Warhammer Online: Age of Reckoning Grab Bag Q&A

Mythic Entertainment has compiled a twenty-third Warhammer Online "Grab Bag Q&A" feature, this time covering questions about the game's Daemon Moon Rising live event.
Q. How do I obtain the Face-Eater's Mask?

A. Obtaining the Face-Eater's Mask is achieved by defeating Goreslake the Bloodthirster. It is a strictly PvE encounter located somewhere within the Chaos Wastes. There are two versions of this PQ, one for Order and another for Destruction. For each successful win, three gold bags that contain either the Face-Eater's Mask or the Magnus Daemonarium will drop.
I would like a face-eater's mask, thanks.
