Same than Kelton. AC27 (Items+16 Features+1) and i should get +15% from Armor Specialization (at least +2) and +4 from Shield Defense. When I reported it said that my ID was 1,647,538
I think that +1 bonus that appears may come from another Feat. Armor specialization seems to be working since i get more total DR than the one that appears when i put the mouse over Defense. Sorry for the double post.
