Life steal (LS) is a stat that restores health to the attacker based on a portion of damage dealt from a basic attack, including attacks that are modified by effects or abilities (such as 
Nasus' 
Siphoning Strike or Spellblade). Life steal works for abilities that apply on-hit effects such as 
Mystic Shot and 
Parrrley, but not with item actives (e.g. 
Blade of the Ruined King). Usually, on-hit effects do not interact with life steal.
Life steal is calculated from the effective damage dealt by the attack after modifiers and mitigation (i.e. armor).
All champions have 0% base life steal, but it can be increased with items, runes, and by some champion abilities.
Gold Value

Notes
- Life steal stacks additively, and has no cap.
- Spirit Visage's passive is a unique multiplicative increase. For example, if a unit had 10% life steal, the 30% increase would be calculated as: 10% × 1.3 = 13% life steal.
- Life steal will not work against structures and wards.
- Grievous Wounds reduces the health restored by life steal.
- Blade of the Ruined King's bonus damage healing is considered a drain effect, even though it scales off life steal. This means that the healing is affected by Heal Power.
