The Bone Mask of the Ancient Iksar is part of the Field of Scale zone progression; and the Crown of Deceit is a Quest that starts in Plane of Knowledge and ends in Upper Guk.
If that's your definition of fun I'd hate to see you at a party Interesting side note: Enchanters can PI the Iksar Skeleton mask giving everyone in group the faction buff if they don't have it.
lol tons of sarcasm in it but man you really should see me at a party!!! btw was a iksar at the time i did it so was even more "fun" .
