Dissonant Wave

A burst of Psychic energy emanates from your hand or head in a 15-foot cone hitting everyone in that area with psychic whispers. Each creature in that area must make a Wisdom saving throw. On a failed save, a creature takes 3d6 Psychic damage. On a successful save, a creature takes half as much damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
