WonderWail

With a deep inhale and a blow, hit or string of your musical instrument, an ear piercing melody resounds and vicious energy ripples out in a 40-foot-radius Sphere from where you stand at the moment of casting. Each creature in that area makes a Charisma saving throw, taking 5d8 Psychic damage and gaining the Deafened condition for 3 turns on a failed save or only half as much damage and no affliction on a successful one.

Using a Higher-Level Spell Slot. The damage increases by 2d8 for each spell slot level above 3 and the length of the Deafened extends by 1 turn.
