Shadowy beam of necrotic energy shoots from your outstretched fingers while you hold your arm pointing at a creature within range. Make a ranged spell attack against the creature to drain life energy from it. On a hit, the target takes 3d10 necrotic damage and you regain hit points equal to half the amount of necrotic damage dealt. Until the spell ends, you can make the attack again on each of your turns as an action.
At higher levels: When you cast this spell using the spell slot of 6th level or higher, the damage increases by 1d10 for each slot level above 5th.
