Flamerus Rex

The Flamerus Rex is a monster from Final Fantasy Mystic Quest that serves as an Earth Fiend of sorts. It is found at the bottom of the Bone Dungeon, where Benjamin and Tristam challenge it to battle. It is quite powerful with a Rip Earth attack that can be quite devastating as well as many others. After it is defeated, the Crystal of Earth reverts to normal and Tristam gives Benjamin the elixir needed to rid Kaeli of poison.
