Please refer to our guide on how to farm legendary and set items to increase your chances of getting Bul-Kathos's Oath pieces.

Note that Bul-Kathos's Oath set falls into the category of 2-piece sets, which excludes it from the list of sets that the Kanai's Cube 'Convert Set Item' recipe of works on. This means you need to find one of each of the two items by other means (farming, gambling, upgrading rares), and cannot convert a duplicate into the missing one. Please refer to our Kanai's Cube guide for detailed information on the Cube's recipes and the possibilities of their application.

The Bul-Kathos's Oath set is inextricably tied to builds that revolve around Whirlwind, either using it as a damage mechanic or a utility movement skill. This 2-piece set is somewhat oriented towards speed farming, as it bumps up both Attack and Movement Speed while Whirlwinding, and gives you a massive boon to resource management via passive Fury regeneration. Note that the Movement Speed increase of the Bul-Kathos's Oath set allows you to exceed the natural cap of 25% Movement Speed coming from items.

The Fury regeneration bonus alone allows you to either drop resource management tools (i.e. generator skills, passives like Unforgiving, or the Wind Shear rune of Whirlwind), or to introduce Fury-reliant bonuses to the build (i.e. the passive Berserker Rage, or the damage reduction of Aquila Cuirass).
