Secret Room

Secret Rooms are a feature that was added to the game in PMU7. They appear in Random Dungeons and are uncommon to be released. The dungeons are randomly set on a floor.

The secret rooms have boxes that can give rare items or common items when opened at the Grassroot Bazaar with the help of the Xatu Appraisal service.

Location
The location of the Secret Rooms are randomly generated on a floor and can appear in a number of dungeons. All the dungeons that the secret rooms appear are randomly generated.

The Secret Rooms are located between floors, for example if you enter a secret room on floor 25 when you exit the secret room you will appear on floor 26.

Pokemon
In certain secret rooms it is possible to spawn Pokemon with Honey. The pokemon that spawn in these rooms are often rare pokemon that can only be gotten here. The pokemon that spawn in these rooms are as follows;
