Crack of Thunder

Choose a creature within range; the air around that target collapses inward, making a loud cracking noise. They must make a Constitution saving throw; on a failure, they take 2d12 thunder damage and are Stunned until the end of their next turn. If they succeed, they take no damage and are not stunned. The noise is entirely contained within the creatures space.

At Higher Levels: This spell's damage increases by 1d12 for every slot level above 2nd.
