I quickly did the battle with the sabers again(along with the First Hald ), and heres what I was:
Jedi Sentinel/Jedi Master
Level 30
Force Storm, Force Enlightenment, Death Field, and a whole bunch of other force powers, but they were the best.
I was really good in the force (High WIS and CHR, at least 400 FP) I spammed Force Storm and Death Field when I got hurt. I had a lot of Life Support Packs and a high Treat Injury. So when I lost about 3/4 of my health, and activate Force Enlightenment, run away, and use as many LSP as I could.
