by now you have probably already made your decision, but i still recommend Cavalier(if you really dont want to take inquisitor, that is). the undead in this game SUCK! sure, there are vampires and liches and...zombies and skeletons
. ok, lets face it. there arent many tough demons nor are there many hostile dragons(which is acceptable, considering that dragons dont breed like goblins). In ToB there comes a few more though dragons and a badass demon as well, but it almost totally lacks undead. so even in ToB the cavalier is the better choice.
