Telepathic Scream

You unleash a telepathic scream that reverberates in the minds of creatures within 30 feet of you. Each creature of your choice in that area must make an Intelligence saving throw. On a failed save, a creature takes 6d6 psychic damage and is incapacitated until the end of its next turn. On a successful save, the creature takes half as much damage and is not incapacitated.
