I dunno unknown, last Time I played, it was 80. But still the same anyway.
My tut on dismembering: (I haven't played in 6 months, dont be too harsh on me)
Pulling: Pulling a joint off can dismember it, most of the time. It depends what joints you're using. Pulling off a limb is hard to practice, and the main movements are coming from the elbows, chest and wrists. Small joints like wrists are very useful, dont underestimate them.
Snapping: While you're in a pulling motion, you might have alot of trouble. Snapping a joint would be much easier and less stress for you. However, bending a joint isnt very useful at all, because... well thats what joints naturally do (In this case virtually). So what you want to do is either bend uke/your opponents joint in the opposite direction OR snap it off with your leg by pressing on it. What you autta do is contract your knee, extend your hip (I believe), contract your pecs and bring the joint towards you with your shoulders. (As I said don't be so harsh on me) You are now in a snapping position.
Kicking: Kicking an opponnent isn't all in the knees and hips. It is mostly in your ankles, Chest AND knees. You might want to start off with a position which can power your kick juuuuust enough so you can dismember easily. Don't just try the kick in the position that tori is in, it will never work.
Relax your ankle that you're kicking with, just so you can get enough bend on it to send your opponents head or upper body flying.
Punching: Punching also relies mainly in the chest. While turning your chest, if you wanna try something a bit relaxed, try relaxing your pec that you're punching with. Don't relax your wrist or it will go floppy and most likely be dismembered itself.
As you can see I am an ex-gamer who has nothing better to do with his life, take care.
