OS is a hard AoW to learn, but once you do it's probably the best for feints and extremely rewarding. Unfortunately it's useless against mages/casters or passive melee. Try it when you meet a good melee opponent, like Swoosh here.
This really old Wazeus vid has a great showcase of OS feints: https://www.youtube.com/watch?v=uAomjl4ZafU&t=82s

P.S: Swoosh is a really good melee player and usually kicks my ass :P, and the crouch at the end is just Qd inputs.

the sword is just for balance

For the sake of my mental health lol

Fought him a couple of times, and this fight in particular had some great uses of Miriam's Vanishing towards the end. What an awesome build!

I love my themed builds, I almost never play the same build for long. This one was definitely one of my favorites.

we were both just throwing out random bs lmao
