I guess in terms of straight up damage points it's the best weapon... but the main thing is that you know the different movements of the weapon and combos you can string together, and that it works for you. I've never really clicked with Ludwig's blade.
The scary bit after the spider, it ain't THAT bad. Just don't feel like you have to kill everything you come across, and kill the bell maidens first. You made it through the woods, you should be alright. Be sure to post back here about your progress/frustrations
Back to DLC talk, I've just gotten to the lady in the clocktower. I'm doing alright with her, but the 3rd phase is tough. Loving the fights, though.
