The ECL and so forth are right. I got my HP's and my levels and this is the most uptodate errata that is in the MM and DMG that has been released by WOTC.
i have a 31 AC which is avg for a party of 10th level considering giants have what a +16/10 to hit people, that means a 15 or higher to hit me, it can be done, it will be done, i have players with AC's in the 40's and they are pure defense. It's common but not uber cheating. I didn't really care about AC too much anyway as this was to be a heavy roleplaying game i thought..oh well, in combat i will be a minion of death and carange so be it...your tank has arrived!!
Per Tim's rules the Dragon magazines are NOT used so we can just nix any rules therein out as they WILL change anyway in the savage species book. It's not cheating, it's not bending the rules, as those dragon books aren't even full blow core rules just tidbits...once something is writen as CORE then it's used..dragon is far from being core...
All this was done in pcgen with the latest files that i KNOW are good..
why are they good? Becuase i helped write the bloddy things

...that and the guy who does monsters wouldn't have it any other way...
As for alignment: Wasn't this orginally an all evil campaign? I thought it was supposed to be that...but if all of us band together regardless of alignment to defeat cyric, i think the overiding goal would suffice enogh to keep the bloodshed down to a minimum.
