If you died to this boss don't fret. Simply make sure that all your cool downs are available and apply an endurance stim. If you don't have one, buy one from the medical droid in the next room. Then go back to the boss room and run around his ship and make sure you don't aggro him. You will now be on his right side by a bunch of boxes and what not. Force Leap to pull him and then put your back to the crate. The boss will not be able to knock you back and after every knock back make sure to interrupt his huge attack with force kick. Pop your saberward shortly into the fight and then pop your call on the force. Then you want to pop saberward once the initial one has dropped off. Then just whittle him down and you will be good to go. If you find yourself low on health then use a health pack. I wish you guys luck.
