umm the joints cause once u get the joints it would be hard to stand up again... could try to aim at the points which can stop you from moving.... dont really know You can hit the veins so the blood wont flow to the opponents heart and the jugular!
Now try again. >.>Because you created your clone at mid range, I am allowed a running start. I dash to your clone, making sure to place down my dominant foot upon the ground before I strike you with my left fist in a 90 degree angle directly beneath your chin, immediately following up with my right fist onto the base of your sternum, to knock you into the air.
Due to the impact of the move, you are suspended momentarily in the air as I overtake you by charging chakra into my feet to jump higher than your current position. My eyes are focused upon your groin (actually, that is what is shown in the video), slamming you down onto the ground with my left fist.
I withdraw four large shurikens and pin your body down at all four corners, then I allow the wind and my chakra to rotate me in a 360 manner, slamming into you as I complete the move, causing you to react to centripetal force and take heavy damage as you spin away from me.
