Frenzy WW or Beerserk?
I want to farm travi + hork but its boring so sometimes i want to farm tz / bosses
What is the fastest build to do that? And why

Ww for tz and trav
Berzerk if you wanna snipe elites
Id recommend throw over frenzy

Berserk for me.

Maybe I am bias, but I used berserk for whole game ... that is LoD though, not D2:r, however I would think it is still pliable.

Gotta go berserk if you’re horking. Shout away the trash mobs and only kill champs and elites. It’s the most efficient magic find method in the game

Howl ... Shout adds Defense.

Best build is a mix of all 3 skills imo.
My barbs setup for chaos runs with max frenzy max ww and 1 point zerk and with fort not enigma.
Chaos is the best area for a barb other than trav. Ez to switch gear for both.
If u want just kill elites and tele use zerk. But you won't find as good drops from just elites as you will in chaos...
