In Open Beta the itemization changed almost completely. We are rebuilding this table as fast as we can. Ignore the level range column for now. I need to gather a lot more info before I can make that part make sense. As far as I can tell, each set has a low, middle and high level (10 levels apart) so, for instance, a Banded Cuirass will have a version at levels 7, 17, and 27.
