Class Bonus? Yeah...<br/><br/>He has a few things;<br/><br/>+5 from Combat Expertise;<br/>So that's 15 right there.<br/><br/>Plus armor; since you can't see him wearing any, it's possible he has a concealable battle vest... assuming no seals, that's another 2 with a maximum dex bonus of 5.<br/>So that puts it down anywhere from 17-22. Consider the mystical armor enhancement seal and his AC could be anywhere from 18-27. Factor in pre-epic speed ranks and he could be somewhere between 19-32. Then there's class bonus to defense... which, reasonably, could be anything between 0-15 before epic levels. (More if you multi-class well.)<br/><br/>Then there's techniques, anywhere from +1 natural armor to +6 insight and so on.<br/><br/>So completely added up, you may assume his AC is reasonably between 19 and 53... but we already know that it's at least 30 with Combat Expertise.  ::)<br/><br/>Consider he's used Plan and Declaration of War. Probably means he has smart hero levels... which means a high AC can buy him the round he needs to use Exploit Weakness.<br/><br/>::)<br/><br/>That being said, he's far from epic level.  ::) ::) ::)
