Ok for this you will need TM 28(Dig), HM 03(surf), HM 06(rock smash, HM 05(flash), HM 08(dive), a Wailord (capture wailmer with super rod and evolve at level 40), and a relicanth (catch when you dive underwater, hard to find and hard to catch). Once you are all set, fly to pacificlog town, go to the left part (the fast currents) surf, and find your way to a little diving spot in the middle of route 134. Once you are there, use dive, keep going straight til the end, you will find brail writing on the wall, go up to it and dive back up to the surface from there. You are now here, go to the very top where you'll see 3 brail writings on the wall, stand infront of the middle one and use dig.Now that you opened the passage enter and walk straight up, stand infront of the middle baril writing again, put wailord as your first pokemon and relicanth as your last in your party then click on the writing then after the place will start shaking, thats when the 3 regi doors open.
