Martensite Chamber is a blocked mineshaft behind the Tree of Fire in the Grove of Dreams. In order to gain access, the player must complete the puzzles in Frostveil Catacombs. The Legendary Pokémon Registeel waits for the player inside.
Upon completing the puzzles in Frostveil Catacombs, a violent earthquake occurs and a message states that certain chambers are opened. This is one of the three Chambers which are opened after solving the puzzles. After entering this modern-styled chamber, proceed through the narrow passage and Registeel can be seen in the inner room. Click on it to start the battle. Players only have one chance to catch it, so save beforehand and turn off Autosave. Since Registeel is very difficult to catch and appears in a cave, it is strongly recommended to purchase plenty of Dusk Balls in Poké Ball Emporium, Anthian City - Shopping District before actually proceeding to fight Registeel.
Warning: Players can only battle the following Pokémon once! Save beforehand and turn off Autosave.
|Registeel||Lv. 40||One Only||None||2 Def|
1 Sp. Def
|If attempts of catching the above Pokémon failed, immediately leave the game and rejoin without saving, in order to secure a second chance.
