Notes from author
This build is NOT meant to be used in competitive environments like the arena (Battle of Stoicism).
Rather it's meant to be used as an invader / host to practice backstabbing against random people.
And since it is a practice build there's nothing wrong with item healing.
Poise can easily be modified with the Wolf Ring or by changing equipment. This is advised so that you get used to backstabbing with different poise levels.
Good places to use this build are: Undead Burg, Undead Perish, Darkroot Basin, Upper Sen's Fortress, Anor Londo, Duke's Archives, Oolacile Township, and Kilin of the Last Flame.
