Concussive Blast

You project a deadly wave of sound towards a creature within range. The target must make a Constitution saving throw. On a failure, the target takes 4d10 thunder damage and is stunned until the end of your next turn. On a success, the target takes half as much damage and is not stunned.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 for each slot level above 3rd.
