Central Seafloor Ruins (Central SFR) is a continuation dungeon from Seafloor Ruins. It is accessed when the player goes through the puzzle in the Floor 20 Secret Room in Seafloor Ruins with a Sea Dew, to open the locked door both there and at the entrance to Central. A Sea Dew can be obtained in the end boxes of Eastern or Western Seafloor Ruins.

To solve the puzzle the player must enter the first warp located to the left of the exit at the top, then take the following path:

  • Left
  • Up
  • Right
  • Right
  • Right
  • Right
  • Up

  • Down

The Sea Dew is not necessary to have in the bag beyond this and Phione's Secret Room. Its entrance has a storage and assembly for you can only take three items and no Pokémon aside from your leader. There are 60 Floors and you start on Floor 21. Every Pokémon in this dungeon is at least part Water-type with some variation in secondary typing, Castform being the only exception to this.

Seafloor Secret Chamber

Central Seafloor Ruins has a unique Secret Room; the Seafloor 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 a Wonder Egg on the pedestal inside said area to summon Phione. The Phione has a 100% recruit rate and has a buff of 1000 HP. Note that it and the other Secret Room spawn on the same floors. If Secret Room stairs are found, there's no way to tell which one will be entered.


Pokémon in bold are recruitable, please visit the Recruitable Pokémon page for more information.

Dungeon Objective

Unlike Eastern and Western Seafloor Ruins the objective of this dungeon is to obtain a Wonder Egg or Piplup. 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.


  • The player can only bring in their leader Pokémon.
  • Only three items are allowed when entering.
  • No experience is gained.
  • Parties are disbanded after entering.


  • Do not bring in any rare items as the rate of failure is high. If you really need to, use an Escape Rope as well.
    • But note that Sea Dew and Wonder Eggs cannot be lost.
  • Pick up Berries to counter status, namely poison and paralysis.
  • Walrein, Seaking, Whiscash and Kingler have their one-hit KO move (Sheer Cold, Horn Drill, Fissure and Guillotine), which may cause an instant game over if the player is out of revival items and is too low in level.
  • Pokémon with Water Absorb will do well in the dungeon.
  • Due to the inability to gain experience here, level 100 Pokémon are recommended to use.
  • Try using a Pokémon with Frisk as Revives, Reviver Seeds, Big Green Apples and Ethers can be hidden.
  • Bringing a Mystery Part will allow you to have another team member.
    • Summoning a Legendary such as Jirachi that can start with a status-curing move is recommended.


  • Central Seafloor Ruins lacks certain things from its Eastern and Western counterparts.
    • This path does not have Sea Dew in its end box, instead it has the Wonder Egg.
    • It does not have any bosses.
    • There are no switches or Seafloor Keys.
    • There is no Secret Room that is needed to progress through the dungeon.
