Revision 3

Secret Dungeons are optional high-difficulty dungeons hosted somewhere in the world of Final Fantasy Resonance. Square Enix named them on August 24, 2026 among the game's completionist elements. They stand apart from the main story: nothing in the main scenario runs through them, and Square Enix positions them as a difficulty test for players who go looking for one.

Confirmed Details

Dungeons and Magicite

Magicite, the material behind Vision Awakening, is found in dungeons lying within treasure chests. As of October 11, 2026, Square Enix has not said whether the secret dungeons in particular hold any, so treat that connection as unconfirmed until it is stated.

Where They Sit in the Optional Layer

Secret Dungeons are one of four completionist tracks Square Enix detailed on August 24, 2026, alongside Mighty Foes, the Gilgamesh encounters, and Ultima Weapon. They join an optional layer that already includes the Colosseum, the Twelve Legendary Arms, and locations reachable only by airship, all indexed at Side Content and Endgame.

Square Enix confirmed on September 3, 2026 that Sephiroth can be found and challenged somewhere in the game for a special reward. It has not said that he waits in a secret dungeon, or in any other named track, and he is not a Vision; he is covered under Side Content and Endgame.

Not Yet Detailed

As of October 11, 2026, the number of secret dungeons, where they sit on the map, how they are found, what guards them, what they award, and whether any of them are among the airship-reachable locations all remain unpublished.
