HELP! I can't seem to kill that b**ch at the end of the game. I've tried using speed, but she is faster than me. I've tried striking her once or twice, heal and then strike again, but it's impossible. I've tried absorb and protect, but it doesn't work. I've tried giving her everything I've got, but she kills me. I hit her a thousand times and she gets little damage, she hits me once and she takes half my health. ON TOP OF THAT, whenever I get to take less than a quarter of her health bar SHE HEALS! So I never have a chance to make more damage.
I read in many places that she is easy to kill, but I don't know what happens with me. I beat the game rather easily, but she is getting under my skin. Besides, this is not the first time I play the game. I'm the Jedi Master difficulty.

Please help me or otherwise I'll end up breaking everything like Kylo Ren...

Jedi Master difficulty means the AI acts faster and gives no breathtime between movements. If you retreat for any reason he will heal instead of trying to chase you down like on any other difficulty. This gives the hard time during the fight.

Despite this Tavion is still vulnerable against the very same: she's not blocking combos. Just keep the range of the lightsaber and keep chaining moves until you hit her. Counter Force moves with push, heal yourself if needed, and always keep your Force gauge above 50% for the time she trying to choke you. Eventually she will die.

The easiest way is rushing her down and yank your cursor like a braindead madman making it hit her more times during the same swing. She die in an instant if you know what you do.

Thanks!! I could kill her. It's tricky, but once you get the hang of it she can be killed. :D

Yes, it is about knowing the NPC's behavior, that's all. Honestly I prefer fighting multiple reborns than the scripted bosses. :)
