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 and Exhaust in Season 4 have 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.
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. It is considered a direct counter to Dr. Mundo and Swain because they are both reliant on their healing-based ultimates. The healing-reduction debuff also applies to life steal and spell vamp effects from items and abilities such as The Bloodthirster and Morgana'sSoul Siphon.
