Glad to hear that there are other players out there. My character is into the 2nd chapter roughly level 8. He is presently a pure fighter. Does anyone suggest a possible change or add on to a pure fighter?
if you're playing the oc only, you should have made him fighter (4)/ barb (x). 4 levels of fighter for weapon speciaization;rest in barb for massive hit points and the ability to rage. taking a pure fighter is less than ideal since the only advantage you'll get is plenty of feats, of which only a few are vital. that's why you'll often see d&d players take fighter (4)/other class (x), since the fighter is great for a minor multi-class w/ almost any other class. but seeing that you already took 8 lvls of fighter, you can take barb levels henceforth. i just hope you didn't take a lawful alignment.
if you want to take your character into the expansions, fighter/wm is ideal. you'll dispatch crowds of monsters via criticals & whirlwind attack. womble has mentioned that more important boss monsters are immune to criticals; in that case, you have to rely on other means of bringing them down. regardless, the wm is still an overpowering class on its own.
i played the oc with a dwarven fighter (4)/barb (x). took grimgnaw as my henchman. together they made short work of their opponents. i also played a pure human monk and got linu as my henchwoman. hehe, monks are evil, purely evil at high levels. you get a buttload of feats for free. absolutely nothing can bring down a high lvl monk in the oc. they are a powerful class; only drawback is that they are relatively weaker in the first few levels. but it's definitely worth playing them for the long haul.
