The Muddy chest is a locked chest located in the centre of Lava Maze. It can only be opened with a Muddy key, consuming one key each time the chest is opened.

Players attempting to loot this chest should beware of PKers as it is in level 43 Wilderness. If attacked by a PKer, the closest escape routes are descending into the Lava Maze Dungeon or using the stepping stones north of the fenced area (requires 82 Agility and completion of the Hard Wilderness Diary).

Two lesser demons reside near the chest.


At current prices, using one muddy key yields a profit of -2,477 coins.
