Ignite is a targeted summoner spell that deals a moderate amount of true damage over 5 seconds and reduces healing on the target by 40% for the duration, revealing them for the duration.


Ignite.png Ignite affords players an offensive utility and damage spell that scales with level. Throughout Season 2 and Season 3, it was a popular spell for creating a greater margin for a kill in an all-in attack, particularly useful on burst-centric champions such as mages or assassins, where a kill combo typically treads the boundary of finishing a full-health or nearly full-health opponent. In the second half of Season 3, it began to see increasing use in the support role for playstyles prone to aggressive all-ins. The changes to Heal.png Heal and Exhaust.png Exhaust in Season 4 have provided powerful tools to defend against all-ins, causing Ignite.png Ignite to fall out of favor among all but the most aggressive roles and weakening aggressive champions and strategies overall.

A well-placed healing reduction debuff from Ignite.png Ignite can severely limit the effectiveness of enemy healing items, as well as healing abilities from champions like Soraka Soraka, Vladimir Vladimir, Volibear Volibear, and Warwick Warwick. It is considered a direct counter to Dr. Mundo Dr. Mundo, Soraka Soraka, and Swain 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.png The Bloodthirster and Morgana Morgana's Soul Siphon.png Soul Siphon.

It should be noted that Ignite.png Ignite deals true damage and therefore cannot be mitigated by any form of damage reduction, although shields will take priority over health for absorbing the damage.

  • The icon for Ignite.png Ignite shows a great resemblance to Annie Annie's Pyromania.png Pyromania since they are both icons of a hand holding a flame.
