A snake-like creature made of arcane energy is propelled toward a creature of your choice within range. Make a ranged spell attack against the target. On a hit, the target takes 2d6 poison damage and 2d6 necrotic damage, and the target can only take a bonus action or action (not both) until the end of their next turn.

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