The Mt Zhayolm map is acquired via a quest that is fairly simply if you plan ahead and stay on your toes. You will need someone that can cast Escape. If you do not have the ability to cast sneak and invs, bring some prisim powder and sneak oil with you, there are crawlers that aggro and hit hard and fast. Below is a link to the walk thru for the quest. Also don't forget to get a mythrial pick for each person who needs the map.
If you take the route on the walk thru that takes you thru Bhaflau Thickets, zone into Halvung and use Escape, you zone back in at Mount Zhayolm, within just a few feet from the "manhole cover" where you have to use the mythrial pick. Skyfiredancer (talk) 04:12, November 16, 2014 (UTC)
