Void Immolation

Stats

Values as the League of Legends Wiki's item data lists them, for every mode; the data doesn't state their units.

Effects

• Immolate (unique): Taking or dealing damage activates this passive for 5 seconds. Deal 20 (+ 3.5% of your bonus health) magic damage every second to enemies within cr 325 (+ 100% bonus size) units, with the damage being increased to 150% against minions.
• Desolate (unique): Killing an enemy unit causes an eruption around their death location that deals 20 (+ 2% bonus health) magic damage to enemies within 350 units.³

• Icathia's Fall lets its holder buy Hollow Radiance and Sunfire Aegis despite Immolate's item limit. Completing the quest converts those items into Void Immolation, which counts as two Burn effect sources.⁴ Patch unknown
• After completing Icathia's Fall, Hollow Radiance and Sunfire Aegis can remain unlocked and both can be purchased; whether their burn damage stacks is unclear.⁵⁴

• The item description still says true damage, with the text colored blue, even though the damage type changed to magic damage in patch 26.13.⁶⁷

• The Void Immolation quest prevented purchases of Rabadon's Deathcap until patch 26.10.⁸
• The change was a nerf in most situations, though it could be better than the previous version with a particularly strong combination.⁹
