Life steal icon.png Life steal is an offensive stat which grants Heal power icon.png healing equal to a percentage of the damage dealt by basic attacks, including those that are modified (such as Siphoning Strike Siphoning Strike or Spellblade). It applies to abilities that trigger On-hit icon.png on-hit effects (e.g. Mystic Shot Mystic Shot, Parrrley Parrrley, Steel Tempest Steel Tempest). It does not benefit from Heal power icon.png Heal Power. Most items that deal on-hit damage benefit from life steal.

The heal is based on the post-mitigation damage dealt, or after sources of armor, magic resistance, and damage reduction are taken into account to the damage.

All champions have 0% base life steal, but it can be increased by some items, runes, and abilities.

Gold Value ​​​​​​​

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

Damage which applies life steal

Generally speaking, all Basic Attack.png basic damage applies life steal by default, regardless of subtype: Attack damage.png physical damage dealt by Basic Attack.png basic attacks, Magic damage.png magic damage dealt by Corki's Corki's Hextech Munitions Hextech Munitions basic attacks and Hybrid penetration.png true damage dealt by Camille's Camille's Precision Protocol Precision Protocol all restore health based on the damage dealt in conjunction with life steal.

For damage types other than basic damage to apply life steal, they have to be tagged as such:

Edit"Applies life steal" is a damage tag that gives an ability the property of having a damage source apply Life steal icon.png life steal like Basic Attack.png basic attack damage would.
This tag is located on some abilities that deal spell damage (e.g. Samira's Samira's Flair Flair and Inferno Trigger Inferno Trigger) and items that deal On-hit icon.png on-hit damage.

Life steal icon.png Life steal does not have a penalty for area of effect abilities and is always applied to the damage dealt at 100% effectiveness, unless otherwise specified. Unlike Vamp, the "applies life steal" tag applies life steal directly and does not Heal power icon.png heal based on damage dealt and the life steal stat. Therefore healing modifiers that affect life steal also affect abilities with the "applies life steal" tag.

Notes

  • Life steal Additive stacking icon.png stacks additively, and has no cap.
  • Spirit Visage's Spirit Visage's passive is a unique multiplicative increase. For example, if a unit had 10% life steal, the 25% increase would be calculated as: 10% × 1.25 = 12.5% life steal.
  • Life steal does not apply to damage dealt to structures.
  • Life steal applies on damage to wards after the damage is reduced to 1, restoring effectively no health.
  • Grievous Wounds icon.png Grievous Wounds reduces the health restored by life steal.
  • Blade of the Ruined King's 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 icon.png Heal Power.

  • Relevant math:
    • Sion's Sion's life steal:
      • Items = 20% 20% + 15% 15% + 15% + 12% 12% = 62%
      • Runes = 9% 9% = 9%
      • Buffs = 100% 100% = 100%
      • Life Steal Multiplier = 1.25 1.25 = 1.25
        • Sion's Sion's life steal = (62% + 9% + 100%) × 1.25 = 213.75% life steal
