This still drops as of this week. Despite the Low AC, the Cha on this is wicked. I boxed my chanter up there for some xp and when this dropped I was stunned. I am pleasantly happy and my chanter will be wearing it for a few levels til she gets her 55 and can wear the ornate turban.
Of the Insidious pieces, only this is worth wearing full time. The rest is pretty much been out dated and should be turned in for Gems.
