Concussion

You send out a concentrated concussive wave of sound at a creature within range. Make a range spell attack against that creature. On a hit you deal 1d8 thunder damage to them as they are ravaged by soundwaves. Creatures that have advantage on perception checks relying on sound or those that have the echolocation trait must make a Constitution saving throw. On a failure they are deafened for the next round.

This spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
