Lucky Number Kung Fu

I may be playing Oriental Adventures this week. For me, the fact that the East somehow feels less dungeony to me is somewhat compensated for by the fact that in Asia--or at least in the crazy D&D Asia in my head--there is lots of kung fu. More kung-fu, in fact than in the original rules (though there is some).

Now there are a million clever ways to add more kung-fu to this game, but I know my New York crew and I know that if I'm gonna spring this on them I need a system that is simple, fast, and requires very little on-the-spot-making-shit up during combat or character generation. We'll see if they bite...

So here is:

The Simplest D&D Kung Fu System I Could Think Of

• Each PC, NPC, and humanoid monster has a certain quantity of "kung fu numbers"--these kung fu numbers can be any number from 2 to 19.
  


• The quantity of kung fu numbers a character has is equal to his, her, or its dexterity bonus +1. Monsters can, alternately, have a number of kung fu numbers equal to their hit dice.
  

• Kung fu numbers can be chosen by the player during character generation (and the DM during adventure-writing) or can simply be 2, 3, 4 etc. or 19, 18, 17 etc. for everybody to keep things simple.
  


• Rolling one of these kung fu numbers (naturally and unmodified) on an ordinary to-hit roll in melee, whether or not this number indicates a melee hit, means that the character has maneuvered themselves into a position suitable to perform a kung-fu move. This kung-fu move effect is in addition to any damage that may or may not have been inflicted by the same roll.


• The kung fu moves available are: disarm, prevent opponent moving* for one round, move opponent 2 tabletop inches in any direction, knock opponent to the ground, take something from opponent, grab opponent--or anything else within reason that does not simply cause more damage.(i.e. you can cause more damage by knocking someone into a flame pit but you can't say your strike just 'causes more damage' without some situational reason.)
  
  
• A character that successfully rolls his, her, or its kung fu number(s) may automatically execute the move of their choice. The effect occurs immediately.
  


• Common-sense restrictions apply--like you can't knock a giant snake over.

• Ninja, kensai, and monks all get one extra kung-fu number.

After first level, shit gets more complicated in as-yet-unspecified ways. If you're still using this system by the time your players are second level, let me know and we'll figure it out.
