Tendrils of Wretchedness

From the palm of your hand an inky black tendril flies out at a creature within range. Make a ranged spell attack against the target. 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 damage increases by 1d8 for each slot level above 1st.l
