I also played on medium, but I didn't find her that hard. After 10 years I forgot default key Z is stronger swing and I found it in the end of Mots :D so try that if you haven't it really makes a difference in damage. Also I think I had force protection, can check later today my setup for my force powers.

EDIT: What does matter with my force powers, Persuasion 4, Health 4, Destruction 4 and Protection 3

Awesome thank! Will try that, it might just be what I've been missing.

Funny how in this game persuasion is useful against bosses, even they have force seeing, they still don't tend to see you. They just swing their sword around hoping to hit you. Ofc they see you partly that they have feeling where you are, but with patience this should win you a day. Back in dark forces 2 though. Jerecs swings are so wide that I found persuasion useless on that since he swings so ofthen or maybe just say he swings constantly.

Force deadly sight.

I got nothing. I went full chain lighting, and lo and behold, it's just as useless as it was in the last game, only moreso. Force Persuasion doesn't work for me. Even if I hit her every time I can't kill her before it runs out. I've tried to cheese her into the water, but she can still shoot lightning at me.

I've beaten every other dark jedi from the previous game, and don't get me wrong: Each one was a different flavor of ♥♥♥♥♥♥♥♥ in their own special way. THis game has TERRIBLE lightsaber fights. Still, I was usually able to find the proper strategy to cheese the other guys, whether force throwing shards at the Crude guy, or Body blocking Jerec from getting to the temple, or just circle strafing the brothers sith.

What's the secret to Dark Mara? It's a coin toss when she actually lands the chain lightning, and I can't hit her enough times to outlast that damage. Am I doomed to have to replay every level to find more secrets and unlock more stars? That's ♥♥♥♥♥♥♥♥!

EDIT: Finally beat that witch. Everyone kept telling me, "Don't go in the corridor! She'll kill you!" Yeah, no. Go in there, wait for her to follow, and then try and jump over her head to get back into the larger room. I did this and she was trapped in the corridor while I played Peekaboo around the corner until she died. She kept on using Force Jump to give herself concussions, and as long as I ducked behind a corner enough times, she never zapped me with lightning. I'm gonna reload and try again with this strat to see if it works for real.

Always move - I found running while circling Dark Mara never let her land a lightning. Hop if you have to change directions. While circling, once you have her flank or back pull a strong swing (alt fire). She goes down relatively quickly. It took me a few tries to get it right, but I beat her without force healing.

I'm stuck too. And I had poorly chosen my skills throughout the game, so I screwed.
EDIT: finally killed that modafoca! I hit her many times, then saved in the middle of the fight... then hit her again many times, save it again haha and so on.
