Souls Intertwined

You attempt to swap the minds of two creatures you can see within range, each of which must make a Charisma Saving Throw. If only one creature fails the saving throw, that creature takes 6d10 Psychic damage.   If both Saving Throws fail, the creatures' minds are swapped for the duration, so that each creatures' memories, knowledge, instincts, and sense of self are contained in a new body. While their minds are swapped, each creature uses the other's Intelligence, Wisdom, and Charisma scores and Alignment, which could impact other statistics such as a creature's spell save DC or psi save DCs. For the purpose of supernatural effects that identify, locate, or make contact with a creature, the body that holds a creature's mind is considered to be that creature while this power is in effect.   If one of the affected creatures dies while the other still lives, the dying creature can make a choice as their mind and soul leaves their host body:

• The soul can move on to the afterlife, leaving the mind of the other creature targeted by this power permanently in a new body. Only a Wish spell or similarly powerful effect can allow a creature permanently sealed inside another's body to return to their original form.
• The soul can attempt to force their way back into their original body. Both creatures make a contested Charisma check, rerolling ties. If the dying soul wins the contest, they reclaim their old body and force the other creature's soul into the afterlife.
