Blast Wave

You launch a small black stone to a point of your choice, and it explodes as a sonic burst. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. On a failed save, a target takes 6d6 thunder damage and is thrown out of the radius (They are pushed the direction that would get them out the fastest). On a successful save they take half damage and aren't moved.

Any glass object caught within the radius instantly shatters.

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.
