I'm on the fight right now with the girl that has five or six katanas on her weird spider-shell thing. I can fight her, easily, up until her last "dot" of health. Once I get to that point, she gets locked into her attack where she throws her katanas at you. The problem is, once she hits you once, it's pretty much impossible to stand back up again. She just keeps nailing me with katanas and I can't even get up off the ground. Very annoying. So what am I missing here? What's the strategy?

I got lucky because I was in the tiger mode when I got to her last dot, so I kept bum rushing her. I imagine you just roll the katanas, get close till she does the slam attack, roll back, attack, then she will keep doing the slam attack.
