Secret Chamber
Central Seafloor Ruins has a unique Secret Room; the Secret Chamber, or well known as the "Phione Secret Room". It is found on Floors 51 to Floor 59. This Secret Room contains no Deluxe Boxes but instead a platform where one can summon Phione. Upon entering there is a locked door. The player needs to use Sea Dew to enter the summoning area, and then Wonder Egg on the pedestal inside said area to summon Phione. The Phione has a 100% recruit rate and has a boss buff of 1000 hp. Note that it and the other Secret Room spawn on the same floors, so if Secret Room stairs are found, which one entered is random.

Dungeon Objective

Once the player has a Wonder Egg found in the final Deluxe Box they then need to re-enter the dungeon and find the Secret Room on Floor 51+. A Sealed Chamber can be found in this dungeon on Floors 35 and 55, but it is discouraged to open them in this specific continuation of Seafloor Ruins, its Silk can also be found in Southern Sea.
