Draining Touch

Dark energy come to your hand to drain the life energy from a creature you try to touch. Make a ranged or melee spell attack against the target. On a hit, the target takes 1d8 necrotic damage, and you gain temporary hit points equal to half the amount of damage dealt for 1 minutes. This spell has no effect on undead or constructs.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
