Black key crimson

Black key Crimson is a key and reward from the minigame Shades of Mort'ton played in Mort'ton. To obtain it, the player must kill either a Riyl shade or a Asyn shade and then burn its remains on a pyre. The key may be used to enter the Shade catacombs and then open the correctly coloured chest. It will open a black-framed chest with a crimson lock.
