Bone Arrow

A oozing boney arrow streaks toward a target within range and bursts in a barrage of splints. Make a ranged spell attack against the target. On a hit, the target takes 1d6 piercing damage and 1d4 necrotic damage at the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the necrotic damage increases by 1d4 for each slot level above 1st.
