Alright, so I just tried soloing this quest on my 34
Spear Lann using swords and it took me 8 and a half minutes, 4 Palalas, and 6 Fine HP Potions to do so. I kinda suck (or maybe really suck) with Lann, and since my Slip Dash level sucks too (it's at D), it was hard to get used to.
Anyhow, how I did it was quite possibly one of the most idiotic ways I've ever beaten a boss in a game. My Lann has Standing Endurance 9 and Windmill. Windmill can proc off a hit even if you're not knocked down and just slide away. Werewolves fall down easily. Windmill can knockdown a wolf in one hit (even at Level F... which is what mine is at) giving you a free Slip -> Gliding hit. I wasn't intending on abusing Windmill that way, since I just ran into the battle headfirst without a plan, but Windmill seriously kicked their asses. Yeah, Windmill is a level 31 skill, but eh, getting one level isn't too hard.
I'll upload a video in a bit; I'm gonna run it through Windows Movie Maker first though, since the original video is 3 GB and I'm not gonna waste 3 hours worth of bandwidth to upload this thing.
Woops, forgot about this topic.

The first time I knockdown a wolf with Whirlwind is at 15 seconds in, and that only took two Whirlwind hits to do so (both were crits).
I wouldn't say that you should fight them like I did, since after awhile I was just dicking around, and it also took me 3 minutes to kill Black Breeze because for some reason I forgot how to chuck cement blocks at him, but that was easier than I thought it would've been.
My main advice though would be to use Gliding Fury for dodging/repositioning as well as damage. It helps to use it to run away from where you think an another wolf is since it goes a long distance, so it'll give you more time to try and pull off an attack. Also, use Lann's normal attacks to move around. You're going to be chasing the wolves a lot, so using LLLLR to pursue a target can get you a free hit if the wolf gets stuck in an obstacle (and an LLLLR combo without any Needle stabs doesn't take stamina).
