Secret Room

Secret Rooms are a feature that was added to the game in PMU 7. They appear in set floors throughout several dungeons and can be rarely found and accessed by stepping onto a hidden stairs tile. Secret Rooms only appear in randomly-generated dungeons. Fixed dungeons such as Friendship Forest will never have Secret Rooms.

Secret Rooms often rewards players with a varying amount of Deluxe Boxes that can give items when opened at Xatu's Appraisal. However, Secret Rooms may also allow players to spawn rare, exclusive Pokémon with Honey.

When you summon the Pokémon via Fossil, the Pokémon will be at Level 25 recruitment rate of 100%.
