Arcane Agony

A blast of arcane sigils erupt from your hands. Each hostile creature in a 60-foot cone must make a Wisdom saving throw. A creature takes 8d8 psychic damage on a failed save or half as much damage on a successful one and you are not.

After a failed save the creature is under the effect of the confusion spell until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
