Using dark magic, you siphon the life force of a nearby creature. Make a ranged spell attack against a target creature within range. On a hit, the creature takes necrotic damage equal to 3d6 + your spellcasting ability modifier, and you regain hit points equal to half the amount of necrotic damage dealt.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
