Concussive Blast

The small sphere required for the spell streaks from your grasp to a point within range, whereupon it detonates in an explosion that can be heard for 300 feet. Every creature within 10 feet must make a Constitution saving throw or take 4d8 thunder damage and be pushed 10 feet away from the point you chose. On a successful save, a creature takes half damage and isn't pushed.
At Higher Levels. When you cast this spell with a spell slot of 4th level or higher, the damage increases by 1d8 for each spell level above 3rd.
