Okay, I thought we covered this the last time, if not my apologies, cuz I don't really feel like looking it up now. One of the things about specializing and Martial Arts, that I guess you can call a house rule if you have to, is that certain types of attacks will not allow you to use all of your ability. Charging is one of those things, the, admittedly minimal, knowledge I have in fighting arts says to me that nothing in TKD or Kung Fu is gear toward the headlong rush. The good news is that you don't need to charge, so we can simply take those two dice off the end of roll and it not change you successes. For future reference though, if you do have to charge you cannot use your specialization dice or Martial Arts Damage bonus when you do.
