Life steal

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 ​​

• Life steal has a gold value of 37.5 per point.

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 40% increase would be calculated as: 10% × 1.3 = 13% life steal.
• Life steal will not work against structures and wards.
• Healing reduction effects like Ignite and Varus' Hail of Arrows reduces the health restored by life steal.
• Blade of the Ruined King's bonus damage healing is considered a drain effect, even thought it scales off life steal. This means that the healing is affected by  Heal Power.

See Healing reduction for more information.

• Runes:
  • Legend: Bloodline
  • Revitalize
• Items:
  • 1 The Bloodthirster
  • 1 Death's Dance
  • 1 Hextech Gunblade

    • Blade of the Ruined King
    • Ravenous Hydra
• Buffs:
  • Sion's Glory in Death
  • Elixir of Wrath
• Life Steal Multiplier:
  • Spirit Visage
  • Revitalize
• Relevant mathematics:
  • Sion's life steal:
    • Items = 20% + 15% + 15% + 2 × 12% = 74%
    • Runes = 12% = 12%
    • Buffs = 100% + 15% = 115%
    • Heal Multiplier = 1.3 ×  1.1 = 1.43
      • Sion's life steal = (74% + 12% + 115%) × 1.43 = 287.43% life steal
