Breakcore

Using an experimental soulgem device you release sharp mechanical sounding music that rattles the heads of those that hear, if it was a lower volume it'd be enjoyable to some people. Each creature in a 15-foot cone must make a Constitution saving throw. A creature takes 1d6 thunder damage and suffers the Deafened condition till the start of your next turn on a failed save.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
