creature is already being controlled or has no free will.
