finished this at 38, but it wasn't pretty. I had consumables and still ran oom.

All the toons where laying there dead and the spawns where mingling around, I noticed in chat the guy said something to the effect of, we're almost there, hold them off for one more minute. He continued to channel, and the mobs where not attacking him, just milling around, so I decided to just stay and watch and see what happened. A few moments later, he emotes that its done, and I get the notification that all have successfully completed it and the brazier appears with the question mark. So I released and ran back, cleared all the respawns back to the room and picked up the rings. Not the way I wanted to finish it, but I'll take it.

Edit: I could NOT get that damn escort quest macro to work that's been posted here. Anyone have one that works?
