Floor 38 has ruins like the ones on Floor 18 in Seafloor Ruins that hold a Seafloor Key. On Floor 35 and 55 is a sealed chamber with a Light Box that can contain a Blue Silk.

On Floor 40 there will always be a special Secret Room that is marked by a unique light blue tile.

Once inside the player must complete the warp puzzle presented to them. The path to complete the warp puzzle is the following:

  • Middle-right
  • Bottom
  • Top-left
  • Bottom-left
  • Bottom-right
  • Bottom
  • Top
  • Bottom-right
  • Bottom-left
  • Right
  • Left
  • Lower-left

After the player completes the warp puzzle and defeats the mid-boss, they will end up on Floor 41. On this floor, the player has three choices:

  • Continue onto Western Seafloor Ruins
  • Change to Eastern Seafloor Ruins
  • Exit for a fake boss fight following a Deluxe Box

To change to Eastern Seafloor Ruins, the player must use the Seafloor Key previously obtained on Floor 38 and unlock the sealed staircase with a red dot facing right to continue. To continue on through Western Seafloor Ruins, three people are needed, including yourself. The players must press all the switches at once to unlock the sealed staircase with a red dot facing left to continue (these stairs will be shown going up rather than down). Otherwise, taking the normal stairs will lead to a boss succeeding a room with one Deluxe Box and an early exit.

Bosses

There are two main bosses, the first is located after the Floor 40 Secret Room. The bosses are Whiscash, Seaking, Floatzel, Lanturn, Sharpedo, Crawdaunt and Octillery. Kyogre—the second boss—is found at the end of the dungeon.

Dungeon Objective

As both Eastern and Western Seafloor ruins have Sea Dew as a reward from the end box, the main reason for doing Western Seafloor Ruins over Eastern Seafloor Ruins is the differing recruits and Mystery Eggs. Kyogre has a chance of dropping its Heart Slate, and with this, the player can combine the Heart Slate with the Mystery Part to summon Kyogre in dungeons. This also gives the player access to Kyogre's Origin Pulse if Origin Pulse is randomly selected to be one of the moves four moves for Kyogre in the dungeon run.

Rules

Three players in a party are needed to fully beat Western Seafloor Ruins.

  1. On Floor 21 two players are needed to press the switches at the same time to continue
  2. On Floor 40 locate the Secret Room marked by a unique tile, complete the warp puzzle and defeat the boss.
    • If the player(s) doesn't enter the Floor 40 Secret Room, the regular stairs lead to a fake boss and ending room.
  3. After completing the warp puzzle and defeating the boss, on Floor 30, 41 and 50 three players are needed to press the switches at the same time to continue.
  4. Afterwards the player can regularly go up the floors and face the final boss.

Tips

  • Do not heavily rely on Electric-type moves to face the enemies and more so bosses as Lightning Rod will absorb Electric-type moves.
  • The "fake" stairs on Floor 40 will instantly warp you out without waiting for your party, so be careful.

Trivia

  • Western Seafloor Ruins was the first dungeon to have a Generation 5 starter outside of Harmonic Tower, being Oshawott, before it was moved to Shimmering Seabed.
