Fierce Brawler

Fierce Brawler is a passive talent in the Berserker (Orange) tree.

In-game
This talent works similarly to the Diablo III Weapons Master passive: it simply adds a bonus to the Barbarian depending on which weapons they currently are using. It only applies for the weapons currently used for the attack, not for the entire Arsenal, so it's not possible to gain both effects at once and likewise not possible to apply an effect to a skill with the wrong weapons set.
