Disrupting Pitch

Choose one creature within range and assault it with unstable pitch. The target must make a CON save, taking 3d8 thunder damage and becoming deafened for the duration on a failed save, or half damage only on a success. While deafened this way, it has disadvantage on concentration checks and cannot benefit from effects requiring it to hear commands, music, or instructions. It repeats the save at the end of each turn.
