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 and Morgana's Soul Siphon.
- Cleanse removes the damage-over-time component of Ignite, but not the healing reduction.
- item active effect will remove Ignite entirely.
- The healing debuff from Ignite does not reduce the amount of temporary health gained from shields like Barrier and Janna's Eye of the Storm or maximum health boosts such as and Lulu's Wild Growth.
- Multiple uses of Ignite on the same target will refresh its duration and provides no stacking effect.
- The healing debuff from Ignite does not stack with any other abilities that apply a healing debuff, such as Miss Fortune's Impure Shots or Grievous Wounds.
- Casting ignite does not interrupt channeling spells, e.g. Recall or Malzahar's Nether Grasp
- The icon for Ignite shows a great resemblance to Annie's Pyromania since they are both icons of a hand holding a flame.
