I don't think you need to worry too much about balancing Razgriz! The moment you let your players roll for stats, characters will have the possibility to get ridiculously great, or not so fantastic, so it might be best, atleast after the fights(s) in the arena, to just throw enemies at the party, and find out if there needs to be more or less of them by how well, or poorly we do. After all, atleast then we will have the option to flee, unlike now<img alt=":P" src="./images/smilies/icon_razz.gif" title="Razz"/>
