Cold Snap

A swirling burst of freeze wind erupts at a point you choose within range. Each creature in a 10-foot-radius sphere centered on that point must make a Constitution saving throw. A creature takes 3d8 cold damage on a failed save, or half as much on a successful one.

The ground in the area is covered with slick ice, making it difficult terrain until the start of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
