Life stealing

Life Stealing (aka "vampirism") is a weapon feature. It means that every time the weapon hits a foe on top of the normal damage it will steal the specified amount of health from the foe and heal the attacker for the same amount.

To balance the Life Stealing, vampiric weapons always come with -1 Health Regeneration. This means you only benefit from the Life Stealing if you attack fast enough. While you don't use a vampiric weapon you better switch to an other Weapon Set.
