The Worldroamer Barb is really a hybrid variant from the Barbarian that employs all 3 primary offensive abilities (Whirlwind for damage, Frenzy for move speed and sustain with lifetap, and Beserk for physical immunes). Additionally, Find Item should receive a minimum of a single point, but additionally be min/maxed based on your preferred harm to MF% ratio. Unlike the Pitzerker variant, the Worldroamer works well in every area, especially as a magic finder, as well as less micromanagement compared to Pitzerker. You will have more autonomy to farm every area including terror zones, though may struggle with higher problems with clear speed.
There may be the standard Stat distribution, however, a far more detailed discussion is available below where additional considerations may mean a complete vita barb is suboptimal. Buying d2 resurrected items and diablo 4 items can help boost your gear in D2R Ladder, which benefits physical damage dealers and specs that benefit from scaling.
