Cacophonous Burst

You call forth a small rent in the fabric of reality that lets the raw energy of the Elemental Chaos explode into existence with a thunderous burst of sound and light. Select a target within range then roll 1d8 to determine damage type. Each creature in a 5ft radius burst / 10 ft cube, takes 1d4 damage, and makes a constitution save, becoming deafened until the start of it's next turn on a failure.

At level 5 creatures who fail their save are blinded or deafened until the beginning of their next turn instead.
At level 11 and after, creatures who fail their save are blinded and deafened until the beginning of their next turn.
At level 17 and after, creatures who fail their save are blinded and deafened until the beginning of your next turn.
