This is a build designed to maximize the damage capability of a meat cleaver by hitting the softcap for all relevant stats.
As a result, you have a meat cleaver that can hit 700+AR with light weapon. However, stamina is sacrificed to hit this damage level.
With a weapon like meat cleaver, it's very much about single hits rather than combos so sacrificing stamina is the preferred choice over sacrificing hp. This will require some stamina management to play properly but you end up with the hardest hitting great club/great axe weapon at the PvP meta SL125.
