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.

Overview

Ignite Ignite provides 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 Heal and Exhaust Exhaust in Season 4 have 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.

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, VladimirSquare Vladimir, VolibearSquare Volibear, and WarwickSquare Warwick. It is considered a direct counter to Dr. MundoSquare Dr. Mundo, SorakaSquare Soraka, 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 will take priority over health for absorbing 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 activate 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.
