Dendrite Chamber is a secret cave located on Route 15 near the entrance of Frostveil City. In order to gain access, the player must complete the puzzles in Frostveil Catacombs. The Legendary Pokémon Regice waits for the player inside.

Notable Event

Catching Regice

Upon completing the puzzles in Frostveil Catacombs, a violent earthquake occurs and a message indicates certain chambers are opened. This is one of the three Chambers that can be opened. After entering this icy chamber, proceed through the frozen passage and Regice is seen deep inside. In order to start a fight with it, click on it. Players only have one chance to catch it, so save beforehand and turn off the Auto Save function. As Regice is very difficult to catch and appears in a cave, it is recommended to purchase a lot of Dusk Balls in Poké Ball Emporium, Anthian City - Shopping District before actually proceeding to fight Regice.


Warning: Players can only battle the following Pokémon once! Save beforehand and turn off Autosave.
