Life steal

Life steal is an offensive stat that converts a percentage of the physical damage dealt to health regained. A champion's basic attack, abilities that apply on-hit effects, and abilities that modify your next basic attack all benefit from lifesteal.

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.
