* With the introduction of [[Firelord Adept]], the Adept now has two fire-themed costumes which is the first time a hero has two costumes based on the same element ''(This title can also be applied to the Lavamancer too with [[Molten Juggernaut]] and [[The Zombiemancer]] costumes since the latter came in the same update as the Firelord Adept)''. Despite that, both costumes has some differences in their secondary theming - the Doomfire Regalia took a dark and demonic direction, while the Firelord Adept went with a regal and godly direction.
* Within in-game files, this costume was internally known as ''"Skull Mage"''.
