Mt. Gagazet
Monster Arena Fiend Listing

The following fiends can be found along Mt. Gagazet and in the caves.

Capturing all of the fiends at Mt. Gagazet will unlock another fiend named Catoblepas in the Area Conquest section of the Monster Arena. Speak to the Monster Shop owner after you have captured each of them to add the fiend to the Area Conquest section in the menu.
