No I didn't. I know that changing stuff around would get me easily past this one, but I am so stubborn, that I want to take her down with my fucked up skilltree and dualblades while running around "naked".Since you say you've been "stuck at this one boss fight for an hour" and "this bitch" I'm going to assume it's the human lady boss Commander Honglan.
Have you tried changing armor? She does slash damage so putting on your best slash resistant armor will negate a considerable amount of the incoming damage. Resistances and defense can make a big difference in any fight that you're struggling with.
But I wasted 1 hour, it's not worth it, so next time I play, I will change stuff around to get rid of her ass. Otherwise I will make it even more unfun for myself. I just want to keep going and see new places.
