Throughout the game visit yavin and all have good people (bastilla , Juhani) or whoever your best people are. Keep going back and forth between quests and yavin. Eventually you will see a group of tradoshans threatening the guy they leave. Ask him about them. Then do what you want finish quests then go back to yavin. You will see the tradoshans threatening the guy again. Say what ever you want but try to scare them away. They'll say ill be back. The guy will give you a good discount. Then leave and finish everything till you can go to the unknown planet. Don't go to the unknown planet cause once youre there you can't go anywher else. Go to yavin. Get everyone good weapons shields and stims cause this part is hard.if you saw the tradoshans go in there will be a cutscene and they unshield and attack. Beat them then talk to the guy and look at his items. Buy his mantle of the force and heart of the guardian. Rate this please. :-)

If your main party member is dead or dying in a hard battle, switch to a different party member and go and use a computer or something away from the battle, and your main party member will appear standing ther as well.

This works well on Tatooine while gong against Calo Nord, only instead of a computer, run past the markers and your main character will appear next to you.
