Ignites an enemy champion, dealing (50 + 20 × level) true damage over time to a single target and reduces the health regeneration and the healing effects received by 50%.
Ignite is a targeted summoner spell. It deals a moderate amount of true damage over 5 seconds and reduces healing and regeneration effects on the target by 50% for the duration.
Ignite affords players an offensive utility and damage spell that scales with level. Throughout Season 2 and Season 3, it has been a popular spell among summoners for its focused and aggressive nature.
A well-placed healing reduction debuff from Ignite can severely limit the effectiveness of enemy healing items, as well as healing abilities from champions like Soraka, Vladimir, and Warwick. This also applies to lifesteal and spell vamp effects from items and abilities such as The Bloodthirster and Morgana'sSoul Siphon.
Furthermore, Ignite'strue damage pierces fully through armor and magic resist, and is not mitigated by damage reduction. This makes Ignite an effective counter to mitigation-based items and abilities like the defensive stats from Guardian Angel and Garen'sCourage.
Cleanse removes the damage over time component of Ignite, but not the healing reduction.
The healing debuff from Ignite does not reduce the amount of temporary health gained from shields like Barrier and Janna'sEye of the Storm.
Multiple uses of Ignite on the same target will not stack.
A second application of Ignite on the target will refresh the duration of its effect, but will not provide any added damage or healing reduction. Instead, the most recent placed Ignite defines the killer if the target is killed by Ignite damage.
The healing debuff from Ignite does not stack with any other abilities that apply a healing debuff, such as Miss Fortune'sImpure Shots.
When channeling a spell and you want to Ignite make sure the target is within Ignite range. If you cast Ignite while channeling a spell like Malzahar'sNether Grasp while the target is out of range of your Ignite your champion will break his/her spell channel and move towards the enemy champion to cast Ignite
