Lifesteal

Lifesteal allows the attacking unit to gain Health when damaging an enemy, which includes any attack modifier with physical damage or magical damage. The lifesteal ability can be gained via items, passive abilities or the auras of other units.

The amount of health a unit gains from lifesteal is calculated by a percentage of the actual damage done to the attacked unit. This means it does not heal for overkill damage dealt on a unit, so if an attack's damage exceeded the target's current health and killed it, the heal is based on the target's remaining health.
