Cerebral Blast (HB)

Your mind unleashes a blast of overwhelming mental force in a 30-foot cone. Creature in the area of this spell must make a Strength saving throw. On a failed save, a creature takes 5d8 psychic damage and is pushed 20 feet directly away from you in a line, then falls prone. On a success, creatures take half as much damage, remain in place, and don't fall prone.

At Higher Levels: When you cast this spell using a spell slot of 4th-level or higher, the psychic damage increases by 1d8 for each spell slot level above 3rd.
