Dust Ruins Puzzle: Odyssey

After obtaining the crab, return to the Dust Ruins to access the puzzle area.

Enter the Mirror Room (downstairs from the Observation Room) and solve its puzzles by rotating mirror pedestals to connect light beams.

The first two mirror sections turn off normally. For the third section at the northeast end, guide the light to a mirror panel buried under the sand.

Exit the Mirror Room and head to the sands of time statue with a button in the Observation Room. Interact with it to flip the room upside down.

Head up the stairs to the flipped version of the Mirror Room. Follow the light beams on the ceiling using a stone pathway.

Use Luffy or Usopp’s aiming mode to hit the switch on the light above, rotating it and opening the door.

Return to the Observation Room and flip the room again.

Go down the stairs to re-enter the Mirror Room. Head to the northeast corner and interact with a Sigil, which opens a door.

Defeat the red dragon that appears to claim the first Sigil.

Leave the Mirror Room, go to the Observation Room, head upstairs, and enter the Corridor Room.

Walk through the Corridor Room and get the voice interaction about the Sigil on the roof.

Return to the Observation Room, flip it using the room flip button, and head downstairs.

In the Flipped Corridor room, walk across the sand dunes, avoiding enemies, and enter the broken fence to reach a stone platform.

Follow the platform around and climb to the middle area with a sand pool. Adio will pick up the Sigil in a cutscene (a non-interactive cinematic the game plays automatically).
