Lifesteal causes the user's attacks to heal themselves. Abilities that deal Physical Damage (except Attack Abilities) are not affected by Lifesteal. Various items and abilities provide lifesteal.
The amount of health healed by lifesteal is proportional to post-mitigation damage.
Multiple sources of lifesteal can be stacked additively, except for the Attack Modifier lifesteal sources.
