Lunar Ruins

Lunar Ruins is a bonus dungeon in Final Fantasy IV Advance and Final Fantasy IV: The Complete Collection. It is located at the Stone Face on the Red Moon, an allusion to the "face" found on Mars in the real world. It is unlocked by defeating Zeromus.
The mobile phone version has an all-new "EX Dungeon", which is a remake of the Lunar Ruins.
The Stone Face is the new location of Golbez's second Challenge Dungeon in Final Fantasy IV: The After Years.
== Layout ==
thumb|right|The Lunar Ruins' hall.
The Lunar Ruins' floors are randomized, and the player will rarely experience the same pattern of floors twice. However, there are a few particular patterns.
There are ten sets of randomized floors, although the order of the sets themselves is fixed. In each set except the last one, there are 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 among 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 instead, 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.
In the normal floors, the player just needs to reach the exit. In many of them, there are enemies to battle and treasures to find.
Among the randomly-selected floors, there are two villages which may appear that sell rare items and equipment at prices upwards of 100,000 gil. By this time, the player should be able to afford them, as enemies are likely leaving over 20,000 gil a battle.
Shrines with Sylphs may also occasionally appear. There are two of them; one contains only one Sylph, who will restore the party’s HP and MP, whereas the other contains three Sylphs who, in addition to the full restoration, will grant the player a Megalixir.
There are floors where old men quiz the player. If answered correctly, the player will receive a prize and/or unlock the exit.
In challenge floors, the player must win a challenge to proceed. In one, the player must memorize a code and find and hit the buttons in the right order; in another, they are requested by a boy to find and kill a "Platinum Toad".
"Floors of Remembrance" mirror the floors of previous dungeons the player has visited, and they can encounter enemies from that dungeon in addition to new enemies. All of the chests that existed in the original dungeon are present, but the items they contain are different. Some of these floors also have added chests that were not in the original dungeon.
There is a floor that consists entirely of Flan monsters resistant to physical attacks, and another of monsters resistant to magic. NPCs will appear when the player enters these floors to tell them about this.
There are floors where mini-bosses or special enemies appear on the map, and the party must navigate through them to proceed.
There is a floor full of living dolls that initiate a battle if they come in contact with the player. Defeating all dolls will cause a chest containing Nirvana, Porom's ultimate weapon, to appear.
Finally, near the bottom of the shrine, the player may find a floor containing the Brachioraidos, the hardest boss. A man at the floor entrance warns the player not to face it. It drops the strongest shield, the Hero's Shield, which cannot be acquired anywhere else.
== Floors ==
This list of floors does not reflect any actual order, most of the floors being randomized.

== Trials ==
The only floors which the player is guaranteed to find are the trials. The trials are unlocked for each character once they defeat Zeromus, testing the player in multiple ways, and ending with battles against Lunar versions of the summons. After defeating one of the Lunar Summons, the player gains a Grimoire for that summon, and is able to summon the Lunar Summon in battle once.
After completing a trial, the player gets either an ultimate weapon or a piece of armor for the character whose trial has been completed. To re-do a trial, the player must use the Grimoire, gained from defeating the Lunar Summon in that particular trial, in a battle, exit the dungeon and re-enter it.
=== Yang's Trial ===
Yang's trial is one of strength; the party must defeat many monks working in teams of eight—Monk Warriors, Super Monks, and Master Instructor. After defeating all the monks the party fights Lunar Titan. After its defeat, Yang gets the Martial Armlet, which turns his Focus command into Deadly, which charges and then triples the damage.
=== Edward's Trial ===
thumb|right|Edward's Trial.
Edward winds up in an illusion of Damcyan Castle's ruins, covered in ice and snow. The party is attacked by a Specter. It cannot be killed through normal means, but Edward uses the Requiem Harp to Sing and, in addition to the usual effect, he plays a Requiem, thus giving the tortured soul eternal rest. All the Specters (blue flames) throughout the ruins must be killed and Edward must use Sing while the Requiem Harp is in the player's inventory to lay it to rest. The spirit must be killed once before Edward will use Requiem. The party eventually finds an underground waterway and reaches a room where a fight with Lunar Shiva ensues. After her defeat, Edward gets the Harmony Ring, which changes his Sing ability into Chant, casting Protect and Shell on the party.
=== Rydia's Trial ===
thumb|left|Rydia's Trial.
Rydia enters a cave filled with mist. She turns back into a child, and Ifrit, Titan, Ramuh, and Shiva abandon her. The party must find them and defeat them to regain them. After defeating them the mist dissipates, and the party fights Lunar Mist Dragon. After defeating it, the player gets the Mist Ring, which improves Rydia's Mist Dragon summon and grants the party the Blink status. If you have a summon on the very bottom right corner of Rydia's Summon spell list. It will disappear when she becomes a child.
=== Cecil's Trial ===
thumb|right|Cecil's Trial.
Cecil enters a castle and is addressed by an unknown voice, who tests his abilities to do good deeds as a paladin. Cecil progresses through several rooms where he must prove himself as a true paladin by doing good deeds, such as by not taking treasures from others, fulfilling requests properly, helping other people and so forth. Cecil meets the king of the castle who gives him a sword based on the trial's success. If he does everything right, Cecil gets his ultimate weapon, the Lightbringer. If he fails even one test, he gets a weaker weapon, and gets a useless Throw item for Edge if he fails all of them. The player fights Lunar Odin regardless of which weapon they received.
=== Rosa's Trial ===
thumb|left|Rosa's Trial.
Rosa enters a town that is promptly destroyed. She must heal the injured townsfolk, fourteen in total, but must beware of other villagers who are just Metamorpha in disguise. After healing as many as possible before the time runs out, the party fights Lunar Asura. After her defeat, if Rosa healed all fourteen people, she gets the White Ring, which turns her Pray command into Miracle.
=== Edge's Trial ===
Edge winds up in a labyrinthine castle. He finds his way to the king and compliments the castle, but is dropped into another portion. He must find his way back to the king through a series of hidden passages, Pitfalls, traps, switches, and so forth. The Palace Guards drop Keys if defeated, needed for doors. After the ordeals, the player fights Lunar Ifrit. Edge gets the Hanzo Gloves, which turns his Steal command into Plunder, increasing the chances of a successful steal, as well attacking at the same time.
=== Kain's Trial ===
Kain enters the town of Baron where there have been several murders by a lance-wielding assailant. Kain investigates, and after Rosa is kidnapped, he is suspected as the culprit and is arrested. Kain clears his name, but does not feel content, and during the night, he sees Cecil walk into the Devil's Road house. Kain follows him and is warped to a strange mirror room where Rosa is bound and Cecil is unconscious on the floor.
In the mirror, he sees the dark reflection of himself, which is tempting him to kill Cecil. Kain can elect to do this, but the trial will end. Kain refuses, and must engage in simple combat with a Shadow version of himself, which transforms into Lunar Bahamut. After Kain defeats Lunar Bahamut, he gets Abel's Lance, his ultimate weapon, which sometimes casts Tornado when he attacks, even if the enemy is immune to it, as well as the Dragoon Gloves, which allow him to Double Jump and increase his power.
=== Cid's Trial ===
Cid appears on an island, near his airship. A person on the airship asks him to fly him to a destination before the timer reaches a certain limit. At the destination, another person arrives and wants to be flown to another destination in a lesser time limit. After a while, Lunar Ramuh is angered about Cid flying all over his skies and attacks. After his defeat, and if all of the passengers are delivered on time, Cid gets the Flare Sledgehammer, his ultimate weapon, which casts Flare at random when he attacks.
=== Palom and Porom's Trial ===
Both Palom and Porom must be in the party to perform this trial. Palom and Porom must work as a team, inflicting various status ailments on themselves to infiltrate a series of hidden passages. Switches in one passage typically open doors in the others, forcing them to work together and the player to switch control between the two frequently. Once they reach the end of the passages, the player fights Lunar Leviathan, and Palom and Porom get the Twin Stars accessories, which enable them to cast the stronger Double-Meteor spell when using the Twin command.
=== The Final Trial ===
thumb|right
After the characters' trials, the last floor of the ruins contains the superboss Zeromus EG. They can choose not to fight him and can simply warp out of the ruins. Fighting Zeromus EG earns no rewards except for his Bestiary entry.

==Behind the scenes==
The concept of trials relevant to specific characters and their abilities appears to be inspired from the Finale Chapter of Live A Live, a game made by Square and a majority of the Final Fantasy team at the time, three years after the release of the Super Famicom release of Final Fantasy IV, and most notably directed by Takashi Tokita, who also has an extensive profile in scenario design in the Final Fantasy series and in his career at Square. Edge's trial resembles the trial of the ninja Oboro-maru in the Live A Live series, the Dungeon of Keys. Both involve defeating enemies for keys, and navigating through a labyrinth. The game also served as an inspiration for Final Fantasy IV: The After Years.
Many concepts for the Lunar Ruins were reused for Final Fantasy IV: The After Years. Yang's Lunar Trial consists of him fighting past rows of monks, and his Challenge Dungeon is similarly a gauntlet of corridors with high-powered enemies. Rydia's Lunar Trial is to defeat Titan, Shiva, Ramuh and Ifrit before fighting the Lunar Dragon, while in The After Years the Mist Dragon returns to Rydia once Titan, Shiva, Ramuh, Ifrit, and Sylph are defeated. Porom's Challenge Dungeon has her travel around a field performing good deeds, including offering healing services, and must help as many people as she can within a time limit, similar to Rosa's Lunar Trial. Troia Castle is frozen over by Shiva in The After Years, similar to the recreation of Damcyan in Edward's trial, while Eblan is attacked by Ifrit much as Lunar Ifrit serves as the master of the castle in Edge's trial. Dark Kain reappears in The After Years as a major antagonist, and in a flashback manifests as he did in Kain's Lunar Trial, emerging from Kain's reflection in a mirrored chamber and attacking him. The idea of the Challenge Dungeons themselves—bonus dungeons reflective of the characters whose tale the player is playing—is also reminiscent of the Lunar Ruins.
