[[Vampiric]] is life leeching [[Boss Modifier]] that occurs on Champions, Bosses, and boss minions in Diablo III. This modifier allows monsters to heal themselves for a percent of the damage they deal to heroes or pets.

The amount of healing is not generally very noticeable, but it can be quite obvious when the monster has some unkillable NPCs to target, such as Tyrael or Leah or the Necromancer's skeletons, in which case some monsters become literally unkillable; capable of refilling their hit points with every single attack.
