Avalanche Burst

You cause a cascade of stone and snow to crash down in a 30-foot-high, 10-foot radius cylinder at a point you choose within range. Each creature in the area must make a Dexterity saving throw, taking 3d6 bludgeoning damage on a failed save, or half as much on a successful one. Additionally, the ground in that area becomes difficult terrain until cleared away. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
