Void Bolt

A bolt of black void energy lances out toward a creature within range, forming a sustained arc of necrotic energy between you and the target. Make a ranged spell attack against that creature. On a hit, the target takes 2d8 necrotic damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the initial damage increases by 1d8 for each slot level above 1st.
