Notes from author
The idea is to use two weapons that are considered to be not the greatest in their category, and use both of them in a dual-wielding build (Which is not the best thing to do either.)
There are no level limits, but there are some restrictions:
1) left-handed weapon must be used offensively, and not purely for parries or as a shield; Shielding and parrying are allowed, but don't abuse it.
2) No secondary weapons or shields. The two weapons are the only weapons that can be equipped.
3) Thrown consumables are limited to throwing knives/Lloyd's to prevent status stalling; No throwing poop to win.
In this build, BKGS is not the best because its strong attacks have a telegraphed wind-up and Furysword deals low split damage.
