Boombust

You create a burst of thunderous sound that can be heard up to 200 feet away. Each creature within range, other than you, must succeed on a Constitution saving throw. A creature takes 1d12+1 thunder damage on a failed save and become frightened for the duration, or half as much damage on a successful one.

The spell’s damage increases by 1d12+1 when you reach 11th level (2d12+2), and 17th level (3d12+3).
