Spell vamp

Spell vamp is a magical stat that converts a percentage of the ability damage dealt to health regained. Activated abilities that do not state they "apply on-hit effects" or modify your "next basic attack" will benefit from spell vamp.[1]

Spell vamp works off of activated item effects, Smite.png Smite, and abilities, regardless of the type of damage done. It is calculated from the damage dealt to the enemy after reductions such as magic resistance, armor or effects like Unbreakable Will.png Unbreakable Will.

Ability Drain

Note: These abilities will heal the champion by a percentage of the damage dealt from their ability. These act similar to how spell vamp works, but unlike it, they have no penalty for being AoE abilties.

Notes

  • Spirit Visage item.png Spirit Visage passive effect will increase spell vamp effectiveness.
  • Abilities with natural spell vamp have their own spell vamp fully stacking with items, runes and masteries that provide spell vamp.
  • Spell vamp applies to all types of damage: magic, physical and true.
    • There is a common misconception it only applies to magic damage, which is not true.
  • Spell vamp applies to nearly everything that isn't classified as an auto-attack. This is most abilities, but also includes activated item effects(e.g. Hextech Gunblade item.png Hextech Gunblade) and Smite.png Smite.
    • On-hit damage modifiers (e.g. Siphoning Strike.png Siphoning Strike, aka "bonus" or "additional" damage), on-hit damage over time (e.g. Seastone Trident.png Seastone Trident and Toxic Shot.png Toxic Shot) and abilities that apply on-hit effects (e.g. Parrrley.png Parrrley and Mystic Shot.png Mystic Shot) are classified as auto-attacks, and will not apply spell vamp. Any physical damage dealt will trigger life steal, while any magic and true damage dealt trigger neither life steal nor spell vamp.
    • A list of champion abilities on-hit effects that trigger spell vamp can be found here.
  • Area of effect (AoE) spells only apply 33% of the listed spell vamp.
    • Fox-Fire.png Fox-Fire are classified as multiple single-target projectiles, and will apply 100% of your spell vamp.
    • Abilities with both single-target and multi-target effects, such as Mace of Spades.png Mace of Spades and Lay Waste.png Lay Waste, will apply spell vamp depending on which effect occurs. In that, full spell vamp against a single target; or 33% against multiple targets.
    • Single target abilities that apply splash damage will apply full spell vamp to the original target, and 33% to the splash damage. For example, Conflagration.png Conflagration with Blaze.png Blaze and Desperate Power.png Desperate Power.
  • Damage over time abilities (DoT) apply full spell vamp. (e.g. BrandSquare.png Brand's Blaze.png Blaze and MalzaharSquare.png Malzahar's Malefic Visions.png Malefic Visions).
  • Does not work with the reflected damage of Thornmail item.png Thornmail. It does, however, work with the reflected damage of Molten Shield.png Molten Shield and Defensive Ball Curl.png Defensive Ball Curl.
  • Healing reduction effects like Ignite.png Ignite, Executioner's Calling item.png Executioner's Calling and Morellonomicon item.png Morellonomicon reduce the health restored by spell vamp. See healing reduction for more information.

Calculations

Spell vamp is multiplied by total spell damage to determine the amount of health restored. Area of effect spells, however, only heal one-third the normal amount.

Examples: Dealing 300 single-target damage with 10% spell vamp will heal for 30. Dealing 300 area of effect damage with 10% spell vamp will heal for 10 for each enemy affected.

Trivia

The highest spell vamp value currently possible is attainable on AkaliSquare.png Akali using her Twin Disciplines.png Discipline of Might on Twisted Treeline. This requires:

  • JannaSquare.png Janna AP = (100 + 80 × 4 + 219.201 + 83.16 + 16 + 6 + 64 + 35) × (1.25 × 1.1 × 1.05) = 1217.6024438
Total Bonus AD:(110.6 + 150 + 95 + 45 + 20 + 40 + 35 + 38.25 + 14 + 171.76024438) × 1.05 × 1.1 − 110.6 = 720.54983226
Conversion: (720.54983226 / 6) + 6 = 120.09163871
Total: 126% (decimal of .09163871 dropped)
Total: 49%
  • Spirit Visage item.png Spirit Visage increases the given spell vamp, increasing the subtotal of 175% by 20%. Making the maximum spell vamp 210%.
