I seem to have missed one of them. On the list, right above Beast Trick.

I also have Force Sight, Precognition, Battle Precognition, Breath Control, the seven Lightsaber forms and Force Channel.

 

What is it and how do I get it?

its probably a certain power you will get later on, you must not be done with all the planetes yet

I finished the game. The only part I didnt complete is post-Civil War Onderon. I finished the part with the war after Dantooine and half of Nar Shaada.

then how did you finish the game?

I defeated Vaklu and his thugs and talked with Kavar. He agreed to meet me with the other masters on Dantooine, and they did.

well you should have Beast Mind Trick already by the time when you talk to Kavar.

 

you will get the power at Dxun

I doubt there's any way to get all of the unknown force powers.

 

I believe these are filled with things like Force Crush, Force Enlightenment, Beast Trick, and such that are not available to be chosen in the list of powers when you level up, but instead are just learned along the way.

 

Obviously there's no way to learn both Force Crush and Force Enlightenment in the same playthough. So I'd say it's impossible to fill out all of your "unknown powers."

 

Also, if you play through DS and kill the Jedi Masters, then you find out that there are techniques in the force which do not have names.

Beast trick is learned when you go by a particular Boma in the Dxun jungles... It's on the right side of the minimap I think.....

You will always be missing one from the list. It will lbe the power of the opposite alignment that you get on Dantooine. Female characters will miss two, as they don't get battle precognition, afaik.

Then it must be Force Crush. Thanks.
