Ignite is a unit-targeted summoner spell that burns an enemy champion for a few seconds, dealing periodic true damage, applying healing reduction, and revealing the target over the duration.


  • Each tick deals 14 − 82 (based on level) true damage.
  • Ignite deals its first tick of damage at [0 to 0.264] seconds after the cast, based on how soon the first character stat update tick after the cast occurs.
    • The last tick is thus dealt at [0 to 0.264] plus 5.28 seconds, well before the debuff's duration runs out.
  • Cleanse Cleanse removes the damage over time and Sight icon reveal components of Ignite, but the healing reduction debuff will persist.
  • Ignite deals Umbra Blades default damage, and thus will not trigger spell effects.
  • Ignite's healing debuff does not reduce shields or maximum health gains like Renekton's Renekton's Dominus Dominus or Lulu's Lulu's Wild Growth Wild Growth.
  • Ignite cannot reveal Guerrilla Warfare stealthed targets as it does not apply True Sight icon true sight.
  • Applying another cast will overwrite the existing debuff.
  • Ignite grants two stacks of Conqueror Conqueror, and one of Electrocute Electrocute and Phase Rush Phase Rush upon activation.
  • Ignite triggers Summon Aery Summon Aery on the application of its first tick.
    • Subsequent ticks cannot trigger the rune.
  • Ignite deals Hybrid penetration true damage and therefore cannot be mitigated by any form of damage reduction, although Hybrid resistances icon shields and Cosmic Radiance invulnerability effects will absorb the damage.
  • The cooldown of this spell can be reduced by summoner spell cooldown reduction.

Effectiveness comparison[]

The following table compares the effectiveness of Barrier Barrier vs Heal Heal on a target affected by Ignite Ignite.

  • Barrier Barrier will always negate 40% of Ignite's Ignite's damage if it is activated while under the effect of Ignite Ignite for at least 2 seconds.
  • Heal Heal will always negate more damage than Barrier Barrier.


  • Ignite provides players an offensive utility and damage spell that scales with level. Throughout Season 2 and Season 3, the spell was nearly ubiquitous in all lanes, as the extra kill pressure was highly valued. The changes to Heal Heal and Exhaust Exhaust in Season 4 provided powerful tools to defend against all-ins, causing Ignite to fall out of favor among all but the most aggressive roles and weakening aggressive champions and strategies overall. In Season 9, Ignite regained its original lower cooldown and is now heavily favored among supports and 1v1 kill lanes.
  • A well-placed healing reduction debuff from Ignite can severely limit the effectiveness of enemy healing items, as well as Heal power icon healing abilities from champions like Soraka Soraka, Aatrox Aatrox, Vladimir Vladimir, Volibear Volibear, and Warwick Warwick. It is considered a direct counter to Dr Dr. Mundo, Soraka Soraka, Aatrox Aatrox and Swain Swain because they are reliant on their healing-based abilities. The healing reduction debuff also applies to Life steal icon life steal, Spell vamp icon spell vamp, and Ravenous Hunter rune drain effects from items and abilities such as Death's Dance Death's Dance and Aatrox's Aatrox's World Ender World Ender.
