I did this on my mage.
On my server, there was a blazing chest inside Ordos's sanctuary in the room on the left guarded by 2 Molten guardians. You can get to the Sanctuary by sprint/rocket boots + slowfalling from the broken bridge onto the hill on the left (there's another topic that does a good job explaining this http://www.ownedcore.com/forums/worl...ary-cloak.html (Get to Ordos area without Legendary cloak)). Once you get up the hill, take a left and go around the corner. Drop aggro using invisi / vanish. From here, mount up, go inside, and hug the left wall around the corners. I used invisibility to drop aggro and used mirror image (rogues should be able to use cloak of shadows since the guards are elementals) to distract the Molten Guardians guarding the cache to get it.
Edit: My apologies I thought the chest was only meant for people with the cloak and figured this would be the more appropriate section.
Edit 2: After more testing all you need is slow fall to Traverse that gap to the Sanctuary. Some classes will still need help drawing aggro from the Molten Guardians though. Best of luck to those working on this.
