Life steal is an offensive stat that converts a percentage of the physical damage dealt by a champion's auto attack (and the small number of abilities that proc on-hit effects as noted below) to health regained.

Life steal is calculated from the actual damage done to an enemy, after armor and all other forms of damage reduction. Almost all champions have 0% base life steal. It can be increased with items, runes, masteries, and some champion abilities.
