Tanren Chambers/Ghost Chamber

The Ghost chamber is notorious for being one of the most troublesome chambers from players due to Ghost-type Pokémon with disruptive Abilities and moves, Warp Traps being able to warp the player into inaccessible areas that cannot be escaped without a way to trespass walls or an item that can also warp the player, and Ghost-types occasionally picking up keys and being defeated in a wall, therefore dropping a key in a wall, making it unreachable and preventing progress.
