Eternal Mayhem

You pull your hands back and push a psychic wave forward in a 90 ft cone. Each creature in this area must make an Intelligence saving throw or take 9d6 psychic damage and hallucinate until that creature has taken 60 damage on a failed save, or half as much and not hallucinate on a success. While hallucinating, the creature sees its allies as enemies, and enemies as allies. All creatures when hallucinating have an armor class of 10 and have a vulnerability to all damage.
