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.
