Avalanche

A bright streak flashes from your pointing finger to a point you choose within range where a heavy blanket of snow and ice falls from the sky. Each creature in a 20-foot-radius cylinder centered on that point must make a Dexterity saving throw. A target takes 4d6 cold and 3d6 bludgeoning damage on a failed save, or half as much damage on a successful one.

The area is considered difficult terrain until the snow melts. Creatures with burrowing speeds can tunnel through the snow unrestricted.

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.
