You attempt to tear a part of a creature's life away from them, gaining the vitality that they lost. Make a ranged spell attack against the creature you target. Upon hitting the creature, you deal 2d6 necrotic damage to the target, and heal half of the damage dealt rounded down.

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 1st.
