Dissonant Chord

You emit a terrible, piercing note. The note pulses in the air, radiating like a shockwave. It slams into nearby creatures and rattles loose objects.

Creatures, other than you, in an area of 10 feet around you for initial wave and 11-20 feet for the secondary wave, then 21-30 feet for the third wave must make a Wisdom saving throw or take 3d8 force damage for initial wave, 3d6 force damage for the secondary wave and 3d4 force damage if in the third wave and are deafened, or half as much damage and not deafened on a successful save.

At Higher Levels. When you cast this spell using a spell slot of 4th or higher level, the damage increases by 1d8 for initial damage, 1d6 for secondary wave damage and 1d4 for third wave damage for each slot level above 3rd.
