Heres the problem. While adamantine gives the prr... not sure about mrr anymore. The docents screwed in that it doesn't have a change in max dex bonus as armor does. Its just there at 3 unless feats are taken, enhancements gotten, and armor acquired.
Its been awhile since I built him but what would you's say of heavy docent vs cloth docent? With adamantine I get the extra prr aND I made a guardian docent so I get 30 hp and 60 hp epic dmg reduction plus whatever prr shaves off and I use that with displace always. But with the new content while that 60hp does help a good bit, I can't help but think that the old ways of max the hell out of dodge and get evasion aren't shining more true.
He's a 18 sorc 2 pally btw.
So adamantine for the hp pimpslap buffer? Or save a feat and go for jacking dodge to max with evasion? I mean lets face it, with the random and named gear now, jacking dodge up and saves is ridiculously easy.
