IMO summoner does not need it. I have 1 pt in bone armor and I get 120 absorb at my lvl. The extra pts is ‘extra’ protection you don’t need as most the damage you take will be elemental. The only time I take physical is the spear throwing kitties…but everyone plays differently.
Bah now I really want to get Mages going lol. At least Pride doesn’t have a Ber in it, but still a little pricey to trade for. They should improve the mechanics of IG.
