Vampiric Touch

The shadow of undeath wraps around your hand. Make a melee spell attack against a creature within your reach. On a hit, the target takes 3d6 necrotic damage, and you regain hit points equal to half the necrotic damage dealt. Until the spell ends, you can make the attack again on each of your turns as an action. This spell draws from the same fracture in death that created the Pale Lords. The sensation is intoxicating; a warm, vital rush that fills you from the fingertips inward. Warlocks who use this spell frequently report growing to crave the sensation. The GM may call for a Corruption check after repeated use.
