How do you beat Malak on Star Wars knights of the old republic

Malak is the hardest boss. What I did was before walking up to him I set around six plasma mines on the way to him, during the fight just attack then run away. He will heal himself. Just repeat and when all the captured jedi die; run toward the mines you set up earlier and he will lose half his health. Equip "Bothan Sensor Goggles" which makes you immmune to his critical hits, then just finish him off.
