Dark Force

A mysterious black orb appears in the center of a point you choose within range, which then crackles and rapidly expands to fill a 10-foot radius sphere. Each creature in the area of the sphere must make a Dexterity saving throw. A target takes 2d6 force damage and 2d6 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 2nd level or higher, the amount of both the force and necrotic damage caused by the spell increases by 1d6 each for each level above 1st.
