Cacophony

You create an excruciating array of noise that can be heard from 300 ft., any creature within a 20 ft. radius must make a Constitution saving throw, on a failed save a creature takes 6d8 thunder damage and is deafened for 1d10 minutes. A creature can also repeat the save at the start of each of its turns to end the effect early. On a successful save a creature takes half as much and isn't deafened.

At higher levels:

When casted using a spell slot of 5th or higher, the damage increases by 1d8 for each spell slot level above 4th.
