Booming Voice

Your voice booms loudly in a 15-foot radius centered on the caster, anything that can hear you within this radius must succeed on a constitution saving throw or take 1d12 Thunder Damage and be deafened until the end of their next turn. If they succeed on the save, they take half damage and are not deafened.

This spell's damage increases by 1d12 when you reach 5th level (2d12), 11th level (3d12), and 17th level (4d12).
