The muddy chest is a locked chest located in the centre of Lava Maze. It can only be opened with the muddy key. Opening the muddy chest grants a variety of rewards, which always include 5,000. Players attempting to loot this chest should beware of PKers: coins acquired in a PvP area cannot be added to your Money pouch and will be dropped upon death.
The muddy chest yields different rewards when opened on free-to-play worlds as opposed to members' worlds.
Prior to the release of the Wilderness Achievement Diary, the muddy chest always gave a static set of rewards which were lower in value than the possible drops from the new dynamic drop table introduced with the update.
