Thor's Snap

With a snap of your fingers, sound races to a point you choose within range and then blossoms with a thunderous roar into a concussive blast of sound. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 8d6 thunder damage on a failed save and is knocked prone. On a successful save, the creature takes half as much damage and isn't knocked prone.

The sound spreads around corners. In addition, unsecured objects that are completely within the area of effect are automatically pushed 20 feet away from the center by the spell's effect, and the spell emits a thunderous boom audible out to 300 feet.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
