Secret Dungeons are hidden dungeons opened for an exact one hour, which can only be found in the five Halls of Elements (Halls of Water, Fire, Wind, Dark, Light) as a random stage clear reward. Secret dungeons consist of 10 stages, with each stage requiring players to defeat waves of one particular monster. Clearing a certain amount of stages awards players with summoning pieces for that monster. Once enough pieces have been acquired, players can summon that monster at the Summoning Circle. The number of pieces required depends on the grade of that monster. The element of the dungeon's monster depends on which Hall the Secret Dungeon was discovered in, with the Hall of Light giving only Light monsters, and so on.


Finding a Secret Dungeon

Only one Secret Dungeon may be discovered at a time, although players may enter into other players' dungeons if they have been befriended. A Secret Dungeon that's been discovered is available to all players in the friends list, whether that person was befriended before or after the discovery. Once 10 different friends have entered, it will be permanently inaccessible for any other friend that tries to enter. If a friend enters a player's Secret Dungeon, that player is awarded one extra monster summoning piece (only one piece per friend, regardless of how many times that friend runs the dungeon).


Each Secret Dungeon consists of 10 stages, with increasing monster levels at each wave. The awakened version of the monster will start to appear stage 3. On the final stage, a boss version and two awakened versions will appear.

Drop infoEdit

Upon clearing each stage, the number of summoning pieces that can be obtained will slowly increase. In addition to a base reward, there is also a chance of obtaining an additional summoning piece.

If you quit the battle at any point (through the pause menu) you are awarded as for the last cleared stage. This can be used as strategy to instantly end the run and maximize your time.

The following table shows the rewards for each stage as well as the chance for obtaining a bonus summoning piece.
