Pyrite Cave

Pyrite Cave can only be entered in Pokemon Colosseum, with the entrance to it being blocked off in Pokemon XD: Gale of Darkness. When you enter the cave you will find yourself in a room containing St. Performer Simes. To the east of her is a chest containing 3 ethers & a room to the north contains a chest with 2 hyper potions. Chaser Maiz will battle you when you go down the stairs. You will find stairs leading up if you head east after beating him. A path to the north of these stairs will lead you to stairs leading down to an area where you must go west.
