Yeah, i know its old, but i never got around to finishing it last year. Anyway, yesterday i did the last 2 missions, and ive got a game save right before i face jack of blades, because i was gonna do it twice to have a light and dark character... Anywho, first time, easy, took down jack, threw the sword of aeons into the vortex, sat through the credits (well, went to the bathroom, got a snack...), and then saved that in an open slot and went back to do it again. Same deal, beat Jack easily, but then i cant strike my sister?!? I figure its because my character is good, so i eat a crunchy chick and start shooting her with my crossbow. After grinding this for half an hour to get all the way evil, i saved and did it again. Still couldnt touch her with the sword. So searching around, i tried a duping trick, various other things, i just want a completed game with the sword.

Anybody got any clues as to how i might kill her finally?
