Spell vamp

Spell Vamp is a magic stat. The Spell Vamp works as the magic counterpart of Life Steal, but instead of absorbing life from physical attacks, it absorbs life from champion abilities. It works off of items, summoner spells, and abilities that deal magic damage. Spell Vamp is calculated from the damage dealt to the enemy (after Magic Resistance).
