Cave of Trials

The Cave of Trials is a dungeon in Final Fantasy IV exclusive to the Advance release. It can be unlocked by swapping party members in Mysidia for the first time. At this time, a White Mage alerts the Elder of Mysidia of dark clouds over Mt. Ordeals, relating to an old legend. Upon entering the Mountain, the entrance to the Cave of Trials appears.

The dungeon contains eight floors and monster formations from the Sylvan Cave, Land of Summons, and Sealed Cavern. At the final floor are five weapons guarded by bosses, one for each of the five party members players who can swap out. The weapon can only be acquired if the correct member to wield it is in the party. Each of these weapons correspond to the characters who become available after the Giant of Babel to put them on-par with the rest of the group, who can acquire their ultimate weapons in the Lunar Subterrane.
