The touch of your shadow-wreathed hand can siphon life force from others to heal your wounds. As a part of casting this spell, you make a spell attack against a creature within your reach. On a hit, the target takes 3d8 necrotic damage, and you regain hit points equal to the amount of necrotic damage dealt. Until the spell ends, you can use an action on subsequent turns to repeat the attack against a creature within reach.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
