Crèadho's Cacophony

You cause an eruption of cacophonous noise; such as an orchestra, an explosion or murderous screams - to emit in a 15ft radius on a point within range. 

Each create within the radius must make a wisdom saving throw against your spell save DC. 

On a failed save you take 2d12 psychic damage, are deafened, and have disadvantage on concentration checks. You can repeat the saving throw at the end of each of your turns to remove the negative effects.

On a success you take half the damage, and are not deafened, and only have disadvantage on the triggering damage of this spell. 

At each level above 2nd, the damage increases by 1d12
