Ignite is a unit-targeted summoner spell that deals true damage over the duration and applies healing reduction as well as granting sight of the targeted enemy champion.


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 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. Note that Heal Heal will absorb a larger portion of Ignite Ignite's damage at lower levels.


  • 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 healing abilities from champions like Soraka OriginalSquare Soraka, Aatrox OriginalSquare Aatrox, Vladimir OriginalSquare Vladimir, Volibear OriginalSquare Volibear, and Warwick OriginalSquare Warwick. It is considered a direct counter to Dr. Mundo OriginalSquare Dr. Mundo, Soraka OriginalSquare Soraka, Aatrox OriginalSquare Aatrox and Swain OriginalSquare 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 item Death's Dance and Aatrox OriginalSquare Aatrox's World Ender World Ender.
