Tanren Chambers, also called TC or the 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 different chambers that include all 17 types from Normal to Ghost. They all go up to floor 99, but they have many alternate endings on lower floors, with a variety of prizes.

The Pokémon in this dungeon are mainly in the level range of 40-50.

For a complete guide about how to beat Tanren Chambers, please see Foxie's guide on the PMU Forums.

Chambers Master List


Some features are explained on the main page. You can click exit and switch icons to move to related sections.

1F rewards

  • Item 1
  • Item 2
  • Item 3

This section is an example. Each chamber page has a list of features specific to Tanren Chambers. 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 Key, the floor has an item called Key Tanren Key spawned somewhere on the ground. Those are essential for advancing through the Empty-type Switch points. If the Key Key is marked with H, that means the key is buried in the ground on that floor.

If the floor has an TreasureChestY Exit, then that means the regular stairs lead to it instead of the next floor. If you use the exit, you'll be presented with a TreasureChestY Deluxe Box that contains one of the specified items in its rewards table, with the exception of Normal 99F, which presents you a Mystery Part as well as a Grand Box. You have to use Empty-type 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 TreasureChestY Exit icon in the table to jump to the respective rewards table.

If the floor has 151MS Mew, then Mew spawns (initially invisible) on the floor. Said invisibility comes from Invisible status and has all its weaknesses.

If the floor has a Empty-type 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, relative to the chamber on the map to the right. To unlock the stairs, you have to use a Key Tanren Key. You can click on a Empty-type 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.

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

  • Before Tanren Chamber's release, Sprinko released this clue on his DeviantArt page. People correctly guessed it was a map, and each circle represented a different Pokémon type.
  • 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.
