Cacophony

You summon forth a multitude of instruments and create a wave of harsh and jarring music around you. Each creature within 10 feet of you must make a Constitution saving throw. On failed save a target takes 2d6 thunder damage and is deafened until the start of your next turn.  On a successful save, the creature takes half damage, but suffers no other effect.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
