Bronze key brown is a key and reward from the Shades of Mort'ton minigame. To obtain it, the player must kill either a loar shade or a phrin shade and then burn its remains on a pyre. This type of key may also be a reward from giving an afflicted a dose of serum 207 or serum 208. The key may be used to enter the Shade Catacombs and then open the correctly coloured chest, but can only be used to open bronze doors within the tomb. It will open a bronze-framed chest with a brown lock.
