Tanren Chambers

Tanre Chambers is a dungeon that was made as a celebration for 150 players on PMU at any one moment. It has many different chambers that include all 17 types from normal to ghost. They all go up to floor 100, but it has many alternate endings on lower floors, with a variety of prizes.

Normal Chamber
The Normal Chamber is always the chamber the player goes to when they begin the dungeon. It holds 2 beginning keys at 2 and 4.

Fossils
Fossils are one of the few things that make Tanren Chambers really special.
