Void Bolt

A shadow of darkness streaks toward a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 3d8 necrotic damage, and the next attack roll made against this target before the end of your next turn has advantage, thanks to the dark aura surrounding the target until then.

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