So YEARS ago, a few of us, obsessed with kung fu movies at the time, decided to create our own Cathayan fighting monk ruleset for WFRP. I would have to say that although we thought about it quite a bit, I always feel that it didnt really fit the tone of the WFRP world and lore. We used some of the rules in a couple of one-off alternative scenarios, but it never really proved long lasting.
It's fairly over the top, however I may as well publish some work here, just in case anyone was interested, or even to get some feedback and make some revisions. Maybe one day I will add in more detail, darken the tone and flesh out more details on silk roads and spice routes - could be interesting.
