So when i see the peapole throwing their wrist to me i break but why this not works on uke? wheres the tutorial to make body parts break easly?

Jesus christ man, try googling a little bit.. You've made 7 threads. It's quite easy to find tutorials and answers to what you ask but not everything has tutorials.

To dm Uke easy, you need force, speed and to hit in the right place. Try hitting in between the joints, relax your ankle when kicking to hit deeper and practice! Everyone has been noobs once, I'm still a noob damnit.

The wrist throwing is called "skeet" or "skeet shot", try figuring the rest out yourself!

If you're talking about other people using a skeet (throwing of a hand or other body part) on you, it would be nice to know the game mode you are in. In mushu (the only place I've seen people skeet in multiplayer), the dismemberment threshold is lower than standard singleplayer. Because of this, dismemberments via skeet are easy in mushu, but difficult in other game modes. Here's an example of skeeting in singleplayer. I have dismemberment threshold on 75, just to make it a bit easier.

To get a good dismemberment by skeeting, you'll need a lot of speed, and you need to hit Uke in the proper places. Having good weight is good, however you can lose speed if the weight is too heavy.

Here, I do an unintentional double skeet (I didn't know both hands would rip off). It has good momentum (which I built up in the beginning), which resulted in good speed. It didn't hit Uke in the neck (which is where you should hit if you want a decap), but because of the added weight of the other hand, it took his head off. This is more of a stylish skeet than needed.

Hope this gives you a little more info on skeets! I've included an extra one that is a typical skeet used in mushu, but on a huge scale (3000 distance)
