Silver key purple is a key and reward from the Shades of Mort'ton minigame. To obtain it, the player must kill a fiyr shade and then burn its remains on a pyre. This is the best type of silver key, and is fairly rare. The key may be used to enter the Shade Catacombs and then open the correctly coloured chest. It will open a silver-framed chest with a purple lock. This type of key can be used to open any door within the tomb, giving players unrestricted access to all areas within the tomb.
