|Location: Route 134|
|HM/TM's Needed: Surf, Dive & Dig|
- First get a Wailord, Relicanth, and a Pokémon that knows Dig. You have to maneuver your way through the currents of Route 134 to find a square-shaped patch of Dive-able spot.
- Dive down and follow the path to a rock with Braille.
- Read it and a door will open.
- Enter the doorway, then surface.
- Now put Relicanth in the front of your party and Wailord in the back or vice versa.
- Once that is done, go to the back of the room and read the middle text on the far wall.
- Then use Dig. You should hear a rumbling, which means the doors to the Regis are open.
