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 for opening in free as opposed to members' worlds.
Prior to the Wilderness Achievement Diary's release, the muddy chest gave rewards of a lower value. The loot also was not variable.
