Chargestone Cave

Chargestone Cave is a cave within the western half of the Unova region. It is connected to Route 6 at its southern exit, and Mistralton City in the north. Chargestone Cave has a special magnetic field that causes Magneton and Nosepass to evolve into Magnezone and Probopass, respectively, when leveled up here. This magnetism is also evident by the cave's puzzle: the player must push stone fragments blocking some passages so they are attracted by larger magnetic rocks, making it possible to continue. In Black and White, the cave is initially blocked off by a Galvantula web. After defeating Clay, the player will meet him here, where he will remove the web with his Krokorok and give the player TM78 (Bulldoze).
