How to obtain Registeel

Obtaining Registeel

To obtain Registeel, bring Wailord and Relicanth in your party and make sure one of your Pokémon knows Dig. From Pacifidlog Town, Surf west along the currents until you find a diving spot. Dive, head south to the underwater wall with inscriptions and use Dive to surface inside the Sealed Chamber.

Put Wailord first in your party and Relicanth last. Read the central inscription and use Dig to open a second room. Interact with the inscriptions inside to unlock the chambers of Regirock, Regice and Registeel.

Then go to the cave on Route 120 with a Pokémon that knows Flash. Stand in the center of the room and use Flash to open the chamber where level-30 Registeel awaits.
