The Worldroamer Barb is a hybrid variant of 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.

As you won't necessarily require more life points given your strong resistances, life leech, life tap, and good general survivability. You can add additional strength for damage, or dexterity for attack rating while you see fit.

Playstyle and Notes:

The play style for that Worldroamer is fun, high-speed, and varied. You will be somewhat tanky, particularly when your fade is proc’d from Last Wish. You will have high damage and attack speed, and improve your speed then you can teleport once Frenzy is stacked. Your main damage source is whirlwind, however, you should be weaving Frenzy attacks during attacks, to make sure movement and IAS stacks are kept up between mobs. Additionally, make sure to switch to Beserk for Stone Skinned champions, or high physical immune act bosses like Baal. You should have good life leech your items and mana leech in the ring slot (hopefully). However, should you require extra sustain, change to Frenzy before you lifetap. Remember to use Find Item whenever you kill champion monsters.

Standard, Pitzerker Variant (Currently Strongest D2R MF Build):

I will even briefly cover the pitzerker variant within this guide because the Worldroamer can be simply tweaked to become Pritzker with some gear changes (and easily attainable tokens or stat reset quest). By taking advantage of the Find item ability open to the Berserker Barbarian, you can double monster drops and fast-track your Magic Finding (you can stack up to 1000% MF). Zerk Barbarian when fully equipped may be the best specialized Magic Finding build hanging around, designed to excel and farm in specific high ilvl areas where you can find the rarest drops and many more expensive loots with no struggle of slow kill speed.

Stats:

The Zerk barb’s specialized expertise means that you simply need enough Vitality to make sure you don’t die inside the specific areas you're farming. This also releases extra points either to strength (more damage) or dexterity (more attack rating). I prefer strength as Berserk already supplies a large AR boost.

The above skill build optimizes your find item ability, comprising diminishing returns around 70-75%. Find potion provides a flat non-diminishing 1% for your find item ability and maybe the better capability to max first out of the two.

The remainder of your abilities ought to be towards maximizing your Berserk damage, and Battle Orders. You may consider opting directly into maximizing Berserk damage first, should you not require the survivability of Battle Orders.

Charm 1: Barbarian Hellfire Torch

Charm 2: Annihilus

Charm 4: 40% Magic Find Gheed’s Fortune

Rest of Charms: Small Charms with 7% Magic Find (Resistances or Max damage / AR desirable secondary mod)

While it might take one item (Arreats Face providing 30% FHR) to attain a 3-frame difference inside your FHR, it's unnecessary because of the un-incorruptibility of Berserk, and to go for Shako to have an even higher MF%. FCR is essential to max your speed during MF runs. It is essential to teleport quickly while you look for boss minions to kill and force double drops from.

Merc Gear

Weapon: Ethereal Reaper’s Toll

Body Armor: Treachery 

Helm: Ethereal Andariel’s Visage with Ral Rune

Conclusion

The Worldroamer is a very strong magic-finding “generalist” Barbarian who should excel at solo farming every area and traversing the whole D2R landscape. The playstyle should suit the ones that prefer to explore more compared to optimized farming areas (when compared to “specialized” MF pitzerker which serves the alternative purpose). Given the gear overlap, you can easily transition from one to the other with minimal additional gear investment, to consider gearing for both on a single character.
