Psionic powers (Synaptic Rend.)

By awakening your laten psionic powers you can use a action to preforem. Synaptic Rend. You can use your action to unleashes a 30-foot-radius sphere of psychic energy, centered on a point you can see within 60 feet of yourself. Each creature in that area must make a DC 13 Intelligence saving throw. On a failed save, a creature takes 4d6 psychic damage and has the incapacitated condition until the end of your next turn. On a successful save, a creature takes half as much damage only.
