You form a ball of light containing sediment and lob it, as if it were a baseball, to a point you choose within range, with the sound of a whistling bird it then bursts into a firework-like explosion of force. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 force damage on a failed save, or half as much damage on a successful one.

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.
