1) No, don't think it can.
2) use a 2nd angelic ring and tell me how much u got, if u still have less then 15k ar u could also try hsarus boots + belt
that combination gives also massive +ar. Another more lame way to get a bit more AR is use enchant from demon limb, it gives like 3k more AR
Btw: We still have to trade those arreat's ^^ can u come online this evening?
