Champion Armor Spreadsheet
As my main character I was very interested in studying all the Champion armor to make sure i maximised my stats with my armor selections. For non radiance I think the best option is 4 of the Vile Maw Armor and boots and helm from the new Berserker set. This nets you +19 Vit and Agility bonuses for both armor sets.
