Arcane Labyrinth The Arcane Labyrinth is a set of dungeon s featured in " Final Fantasy II Anniversary Edition " . It consists of a group of three dungeons , each with a set of player - generated floors ( see below ) and a static floor at the end containing only a boss . While they act collectively as a bonus dungeon , the Labyrinths can be entered at any time and completed , and due to their mechanics must be traversed several times throughout the game to get the most out of the rewards . Story . The origins of the three Labyrinths are unknown , but long ago they were used to seal away Destroy , the ultimate magic . The Guardian of the Destroy Tome , Deumion , awaits in High Altar of the Arcane Sanctuary where the Destroy Tome is kept . Various floors in the Labyrinths contain travelers who hint they entered the Labyrinths to try and find a way to reach Deumion and discover the power he guards , but their attempts failed . The Labyrinths alter space and time to create their floors , in the cases of the four key words related to Deumion directly recreating events that occurred in the ancient past , and bringing characters and monsters from throughout the game together in their floors . Labyrinth Locations . There are three Arcane Labyrinths : The North West Quarter is located far west of Salamand , the North East Quarter is north of Bafsk , and the Southern Quarter is west of Kashuan . The Arcane Sanctuary , the fourth area , is located shortly north of Poft . Traversing . When the player enters any of the three Labyrinths , two Black Mages will offer them advice . One hints about combinations of words that create beneficial effects , and the other , if told a Key Term , will tell how much good fortune he senses in the word for each of the current party members . In all three Labyrinths , the player cannot Warp or Teleport out , and cannot save . When the player approaches the flame and tells it a Key Term , a portal appears that warps the player to the next floor , whose appearance is pre - set depending on the Key Term used . All floors have some sort of challenge to perform , and as a reward the player will receive a new Key Term , or a hint for the challenge of another floor . All floors contain another flame where they can use another Key Term to create the next floor , or can warp out of the dungeon . A Key Term can only be used once per Labyrinth . The North West Quarter has four floors , the North East Quarter has seven , and the South Quarter has ten . After traversing all floors , the player arrives as a final floor where a final flame manifests a boss enemy for them to fight , the difficulty varying depending on the Key Terms used . As the player completes each Labyrinth , a flame lights on a torch in the Arcane Sanctuary corresponding to the relative position of the completed Labyrinth to the Sanctuary on the world map . With all three Labyrinths completed , all three flames light and the door down to the High Altar is unsealed . At the High Altar Deumion will manifest Phrekyos to fight the party , and when it is defeated he will ask them what they seek . The player must tell Deumion a Key Term , which in combination with the Key Terms used in the three Labyrinths , will prompt a reward from him . The reward will either be an Elixir , a character ' s exclusive ultimate weapon , or one of two new spells . At the end of the game , the Key Term Jade Passage unlocks Oblivion , the first in a sequence of four Key Terms ; Oblivion , Hope , Destruction , and Guardian , which tell the backstory of Deumion . When Deumion is next reached , telling him Destruction will prompt a battle with Deumion himself , with the unique Destroy Tome as the reward . If they instead give him the Light of Hope , received on the Guardian floor , he will give them the Revive Tome . Once one of the two tomes is received , the player can never receive the other . After receiving their reward from Deumion , the Sanctuary will be reset once the player leaves . To re - enter and get a new reward , the player must complete all three Labyrinths again . Key Terms and floors . There are 45 possible floors in the Arcane Labyrinth , but no more than 21 can be chosen in each run . On floors with a challenge to do , the challenge is almost always optional , and the player can choose to skip to the portal to the next floor and avoid the challenge , beneficial if they already have received the reward . With the exception of the four Key Terms directly related to Deumion , Key Terms are divided into four categories which relate to each other . When the player uses a Key Term to create the next floor , depending on the Key Term used to create the current floor , the quality of treasure and enemy encounter rate will change . The properties of a new floor depend on the keyword of the current floor , i . e . if you are at a " Locations " floor and choose a keyword of the " Magic and Spirits " class , the next floor will have bad treasure and high encounter rates . Uncategorized floors will not affect the string of keyword classes , keeping the previous class . In addition , there are five combinations of keywords that offer a floor with good treasure and no random encounters whatsoever . These are very handy , since in each case there is one keyword that offers a difficult floor . The combinations are : Floors . The following is a list of the Arcane Labyrinth ' s possible floors ordered by the class the keywords belong to .
