Bonus dungeon (エクストラダンジョン, Ekusutora Danjon?, lit. Extra Dungeon), also known as secret dungeon or optional dungeon, is an optional location that is usually much more difficult than the main game with enemies that are much higher level than in other parts of the game. These dungeons are considered sidequests and often contain the most powerful equipment and, sometimes, summons that can only be obtained by completing the dungeon. The boss fought at the end of a bonus dungeon is often a superboss.
A game can have multiple bonus dungeons. Bonus dungeons are common features added to remakes of older games, to give experienced players new material to test their skills against, and to make the remake a more enticing purchase for players who have already completed an earlier version of the game.

Appearances[edit | edit source]
Soul of Chaos[edit | edit source]
Soul of Chaos is the collective name of the four bonus dungeons originating in the Dawn of Souls version. The bonus dungeons return in the 20th Anniversary Edition and iOS versions. The Android version does not have any bonus dungeons.
Each dungeon is tied to one of the four worldly elements and are initially sealed by a statue of their element's respective Chaos Fiend. Each dungeon, with the exception of Earthgift Shrine, is significantly longer than any in the main game. Major bosses from later games in the series are fought in the shrines, and the dungeons include many new and powerful pieces of equipment, as well as enemies that were not in the original game.
Labyrinth of Time[edit | edit source]
The Labyrinth of Time is the new bonus dungeon in the Final Fantasy 20th Anniversary and iOS versions. It consists of various floors, each containing a puzzle that must be solved on time to proceed. If the player fails to solve the puzzle in time, a dense fog will invade the area, sapping the party's HP and increasing the encounter rate, and the player will unlock the red seal of the floor when completing the puzzle, which is a sign of failure. Solving the puzzle in time unlocks its blue seal; either way, a passage to the next floor becomes available. Stages become available in a semi-random fashion on each playthrough. At the deepest floor, the player will face Chronodia, Master of Time. Chronodia is a new superboss whose appearance and strength vary depending on how many red and blue seals were unlocked within the labyrinth.
Soul of Rebirth[edit | edit source]
The Soul of Rebirth is a bonus quest in the Dawn of Souls, 20th Anniversary, iOS and Android versions. It becomes available after completing the game, after which the player can select "Soul of Rebirth" from the menu. Soul of Rebirth gives the player a party consisting of three party members they had in the past, with the addition of Scott. Except for Scott, the members join with whatever spells, equipment and stats they had when they left the party. Each of the characters' ultimate weapons can be found in the dungeon, and at the end of the quest, the player faces the light half of the Emperor.
Arcane Labyrinth[edit | edit source]
The Arcane Labyrinth is a set of dungeons in the 20th Anniversary, iOS and Android versions. It consists of a group of three dungeons, each with a set of player-generated floors and a static floor at the end containing only a boss. While they act collectively as a bonus dungeon, the Labyrinths can be entered and completed at any time. When all three are completed, the player gains access to a fourth area called the Arcane Sanctuary, where they may fight bosses and obtain rewards in return. Upon completion, the Sanctuary will be reset, and to re-enter and get a new reward, the player must complete all three Labyrinths again.
Sunken Cave[edit | edit source]
The Sunken Cave is located underwater, beneath the small island to the extreme southeast of the Surface World. The party will need to dive with the Nautilus to reach it. The Sunken Cave has a wealth of chests containing lots of equipment and a few items.
Saronia Catacombs[edit | edit source]
This optional area is accessible underwater in the southeast part of Saronia. The party can fight Odin here to obtain the Summon spell Catastro, and steal the Gungnir from him, as well pick up some equipment and items from chests.
Lake Dohr[edit | edit source]
Lake Dohr is to the west of Castle Argus over a small mountain range, requiring the Invincible to reach. The party can fight Leviathan here to obtain the summon spell Leviath. The treasure chests here contain a wealth of attack items, as well as some equipment.
Bahamut's Lair[edit | edit source]
The cave itself is located to the southeast of Vikings' Cove, but the player must cross the mountains to the east of Bahamut's Lair on the Invincible to reach the entrance. The party can fight Bahamut here to obtain him as a summon.
Eureka[edit | edit source]
Eureka contains some of the best equipment. A gateway to it can be found at the bottom floor of the Crystal Tower, but the Eureka Key is required. Doga and Unei unlock the Eureka Key, and give it to the Warriors of Light, granting them access to Eureka, knowing they need better equipment to fight Xande.
Iron Giant's Cave[edit | edit source]
??? is an unnamed, secret underwater dungeon present in the 3D remakes. It is named "Iron Giant's Cave" in the 20th Anniversary Ultimanias. To unlock the dungeon, the player must finish the Mognet sidequest and retrieve every letter. Located in the cave are Red Dragon, Green Dragon and Yellow Dragon, which have onion equipment as their common and rare drops, and a secret superboss, the Iron Giant.
Lair of the Father[edit | edit source]
Lair of the Father is an optional dungeon in all versions, where the player can acquire the Eidolon Bahamut. The player can visit the cave as soon as they have the Lunar Whale and fly to the Red Moon.
Cave of Trials[edit | edit source]
The Cave of Trials is a bonus dungeon appearing in the Advance and Complete Collection releases. It has eight floors and the final floor contains five weapons guarded by bosses, one for each of the five party members the player can swap out. The weapon can only be acquired if the correct member to wield it is in the party. Each weapon corresponds to one of the characters who become available after the Giant of Babil, so as to put them on-par with the rest of the group, who can acquire their ultimate weapons in the Lunar Subterrane. However, still stronger weapons can be acquired in the Lunar Ruins.
Lunar Ruins[edit | edit source]
Lunar Ruins is a bonus dungeon in Final Fantasy IV Advance and Complete Collection, unlocked by completing the game. It has ten sets of randomized floors, although the order of the sets is fixed. Each set, except the last one, has three normal floors and a fourth gateway floor, which contains a save point, a warp back to the surface that allows the player to exit the dungeon, a door that leads to each playable character's trial, and a stairway that leads to the next set of floors. The first three floors of each set are randomly selected from a pool of four or five pre-set floors. The first set also includes an additional entrance floor at the start, where the player gets a tutorial on their first exploration of the dungeon. The tenth and last set does not include a gateway floor, but after going through the first three floors, the player will arrive at the lowest floor of the dungeon (which also contains a save point and a warp back to the surface), where the superboss Zeromus EG awaits them.
The mobile phone version has an all new "EX Dungeon", which is a remake of the Lunar Ruins.
Challenge Dungeon[edit | edit source]
Every character with their own tale has a Challenge Dungeon. They become available to explore by talking to Challengingway after the tale has been cleared. The Challenge Dungeons are difficult multi-floor dungeons with powerful enemies and often bosses, but for completing them the player receives a rare item or equipment piece. Challenge Dungeons must be completed multiple times to win all the items they offer.
These dungeons are not available in the 3D versions.
Gil Cave[edit | edit source]
Gil Cave is accessed in the second world, connecting the Kingdom of Bal to the mainland entrance of the Big Bridge. By following a hidden path in the south of the cave, one can find the Gil Turtle Path. It houses a great treasure of gil, as well as dangerous and extremely powerful Gil Turtles, which are usually encountered every third step. The path may be completed multiple times for more gil.
Phoenix Tower[edit | edit source]
The Phoenix Tower is a thirty-floor tower in the merged world. Most floors possess two hidden staircases that are revealed upon examining the wall: both lead to the next floor, but one is unguarded, while the other is guarded by a random monster. Every five floors except the thirtieth has pots on the left and right sides of the room: one contains an amount of GP equal to the floor number multiplied by 1000, while the other is revealed to be a Magic Pot.
All encounters apart from the Magic Pots are inescapable, and the enemies tend to hit the party with strong status ailments. Completing the tower awards the Phoenix summon.
Sealed Temple[edit | edit source]
The Sealed Temple is a secret dungeon in the Advance and later versions. It is located underwater, south of Phantom Village, and houses four crystal shards with the jobs of Cannoneer, Gladiator, Oracle, and Necromancer, although the latter is not received until after the dungeon's main boss, Enuo, is beaten. In the temple, the player can find the strongest enemies and bosses of the game, including Omega Mk.II and Neo Shinryu. The Cloister of the Dead is unlocked by defeating Enuo.
In the World of Ruin, visiting any area other than Kefka's Tower after obtaining the Falcon is optional, but doing so allows the player to recruit former as well as new party members. Many players regard the recruiting of all the playable cast before the final battle as canon, and therefore, most areas in the World of Ruin are usually not considered sidequests or bonus dungeons.
Ancient Castle[edit | edit source]
The Ancient Castle is a ruined castle buried between Kohlingen and South Figaro. It is accessible once the Falcon has been obtained. While traveling beneath the sands, the man responsible for Figaro Castle's dive engine will mention they stumbled upon something; the player should decline further movement and go to the prison cells where the cell on the far right will provide the entrance to the Cavern to the Ancient Castle. Many enemies in the area have Reflect status and high Magic Defense.
Inside the Ancient Castle, the player will find the Odin magicite, which can be upgraded to the Raiden magicite in another area of the dungeon. The Blue Dragon, one of the eight legendary dragons, is found in a secret chamber of the castle.
Cultists' Tower[edit | edit source]
The Cultists' Tower was built by the Cult of Kefka, a group that worships Kefka Palazzo. The tower is the tallest structure in the game with dozens of floors over four screens of staircases. All offensive commands, except Magic, are sealed, and unless Umaro is brought along, the party is limited to the use of spells and items in battle. At the top lies the unique relic Soul of Thamasa, but taking it causes the leader of the cult, the Magic Master, to attack the party.
Dreamscape[edit | edit source]
The Dreamscape is a dream world formed from the mind of Cyan Garamonde, and is a reflection of the pain and hardships he has been through. It is accessible when the party rests in Doma Castle with Cyan in the World of Ruin. The Dreamscape is composed of four areas: a void of space with floating walkways connected by doorways; a recreation of the Phantom Train, but with new puzzles involving switches and treasure chests; a mine shaft, seemingly unrelated to a past location in the game; and an exact recreation of Doma Castle, though the party cannot exit the main gate.
Ebot's Rock[edit | edit source]
Ebot's Rock is located north of the town of Thamasa in the World of Ruin. Hidon, the beast Strago and Gungho hunted in their youth, lives there. The cave is dark, and the player only has a small circular area of sight. The player must collect enough Coral from chests to make a talking treasure chest move, allowing access to Hidon's chamber. The player can learn Strago's most powerful Lore from it.
Dragons' Den[edit | edit source]
The Dragons' Den is a bonus dungeon in the Advance and subsequent ports, located north of the Dragon's Neck Coliseum on an island with a single tree. Access is given once the player has defeated the eight legendary dragons. The player can obtain the most powerful equipment pieces in the den, guarded by the most powerful bosses.
Soul Shrine[edit | edit source]
The Soul Shrine is a bonus dungeon in the Advance and subsequent ports located on a small island near Mobliz. The shrine becomes available after the Dragons' Den and the main story have been completed. The Soul Shrine contains a series of 128 battles against most of the enemies and bosses, including the new dragons from the Dragons' Den.
Gongaga[edit | edit source]
Gongaga is an optional location which can be visited at any point in the game, and visiting it before Meteor is summoned allows the player to fight a brief boss battle and have access to some unique dialogue. The area is composed of a village as well as three interconnected sub-areas featuring random encounters: a jungle, the Reactor Wasteland, and the Meltdown Reactor. Both the Deathblow and Titan Materia can be found in Gongaga.
Shinra Mansion[edit | edit source]
The Shinra Mansion is a building located in Nibelheim with story importance. It is first visited in a flashback after the party has arrived in Kalm, during which the player will not run into any random encounters. It can later be revisited as an optional dungeon after the party has reached Nibelheim, with random encounters and a puzzle which, once solved, allows the player to recruit Vincent.
Da-chao Statue[edit | edit source]
The Da-chao Statue is the monolithic sculpture sculpted into the mountain overlooking Wutai Village. It is part of Yuffie's sidequest. Although the entire area is optional, this is the only part of it that is dungeon-like and features random encounters.
Ancient Forest[edit | edit source]
The Ancient Forest is located in the Cosmo Area and is accessed with a green, black or gold chocobo, or by defeating Ultimate Weapon. In the forest, the player must solve some puzzles to find rare Materia and weapons.
Gelnika[edit | edit source]
The sunken Gelnika is a crashed airplane that lies on the Bottom of the Sea to the south of Costa del Sol. The plane can be accessed with the submarine. Even after sinking to the ocean floor, the plane's interior keeps from flooding, allowing for one to enter the sunken aircraft from the ocean. Gelnika holds some of the most difficult random encounters, and also some of its best treasures.
Tomb of the Unknown King[edit | edit source]
The Tomb of the Unknown King is a location near Deling City, and by doing the sidequest inside the player can obtain the Guardian Force Brothers. Most of the areas are tunnels, making the tomb appear straightforward, but if the player backtracks, the viewpoint will change, potentially confusing the player. The player will drop a SeeD rank if they venture out of the tomb before the objective is fulfilled.
Centra Ruins[edit | edit source]
The Centra Ruins is on the Centra continent. Upon entering the ruins, a timer begins and the party must find a series of red gemstones and place them in the eyes of statues to acquire the secret code to access the room where Odin is fought. The Tonberry King also appears randomly once 20 or more Tonberries have been killed. Defeating him earns the player Tonberry as a Guardian Force.
Deep Sea Research Center[edit | edit source]
The Deep Sea Research Center is a hidden island far out in the middle of the ocean, in the very southwest corner of the world map. It is an abandoned, half-sunken laboratory formerly used to research draw effects. In the first area the player must face Bahamut, and after defeating him and earning him as a Guardian Force, the player can advance deeper into the ruins after leaving, talking to a person, and returning.
Cavern of the Stolen Fayth[edit | edit source]
The Cavern of the Stolen Fayth is located in a gorge to the north of the Calm Lands, near the entrance to Mt. Gagazet. The cave hides a fayth that legend says was stolen long ago to prevent summoners from completing their pilgrimage. At the end of the cavern, the player fights a boss, and gets the chance to recruit Yojimbo as an aeon for Yuna. In the International and HD Remaster versions, the party can fight Dark Yojimbo after obtaining the aeon, leaving and reentering the dungeon.
Omega Ruins[edit | edit source]
The Omega Ruins is a large dungeon located within a small group of islands to the east of Spira's main continent. Unlike many of the other locations, the cave must be mapped by the player. At the end of the cave, two deadly bosses await the party: Ultima and Omega Weapons.
Because of the game's non-linear nature, many areas and missions are optional. Completing most of the areas is still needed for 100% story completion, although some areas are truly optional, and do not affect story completion.
Ruins Depths[edit | edit source]
The Ruin Depths is an optional dungeon in the Calm Lands, situated behind and on a lower level than the Calm Lands Ruins. It does not have a mini-map, and contains some rare and unique treasures. The dungeon is unlocked by a complicated process of chocobo raising and exploration.
The boss of the area is the Anything Eater. Once it is defeated, all five sets of locked doors open. The final door gives access to the Amazing Chocobo. A Garment Grid with the constant ability of Break HP Limit is the prize for getting to the Amazing Chocobo. The Ruins are not part of 100% completion or the main quest.
Fiend Colony[edit | edit source]
The Fiend Colony is an optional dungeon located on the Mi'ihen Highroad. The player must dispatch a level four or five chocobo to the highroad from Clasko's Chocobo Ranch during Chapter 5 to access it. To travel through the dungeon, the player must destroy stone walls with bombs. Once the player reaches the back of the cave, they will fight the King VERMIN!. Defeating him nets a new Garment Grid. Completing Fiend Colony is not needed for 100% story completion.
Den of Woe[edit | edit source]
Den of Woe is a hidden cave in the Mushroom Rock Ravine accessed by placing all ten Crimson Spheres on the door. Many of the spheres have special requirements to be obtained and are well hidden. The Den of Woe contains no treasure, but has some boss battles. Although Den of Woe is a sidequest, unlocking and entering the Den is necessary for 100% completion.
Via Infinito[edit | edit source]
Via Infinito is a 100-floor dungeon beneath Bevelle. In the final cloister the party can challenge the superboss, Trema. Each cloister block of 20 floors has about 6 level designs that appear at random. The dungeon swarms with monsters, and equipping a Charm Bangle for No Encounters will have no effect. Every oversoulable fiend, except for the Georapella and Precepts Guard, can be found here. Valuable accessories and Crimson Spheres can be obtained from the defeated bosses. Completing Via Infinito adds to story completion.
Necrohol of Nabudis[edit | edit source]
The Necrohol of Nabudis was once the capital of the Kingdom of Nabradia, but its remains have become corrupted by the thick Mist that covers the region. The location is not part of the main storyline, and in the original version houses the game's ultimate weapon, the Zodiac Spear. The player can access the area as soon as the Dawn Shard has been acquired, which means that the game's ultimate weapon can be acquired fairly early. The Esper Chaos resides in the Necrohol, as do some marks and rare game. However, the party cannot obtain Chaos until they have at least reached Archades, as one of the items needed to reach him requires a miniquest to be completed there.
Great Crystal[edit | edit source]
Even though Great Crystal is visited as part of the storyline, only a small part of it is mandatory. If the player returns after having obtained the Treaty-Blade, they can travel into the deepest parts of the crystal. The area has no in-game map, and the interior is like a maze with many dead ends and paths that need to be unlocked. The Esper Ultima and the superboss Omega Mark XII reside within the crystal, as well as several rare game.
Henne Mines[edit | edit source]
Henne Mines is a mandatory story location, but its true depths can only be explored after obtaining ten Espers and asking the geomancer in Jahara to open the locked gate within the mines. At the mines the player will encounter some of the toughest regular monsters in the game, and at the end of the mines, battles the ultimate Esper, Zodiark.
Midlight's Deep[edit | edit source]
Midlight's Deep is a secret dungeon in the US and PAL versions that features the hardest challenges and is located in the Keep of Forgotten Time. It consists of ten levels and the dungeon can be exited at any time, though the party must start back at the first level when reentering. On the tenth and final floor resides the superboss Yiazmat.
Faultwarrens[edit | edit source]
The Faultwarrens is an optional location on Gran Pulse. It is where the fal'Cie Titan resides breeding increasingly powerful monsters and pitting them against the party. Some of the tougher missions are fought here, for a variety of prizes.
The Ultimate Lair is located in the Dead Dunes and can be accessed on the "extra day" via a new Cactuar statue that appears outside the Ruins East Gate. The Lair is full of Last Ones, and is imperative to visit to complete a certain side quest, as it is the only location during a regular playthrough where Meonekton Ω will spawn due to having to kill a prohibitively high number (65,535) of the regular monster otherwise. If Lightning already drove a particular species into extinction, those specimens do not appear.
Within the Ultimate Lair, the game clock does not stop, even during battle, and Chronostasis is disabled. Lightning must keep moving to reach the deepest level. After defeating the enemies on each level she gains access to warp devices that lead to lower floors. On the last floor she can battle the game's superboss, Ereshkigal.
Most duties are not part of the main storyline and are unlocked via sidequests. Thus far all raids and Hard modes of dungeons are not mandatory, including those based on dungeons that were part of the main storyline.
List of bonus duties:
Pitioss Ruins[edit | edit source]
Unlike other dungeons, Pitioss features no enemies. Instead, Noctis must enter this dungeon alone and complete a series of complex puzzles. For completing the challenging dungeon, the player is rewarded with the Black Hood, though various good items and equipment can be found within.
Sealed dungeons[edit | edit source]
Eight of the dungeons found have sealed doors within their depths that hide a secondary dungeon that feature significantly stronger monsters. The sealed doors can be opened after completing the main game and the basic form of the dungeons containing these doors. The player must visit Meldacio Hunter HQ and speak to Ezma Auburnbrie who will present Noctis and his friends with the key to open the sealed dungeon doors.
- Keycatrich Trench
- Balouve Mines
- Greyshire Glacial Grotto
- Fociaugh Hollow
- Steyliff Grove
- Daurell Caverns
- Costlemark Tower
- Crestholm Channels
When the party first comes across a locked door to one of the bonus dungeons, Prompto Argentum remarks that he wishes they had a key that can unlock any door "just like in video games". The Windows and Royal Editions add monoliths to the menace dungeons that extol the stories of rulers of yore seeking to protect their realm from these "menaces".
Midlight's Deep[edit | edit source]
Midlight's Deep is located on an island east of the Port City of Warjilis. It consists of ten levels and is home to the most difficult enemies and the best treasure through the Treasure Hunter ability. Only the first level is initially accessible. To get deeper, the player must fight a random battle, but simply defeating every enemy will not work, instead, the player must find a passageway to the next level that is hidden in one of five different squares on each floor. To find the exit, a unit needs to step on that square. The tenth level holds a regular storyline battle with the secret Lucavi demon Elidibus, who uses the Zodiac summon, which can only be learned from him.
Some of the strongest enemies reside in Brightmoon Tor. At the top of each Brightmoon Tor is a watch that have enemies at level 90 and above. Although the items the dungeons contain may only be obtained once, multiple attempts can be made to retrieve them. If one failed to notice them the first time, or simply did not have the required equipment, one can try again.
Tower of Agito can be entered via the airship, Setzer, and boasts a hefty challenge. The player must complete five series of battles and defeat 100 of a specific enemy, all of whom are at level 128. The player may access relic terminals prior to entering each challenge, as they cannot leave until all 100 enemies are defeated. Rare accessories are available, with the final prize at the top being the best accessory, the Agito Insignia.
The Nasty Dungeon features monsters in large variety of groups, and the dungeon has branching pathways with no indication as to which path is the correct one. Enemy groups can easily reach up to fifteen monsters per battle, and surprise attacks can become a constant threat. However, the treasure found inside is well worth the player's effort. The Nasty Dungeon is not strictly optional: the player must enter it to collect the Pegasus just past the entrance. A fairy posted by the chest will warn the player about the danger, advising them to take the MAGI and leave.
There many optional dungeons to explore found in various areas. Some of them become inaccessible after a certain point. The dungeons are simple to navigate and contains valuable treasures.
Holy Tree Tower, Moonsand Ruins, Mysterious Lighthouse and Trial Tower become available after the player obtains the Master Key. Each tower is 100 floors tall with special floors every 10 floors where the player can leave the tower to save. Sometimes the special floors have bosses or a merchant or a treasure chest. Some of the best equipment can only be obtained as random treasures in the bonus dungeons.
The EX Dungeons become available after clearing every Intervention quest, then defeating the final boss. Three Gates will appear inside The Girl's Tearoom with the fourth appearing after the others are cleared. Reaching the final area of dungeon Z is the superboss, XG.
In the Maxima version, clearing EX Dungeon Z unlocks another bonus dungeon, the Hidden Dungeon. A purple gate will appear on the seventh floor of the Crystal Tower. Each route will have one of the Four Fiends at the end of them: Earth with Lich, Fire with Marilith, Water with Kraken, and Wind with Tiamat. On the final route, the twins will battle all four with the superboss, Garland.
