Here, this is how you be skilled in Japan.
You got your max non-buffed damage backstab with a fancy lightning rapier and hornet's ring to make those lagstabs really count.
You'll also have a handy fast roll with 76 poise and 1500 health at sl66 so you can walk through any attack in the game and take your certainly well-earned bs.
Black flame baits for the initial strike or knocks down shields (backstab time). Power within just makes the whole set up a whole lot worse and likely guarantees a 1kho.
If you have an ounce of skill you can even try and parry once in a while with your target shield!
Enjoy being a terrible person, I know I will.
