A dark streak flashes from your pointing finger to a point you choose within range, and then blossoms with a low roar into an explosion of cold fire. Each creature in a 20 foot radius sphere, centered on that point, must make a Dexterity saving throw. A target takes 3d6 cold damage and 3d6 necrotic damage on a failed save, or half as much damage on a successful one. The dark fire spreads around corners.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the cold damage or the necrotic damage (your choice) increases by 1d6 for each slot level above 3rd.
