Void Burst

A small explosion of aetherial energy explodes outward from a point within range. All creatures within a 10-foot radius must make a Dexterity saving throw, taking 3d6 force damage on a failed save, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, it deals an additional 2d6 force damage for each slot level above 1st.
