* The [[File:Molten_Battleaxe_Icon.png|35px]] Molten Battleaxe's design is most likely based on the Molten Master costume. Of course due to the weapon being an axe, the Molten Master won't be able to wield it.
* The wallpaper shows the Molten Master wielding the [[File:ScreenShot00777Molten Tome Icon.png|35px]] Scorched Tome of Molten Brimstone.
* The Molten Master was once included (among other stuff) in a DLC called the Heartwarming Bundle as a celebration for Valentine's Day 2018. Sadly, there no heart-shaped eyes for the actual costume like the DLC's wallpaper depicted.
