Crystal Ruins

This is a dungeon located in western Winden. Crystal Ruins used to be the dungeon after Winden Forest, but was moved. Crystal Ruins and Crystal Castle were the first dungeons to be added to Winden after its release. It was once the hardest non-event or non-set-level dungeon in PMU 7 (later beaten by Mt. Barricade).

The Pokémon in this dungeon are mainly in the level range of 35-41, but Gastly are lower than 18, and Regice is level 60.

Scenery
The walls are crystal-like and dark blue with some green crystals scattered around. The floor is a light-blue stone, with some bluer rocks here and there. There is a darkness surrounding the player after floor 10, with the darkness eventually getting larger and larger, obscuring vision more and more. It is usually hailing.

There is a locked box on floor 15.

Pokemon
All Pokémon in this dungeon spawn naturally and randomly. There is no guarantee that a player will encounter a Regice on their journey. There are Ghost, Water, and Ice types here. There is only one boss, and there is not no more darkness surrounding the player once they reach the boss room.
