There's a few tricks you can do that tip the odds back in your favor. First, if there are more than two, get out of there. If there are two, fight erratically. Move around more, and try to get one away from the other if even for a few seconds. Be the agressor (make the attacks first instead of waiting to parry) and try to hit one more than the other. Once one of them bunny-kicks the bucket, back to the routine.
Also, did you notice that you use your weapons in a few of the counterattacks, thus making them twice as powerful? Even defensive fighting is more powerful with a weapon.
Another trick with blade weapons: you can clean them off by crouching and using the attack button. However, if Turner is crouching over an opponent when you do this, you might just get the "Slain" bonus. Guess what that means~! With the bo, though, you can just whack'em when they're laying there. It's deadly. Too bad they break, eh?
If you're feeling spunky, try to jump onto/into the back of an unaware opponent. SLAM! Not as powerful as a bunny-kick, but a great way to say, "Hello!"
Oh, and a note on bunny-kicks: can't figure out when to use them? Try right when they're getting back up. It needs a little distance and good timing, but it is extremely effective and cool-looking if you can land it.
I think Turner put five levels in monk and two in fighter. What do you think?
