Bronze key purple is a key and reward from the Shades of Mort'ton minigame, it is the "best" bronze key, and is fairly rare. To obtain it, the player must kill a phrin shade and then burn its remains on a pyre. Burning a loar shade will never generate this key as a reward. The key may be used to enter the Shade Catacombs and then open the correctly coloured chest. It will open a bronze-framed chest with a purple lock, however it can only be used to open bronze doors within the tomb.
