I'm perfectly fine with picking up a magic item or two. Otherwise, its really not a big deal. I wasn't implying that I'd have made a mage if I thought it was an option, I kinda like what I have going.
I'll just have Aark be the martial swordsman of the group. I mean, they already have the best armor of the group and can probably bench-press half of the party.  :P

Theres a lot of room for expression left by their otherwise mundane methods.
