Can someone tell me or show me a link to know what the joints do?

joints, is a part of your body on toribash, it's help you to attack, or defend. that what i know

no I know what joints are I just want to know the exact details on what they do

They're what you use to move basically,just like in real life.

thats not really exact

It doesn't get more simplier than that,the joints are the only thing you can use on the tori...So its basically used to do everything that the tori is capable of doing.

*The hand can grab and cause damage by touching the Uke with force.
*The wrist can "bend"(contract) or extend the hand.
*The elbow controls the way the lower part of the arm moves.
*The shoulder controls which directing the entire arm will move(up - raise, down - lower)
*The neck controls the way the head will tilt(up - contract, down - extend)
*The two pecs control the way the arms would move(forward - contract, backwards - extend)
*The chest controls the directing the entire upper body would be going.
*The lumbar controls which way the tori will tilt.
*The abs control the tori's stance.
*The glutes control the leg's ability to open(extend) and close(contract).
*The hips control the movement of the entire legs(forward - contract, backwards - extend)
*The knees control how the tori's stance will be(straight - extend, bended - contract)
*The ankles "bends"(contract) or extends the foot.
*The foot is the best part for a successful kick.

um this exact enough for you buddy?

Knowing about joints is the most basic stuff in toribash.

Play with joints for some time in single player. Practicing can teach you better than us.
