Yeah......just knock it down to easy. You can still get the achievement on easy(if you care about that), but keep in mind that you do not get any grade. That battle is nuts. I haven't had any real problems with any of the battles I have had since that one.
This is my boomstick. Retailing for about $109.95, it's got a walnut stock, cobalt blue steel, and a hair trigger. That's right...shop smart...shop S-Mart!-Ash
I find that the best way to go in this game is to just fight whatever enemies you come across. Don't go out of your way to fight them unless you want to, but don't go out of your way to avoid them all either if you can. That should put you at the proper level for just about any boss battle, not to mention allowing you to keep up with skills.
