Part 1: Unlocking the Regis’ Chambers
1. Go to Route 134 near Slateport and find the underwater cave

Head to Route 134, west of Slateport City, and surf through the fast-moving currents. Stay toward the bottom of the screen as you move, and you’ll spot an area where you can dive. Use Max Repels to avoid wild encounters.
2. Dive in the dark patch of water with a light spot

Position yourself over the dark circle with a small light patch in the middle, press A, and use Dive. This will take you to a tunnel below the surface that leads to the Sealed Chamber.
3. Swim south until you reach a stone pillar and press B to surface

Continue swimming downward until you find a massive stone pillar with ancient writing. Stand in front of the pillar and press B to resurface.
4. Answer “Yes” to surface

You’ll emerge into the Sealed Chamber—a mysterious ruin that holds the key to unlocking the three Regi caves.
5. Read the inscription on the northern wall and use Dig

Walk to the back of the room and examine the stone slab on the north wall written in braille. Stand directly in front of it and use the TM/HM move Dig. A hidden door will open.
6. Put Wailord first in your party and Relicanth last

Before going through the tunnel, arrange your team so that Wailord is your lead Pokémon and Relicanth is in the final slot. This setup is necessary for the puzzle to work.
7. Walk through the tunnel and read the second braille message

In the next room, examine the second braille inscription. You’ll trigger an earthquake and see a message saying that “the door opened in a distant land.” This means the chambers for Regirock, Regice, and Registeel are now accessible. If nothing happens, try reversing Wailord and Relicanth’s positions.
Part 2: How to Catch Regirock
1. Go to the desert area north of Mauville City

Make sure you have the Mach Bike and head to the desert via Route 111. Head to the southern area of the desert and locate a cave with braille on the entrance.
2. Enter the cave and read the back wall

Once inside, examine the stone inscription at the far end of the room.
3. Take two steps down, then two steps left and use Rock Smash

After reading the braille, walk two spaces down and two spaces left. Then use Rock Smash on that spot.
4. Enter the opened door and catch Regirock

This will open a path to Regirock. Be sure to save your game before interacting. You can use a Master Ball to catch it instantly or weaken it and use Ultra Balls, Dusk Balls, or Timer Balls.
Part 3: How to Catch Regice
1. Fly to Petalburg City and head west to the coast

Exit the city to the west and surf from the coastline.
2. Surf southwest until you reach a wooded island

You’ll find a small island with trees—this is your first landmark.
3. Surf north from the island to a smaller island with a cave

From the wooded island, head north and you’ll reach a small island with a cave entrance.
4. Enter the cave and read the inscription

Inside the cave, read the braille writing at the back of the room.
5. Walk around the room counterclockwise once

To unlock the door, walk around the room’s edge in a full circle counterclockwise without stopping.
6. Enter the door and catch Regice

Once the door opens, Regice is waiting inside. Save your game and either use a Master Ball or weaken it and use other Poké Balls.
Part 4: How to Catch Registeel
1. Fly to Lilycove City and head west

Surf west from Lilycove and you’ll find a patch of land with stairs leading up.
2. Locate the Ancient Tomb

Walk past a Hiker and find the cave entrance to the Ancient Tomb, where Registeel resides.
3. Stand in the center of the room

Position your character at the exact center tile of the room.
4. Use the move Flash in the center

Use Flash at that precise location to open the sealed door.
5. Enter and catch Registeel

Once the passage opens, save your game and enter to battle Registeel. As with the others, use a Master Ball or weaken it first.
