A bright silvery light flashes from your hand to a point you choose within range and erupts in a massive swirl of snow and cold winds. Each creature in a 20-foot radius must make a Constitution saving throw. On a failure, a target takes 6d6 cold damage and has its movement reduced by 10 feet until the start of your next turn. On a success, they take half as much damage, and suffers no further effects. The cold wind spreads around corners. It freezes any liquid in the area that isn't being carried.

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.
