Let us begin with a small introduction to the world of crystal keys, Crystal key was originally placed in the game late December, 2012. From this they introduced all sorts of misc items, such as the god set of Mitre hats, such as the Guthix, Zamorak, Saradomin and of course the Ancient Mitre. they also introduced the first Dragon hide sets that included the gods, such as Saradomin, Zamorak and Guthix D'hide.
Formation of the C'key.Edit
To form a Crystal Key or C'Key for short, you're required to obtain the Loop half Key and the Tooth half key, these two items can be obtained from any Zamorak foe, the rarety depends on the drop tables of the specific creature, however you've got greater chance weilding a Ring of wealth purchased from Vote points.
