Arissa's Cold Snap

You snap your fingers in the direction of a point you choose within range and a howl burst of frigid air blossoms into an explosion of absolute cold. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 cold damage on a failed save, or half as much damage on a successful one.

The cold spreads around corners. Non-magical liquids caught within the blast freeze instantly.

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.
