A blast of freezing artic air sweeps out from you. Each creature in a 15ft cube originating from you must make a Constitution saving throw. On a failed save, target takes 3d6 cold damage, and is pushed back 10ft. On a successful save the creatures in the 15ft cube only take half damage.

In addition, unsecured liquid that are within the area of effect are automatically frozen by the spell's effect, and the spell emits a bellowing wind audible up to 100ft.

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.
