Boulder Toss

A boulder forms in the air in front of you, and upon performing a violent spitting action, the boulder is hurled forwards at a location within 40 ft. Each creature in a 10-foot radius sphere entered on that point must make a Dexterity saving throw. A target takes 10d6 bludgeoning damage on a failed save, or half as much damage on a successful one. In the event of a critical failure, the target is knocked prone.

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.
