Quest: Icathia's Fall grants Bami's Cinder and permits purchases of Hollow Radiance and Sunfire Aegis despite Immolate's item limit. Completing the quest converts the items obtained for it into Void Immolation, which counts as two Burn effect sources.⁶ Patch unknown

Since patch 26.12, Sunfire Aegis and Hollow Radiance can no longer be purchased after completing Quest: Icathia's Fall.⁷

With Void Immolation, Sunfire Aegis, and Hollow Radiance, all three dealt damage, but only Hollow Radiance's aura appeared.⁸

Since patch 26.10, Hollow Radiance's Immolate triggers again after a bug prevented it from triggering.⁹
