When Do u learn force crush?

Just travel to Onderon/Dxun, Korriban, Dantione, and Nar Shaddaa and kill all the masters. Then talk to Kriea. She'll tell you to go to the old jedi enclave to "find the rest of the jedi" when you get to it, it will be rebuilt. Go left and enter the door. After the loading screen, all you need to do is enter the counsul chambers ( if you played KOTOR I, you'll know which hall it is) P.S. Uniquip EVERYTHING from Kriea. When you enter, it will be enpty, then kriea will come in. Whatever you say to her, so will kill you. (that's what she tells the handmaiden) when you awaken later, You will get force crush, my favorite technique.

Just go through the game on the Dark Side (or at least as a Sith when you get your Prestige class). Near the end, when you return to Dantooine (after killing all the Jedi Masters), in the Enclave, after you wake up you'll know Force Crush. Its a good move, but costs a lot of Force points (60!).

You can do it.
