Like other Marowak Dojo mazes, the player is not allowed to bring any items. Items have to be deposited into Kangaskhan Storage before entering, or they will be lost forever. Unlike the other mazes of the dojo, the player will lose some items should they faint; additionally, Pokémon can be recruited here. The player cannot be rescued if knocked out here; for purposes of Treasure Boxes, all floors are ranked E.
There's 1-4 items on each floor and 3-5 starting enemies. Unlike other postgame dungeons, there are no traps to be found here - the game will simply spawn 2 to 4 Wonder Tiles. This dungeon contains all 88 TMs present in Explorers of Time, Darkness and Sky, including the otherwise rarely seen Dream Eater TM. In Explorers of Time and Darkness, this is also the only place where the player can find HMs.
Floors 1 through 29 are medium-sized with 3-9 rooms, while floors 30 through 48 are large-sized with 3-12 rooms.
There is light darkness in this dungeon. There is water on floors 21 through 24, 26 through 39 and 41 through 43, as well as floors 46 and 48. There is lava present on floor 40.
In Explorers of Time and Darkness, after the Marine Resort's location is revealed, the player will encounter Jirachi, Suicune, and Moltres at B23F, B29F, and B40F respectively. In Explorers of Sky, all three of them have been removed from the dungeon and placed in different locations.
After clearing the maze, Marowak will give the player a Brown Bow as a holdable item, which supposedly once belonged to his grandfather.
Pokémon encountered
Each time player enters a floor, only 14 of the following species that can be found on a given floor will be chosen. The unpicked Pokémon's spawn rate will be added to whichever picked Pokémon is next in the National Dex order, going back to the beginning if needed.
All of the Pokémon encountered in the Final Maze appear in the Dojo's various mazes (with the obvious exception of the aforementioned Legendary Pokémon). Therefore, the Final Maze could be considered a "spawning ground" of sorts.
The BGM was changed from Time and Darkness to Sky, along with the other changes.
Although the dungeon's Legendary Pokémon were moved to new locations in Pokémon Mystery Dungeon: Explorers of Sky, the associated tilesets for their floors were kept for unknown reasons.
