Passage of the Eidolons

The Passage of the Eidolons is a location in Final Fantasy IV. Its caverns links the Underworld to the Feymarch, land of Eidolons. The cave is littered with many lava-filled pits, which will damage the entire party if stepped on. Rosa can prevent this damage by casting Float on the entire party. The spell will need to be recast whenever a new floor is reached. On the third basement level of the Passage, a blue prism awaits that will teleport the party to the Feymarch.

The Passage of the Eidolons is a completely optional dungeon and as such may be accessed at the player's leisure. It is only accessible after the airship Falcon is obtained, though the player may wish to level up their party first in order to be prepared for the tough monsters that nest in the cave.
