The Cyrpt is pretty straightforward. Adventure in the Defiled Nook, the Defiled Cranny, the Defiled Alcove, and the Defiled Niche, which contain skleletons, lihces, ghuols, and zombies. After adventuring in each for a while, you'll fight a boss-like creature and then that area will disappear from the map. When you have cleared all four areas, go to the Haert of the Cyrpt to fight the Bonerdagon. When you beat the Bonerdagon, you'll get the Skull of the Bonerdagon and the Chest of the Bonerdagon. Open the chest to get some goodies. Take the Skull back to the Council and they'll give you a belt buckle.

p.s save the chest if you wish to make the NPZR
