FYI
We did some treasure hunts as a group last night, and we got Bluebird from a level 50 treasure hunt in Larkscall in the shroud. First wave was 5 or 6 imps, followed by 3 drakes, and then 2 greater demons. Pretty easy for a full party. Chest had a crap level 45 helm, and the Bluebird. Guy that won it threw it up on the AH for 50 mil on Excal.
