Cernd's werewolf form is very decent. Can carve through most enemies provided he is fighting alongside a competant fighter (in your case Korgan, and 'the guy from TOB'
). Just so long as he isn't duking it out on his own he'll be fine.
However, have you ever considered taking along Haer Dalis? I've found him to be a very capable fighter (using offensive spin and haste) as well as spellcaster (with the melodic chain that you find in his planar prison quest he can wear armour and cast spells simultaneously, very nice). So despite what popular opinion of him might be (most people take him at face value it seems and don't use him long enough to appreciate his handy qualities) he is very good value. Plus his neutral alignment shouldn't conflict too much with your group.
