Each creature in a 20-foot-radius, 40-foot-high cylinder must make a Dexterity save. A creature takes 2d8 bludgeoning and 4d6 cold damage on a failed save, or half on a success. Additionally, the area is difficult terrain until the end of your next turn.

At Higher Levels: The bludgeoning damage increases by 1d8 for each slot level above 4th.
