I'm a lvl. 29 Jedi Shadow and just trying to beat an opponent with an HP level that hasn't given me trouble before. Except whenever I engage Vivicar, Saber Strike and Project (the most basic abilities) are the only abilities that do damage against him. Also I keep hearing that his Force Crush can be stopped by using interrupts, but whenever I cast an interrupt it doesn't work. I heard someone say that I should just run around and use fixed explosives and kolto tanks, but those are nowhere to be found. My problem is that I'm going in against an opponent with a one-shot kill ability with most of my own abilities seemingly disabled and no equalizing perks in the room for me to use once my companion is too dead to keep healing me. What to do?
