Cold Snap

You create a wave of frigid air that instantly freezes everything in a 30-foot radius centred on you. Each creature within that area must make a Constitution saving throw. On a failed save, a creature takes 4d8 cold damage and is frozen until the end of its next turn. On a successful save, a creature takes half as much damage and isn't frozen. A frozen creature is restrained.

The spell also freezes any objects or liquids in the area that aren't being worn or carried. A frozen object or liquid thaws after 1 minute of being expose to a source of heat, or instantly upon taking fire damage. If a nonmagical object is thawed instantly, it might be damaged by the sudden change in temperature.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
