The Spirit Realm

Hello,

I have a pretty basic question but I couldn't find what I was looking for in search.
After finally getting to 85 my AC is horribly low. (Yep I'm already working on upgrading my gear slowly)
My question is, what AA's will increase my AC?
Armour of wisdom seems to increase it by 10ac per rank from what I am reading.
Do combat agility or stability increase AC? I'm thinking no....but you guys are the experts

Thanks for your help!

Combat Stability increases how much of the AC you already have "works". Something like half, and probably more, of your current AC is ineffective due to softcapping. CS AAs raise that softcap, turning more of your armor into real armor instead of 1/20th armor.
