Breath of The Abyss

A sphere of divine cold arises from a crevice, breaking ground, in a location you specify. Each creature in a 15-foot-radius, centered on a point within range must make a Dexterity saving throw. A creature takes 4d6 cold damage and 4d6 necrotic damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the cold damage or the necrotic damage (your choice) increases by 1d6 for each slot level above 4th.
