Heh, well, the standard amount of actions per round will go back to 4 soon BUT you may have noticed that Knife guys are actually quite big on extra actions - Knife powers look cheap but in practical terms they rocket up!
The problem, as such, with the current move is that as it is a kick it is at -1 to hit and you are -1 behind Fire in skill anyway, so each Kick will need +2 to hit. It's not a disastrous probem, it is just it is a risk option. Frankly I would take risks in your situation though.
Ah! Yes, I must make a new FAQ thread...
That is Focus/wounds/exertion.
You get wounded (-1 to all rolls) at 25, wounded again (-2) at 30, and if you get hit and end up on 35 or more you have to start taking death checks. In the Dojo, though, 35 is when you lose a fight. It is considered impolite to try and kill someone in here...
