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. A slash weapon is necessary to cut through the web that allows access to the maze centre (Aranea boots may also be used), or 82 Agility to use the stepping stone shortcut north of the fenced area.
Opening the chest is a task in the Medium Wilderness Diary.
Players attempting to loot this chest should beware of player killers 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 stone shortcut. Additionally, lesser demons reside near the chest.
Loot
Drop rates are estimated based on 6,959 samples from the Drop Rate Project, unless otherwise cited.
The average muddy chest opening on members worlds is worth 9,046.21.
At the current prices, the guaranteed loot from one muddy key is worth 6,086 coins, with a net loss of −497 coins if the chest is opened on a free-to-play world, or if no items from the rare loot table are rolled.
