Tanren Chambers

Tanren Chambers, also called TC or chambers by players, is a dungeon that was made as a celebration for having 150 players on PMU at a single time. It has many "chambers" that include all types excluding Fairy. All chambers go up to Floor 99, but they have various alternate endings on lower floors, each with their own pool of items in a Deluxe Box.

For a complete guide on how to beat Tanren Chambers, see Foxie's guide on the PMU forums or its counterpart on this wiki.

Attributes
When players enter Tanren Chambers, they start in the Normal chamber. A "chamber" is recognized as a variation of Tanren Chambers you can switch to via locked stairs (or "switch points") found inside all chambers on specific floors. These locked stairs point in a direction, which correspond to the position of the chamber it leads to from the one you're in, seen on the map. For example, in the Normal chamber, if a switch point's red dot is pointing northeast, it will always take you to the Fighting chamber.

Every chamber in Tanren Chambers also contains keys known as Tanren Keys, and multiple regular exit stairs on specific floors. To get to specific exits, one has to work their way around the other exits by going into different chambers and back to the chamber with the desired exit. For example, going through Normal chamber from the beginning can only ever take you to its exit stairs on Floor 12. Tanren Chambers will not be counted as completed until any Floor 99 exit is taken. Tanren Chambers is often considered conquered through the Normal 99 exit, which is the only place to obtain a Mystery Part, and the Grand Box, which is Normal 99's unique box type.

Below is a master list of all the chambers you can access in Tanren Chambers.

Article Information
This section is an example. Each chamber article has a table of features specific to that chamber. If any specific cell is empty, it means the respective floor (row) doesn't have that specific point of interest.

If the floor has a key, that floor has a  Tanren Key spawned somewhere on the ground. Those are essential for advancing through the switch points. If the key is marked with H, that means the key is a hidden item on that floor.

If the floor has an exit, then that means the regular stairs lead to an exit instead of the next floor. If you use the exit, you'll be presented with a Deluxe Box that contains one of the specified items in its rewards table, with the exception of Normal 99, which presents you a Mystery Part as well as a Grand Box. You have to use switches to stay in the dungeon and go farther, which may not necessarily be on the floor with any specific exit. You can click on a exit icon in the table to jump to the respective rewards table.

If the floor has Mew, then Mew will spawn invisible on the floor. Mew can be already spawned on a floor, or can be spawned through Honey or a Summon Trap. When Mew spawns, music on the floor changes to PMDB) Final Island. Mew can be defeated and will sometimes drop a Life Ring, its family item.

If the floor has a switch point (up to 8 per floor), then there's locked switch stairs somewhere on the floor, marked with a red dot that points to the direction it goes. To unlock the stairs, you have to use a Tanren Key. You can click on a switch icon in the table to go to the respective chamber page or hover the pointer over it to display a tooltip with the destination chamber's name.

Trivia

 * Tanren Chambers was created by Sprinko.
 * Before Tanren Chambers' release, Sprinko released the map image as a clue on his DeviantArt page. People correctly guessed it was a map, and each circle represented a different Pokémon type.
 * Tanren Chambers was created before the Fairy-type existed, therefore no Fairy-type based chamber exists and its type-enhancing items reside in other dungeons.
 * The entrance formerly was fully lit, but later had darkness added to it.
 * As of July 2017, Tanren Chambers became the first and only dungeon where a Legendary's family item could be obtained by the addition of Life Ring for Mew.
