Vampiric blood blade

Creates a blade of blood in the caster's hand(s). The touch of your blood weapon can siphon life force from others to heal your wounds. Make a melee spell attack against a creature within your reach. On a hit, the target takes 3d6 vampiric damage, and you regain hit points equal to half the amount of vampiric damage dealt. Until the spell is dispelled, you can make the attack again on each of your turns as an action.

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 3rd.
