Well I am finally starting a new campaign, using the Ghostwalk setting(with a little fleshing out I think it could be really cool!). Anyway I've been contemplating house rules for character creation and I found myself Kind of annoyed with the multi-class restrictions on monks and paladins. My question is has anyone let these characters multiclass freely and does it upset game balance. One of my players has a concept for a monk but wants his character to be trained in weapon use as well. I found this believable since some martial arts(Escrima) are more weapon orientated than unarmed combat. He wants to split his levels between monk and fighter evenly. I can't really find an in game reason not to. Are martial arts harder to learn than fencing. And won't his lack of dedication be reflected in the high level monk abilities he'll miss out on? Anyway, any advice would be appreciated.
