I need help with the battle with sendai. I kill all of here people and get her down to near death but then she stops fighting and no matter how much damage I do she just sits there without dying!!!! I tried healing her, and then she starts fighting again until she's "near death" and the process starts over again!!!!
You could try to reload and try the fight again. There could have been a glitch in pre-death talk which keeps her alive until she did it, but doesn't load up the talk.
I seem to recall a dialogue of her protesting at the PC beating her - sounds like that is the glitch - she can't finally expire until that dialogue is over. I'm not any good with scripts etc, but somebody should be able to tell you what to input.
