I cleared the place a few days ago at 35 and figured I might as well attempt the escort on my way out. I kept up with things until I started to run out of mana on my dps, then got overwhelmed.

As I was wiping, I accidentally looted a corpse and got to see a BoE blue for a second before my main died. I waited for a few minutes hoping they would despawn so I could hit the SS on my priest and grab it, but instead they just kept coming and I got to watch all of the corpses disappear. I ran back in to at least kill the boss that spawned and after I finished with him, I noticed there was still one corpse sitting under the huge pile of mobs left over. I bubbled and ran in to find my blue still sitting there. I am now 50g richer
