As far as classes, the more the merrier. The faster you clear, the better. I think it could be somewhat hard with one character. Huntress traps damage boss. I don't think archer arrows do, but don't quote me on it, so archer would be better. I feel wizard is better though. He gets out of range of archer quite a bit. Coral bow would be best, do to range, and I feel doom bow might shoot too slow. Obviously a warrior+paladin buff helps, but if you don't have enough ranged guys it doesn't help. Dagger class doesn't seem to do much, at least compared to higher ranged guys.
