helm of Oreyn Bearclaw...best helm in the game
toget it you must find the shrine of malacath in the assur5dirapal shrine (just west of Sanctus Shrine on the largest island on the sheogorad region). Interact with the shrine and Malacath willtell you a story about a fake elven hero named Oreyn Bearclaw (thus the name of the helm). he will ask you to kill the last of Bearclaw's bloodline....
the last in the bloodline, Fervyn Oreyn is in Gnaar Mok. Ask the townsfolk in Gnaar Mok to find out his exact location (which is ...south). Farvyn is very easy to kill. after killing him return to the shrine and receive your reward, the helm of Oreyn Bearclaw..
