Chilling Tempest

A blizzard of thunder and ice pounds the air in a 20-foot-radius sphere, centered on a point within range. Each creature in the sphere must make a Constitution saving throw. A creature takes 2d8 thunder damage and 4d6 cold damage on a failed save, or half as much damage on a successful one.

Hailstones turn the storm's area of effect into difficult terrain until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the thunder damage increases by 1d8 for each slot level above 4th.
