Adder's Strike

A snake-like shadow is propelled toward a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 4d6 necrotic damage, and the target cannot take a reaction until the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
