Ignite is a targeted summoner spell that deals true damage over a duration, applying Grievous Wounds icon Grievous Wounds on the target, and revealing them for the duration.


  • Ignite 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 Ignite to fall out of favor among all but the most aggressive roles and weakening aggressive champions and strategies overall. In Season 9 Ignite 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 Ignite can severely limit the effectiveness of enemy healing items, as well as healing abilities from champions like SorakaSquare Soraka, AatroxSquare Aatrox, VladimirSquare Vladimir, VolibearSquare Volibear, and WarwickSquare Warwick. It is considered a direct counter to Dr. MundoSquare Dr. Mundo, SorakaSquare Soraka, AatroxSquare Aatrox and SwainSquare Swain because they are reliant on their healing-based abilities and ultimates. The healing reduction debuff also applies to life steal and spell vamp effects from items and abilities such as The Bloodthirster item The Bloodthirster and MorganaSquare Morgana's Soul Siphon Soul Siphon.
  • It should be noted that Ignite Ignite deals true damage and therefore cannot be mitigated by any form of damage reduction, although shields and invulnerability will absorb the damage.

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's damage scales with the user's level.
  • Cleanse Cleanse removes the damage-over-time component of Ignite Ignite, but not the healing reduction.
  • Ignite Ignite's healing debuff does not reduce shields or health boosts like JannaSquare Janna's Eye of the Storm Eye of the Storm or LuluSquare Lulu's Wild Growth Wild Growth.
  • Multiple uses of Ignite Ignite on the same target will refresh its duration and does not provide a stacking effect.
  • Ignite Ignite does not stack with any other abilities that apply Grievous Wounds icon Grievous Wounds, such as VarusSquare Varus' Hail of Arrows Hail of Arrows.
  • Taking damage from Ignite interrupts Recall as of patch V5.3; other channeled abilities are unaffected.
  • The cooldown of this spell can be reduced by summoner spell cooldown reduction.

  • The icon for Ignite Ignite shows great resemblance to AnnieSquare Annie's Pyromania Pyromania since they are both icons of a hand holding a flame.
  • Ignite Ignite and Chilling Smite Chilling Smite (and Mark Mark on Howling Abyss) are the only summoner spells that deal direct damage to enemy champions.
