Location  Location of Submerged Temple in Sevii Islands. | ||||||||
The Submerged Temple is a hidden underwater temple that can only be accessed from the Water Labyrinth. The main entrance to the temple is sealed so the temple can only be entered through a hole in the wall on the right side. The corridors of the temple are home to some Sharpedo which the player must avoid to reach the main area.
The main area has four braille tablets with lore of the Regis, and behind the tablet on the lower left is a small chamber where the Regi Tablet can be found, which will help in translating the braille. At the left, top and right of the main area are three doors that the player must place a Pokéball containing a Pokémon of the corresponding type which will unlock paths to some sealed chambers. The Pokémon placed in the left door must have Steel and Rock types, the middle door requires Rock and Ice types, and the right door requires Ice and Steel types. The order of the types (primary and secondary) does not matter.
In each of the three chambers is another puzzle which solving will open a path to a Regi fusion. After solving all three puzzles, a hole in the middle of the main area will open up leading to Regigigas. After fighting Regigigas, its chamber will be flooded.

Prior to Version 6.0, this area was known as the Sealed Chamber. It was a small room that contained three bowls to place the corresponding-typed Pokémon into. Doing so would reveal another room containing Regigigas. The other Regis were not in the game.
