When combined with Soul Split, this aura will cause you to regain life points equal to 10% of any damage you deal. The Vampyrism bonus also stacks with blood spells from the ancient magicksspell book such as Blood Barrage, making it possible to restore 10% percent of every successful hit, along with soul split. This makes it incredibly difficult to take down players in a PvPminigame where multiple targets can be hit at once, such as Soul Wars. This lifepoints gained are only drawn from one target at a time in both PvP and PvM situations in multi-combat areas.
