um, 1 grief is bis most of the time not 2. 2 is good for the standard pvm ww build. there 100s of other ways to build viable pvm barbs. grief/beast probably does more damage than 2 griefs if you are using an enigma. grief/death will be better vs bosses. grief/asurewrath will be better vs undead and for QoL. grief/ss is better of berserk, tanking, taking naps in cow games, for bladethrow/ww hybrid. big damage 2 handers are better for berserk too. hotos are better for singers........

nothing wrong with grief/death.

Just be sure to make it into an eth elite base, otherwise youre going to regret it later.

136 str req of a colossus sword isnt high for a barb.Barbarian items gives high str.
Zwihander have to low base dmg

Any PvM Barb should have ~350-400 Str, so what is a problem ?

Even a azure wrath is prob better than death phase blade
