MMOexp-Diablo 4: Permanent Berserking + Infinite Whirlwind Build

 If you're looking for the strongest, tankiest, and fastest speed-farming Barbarian build in Diablo 4 Season 10, look no further-the Shotgun Dust Devils Barbarian is currently the king of efficiency. This setup blends ridiculous tankiness with screen-melting damage, instant mobility, and some of the strongest unique synergies in the game. Whether you're farming Tier 4, blasting Helltides, or zooming through Nightmare dungeons, this build turns your Barbarian into a tornado of destruction that never stops moving.

This guide breaks down every part of the build-skills, Paragon, gear, tempering, runes, playstyle, and even how to convert it into a push-oriented version. By the end, you'll know exactly why players call this build "Omega Tanky" and why it's currently one of the best speed-farming setups in the entire game.

Why Shotgun Dust Devils Is the Best Speed-Farming Build

The core of the build revolves around generating Dust Devils at extremely high frequency, and then stacking multipliers so those Dust Devils "shotgun" enemies up close. Combined with Whirlwind's mobility and Lunging Strike's buffs, the build maintains permanent Berserking, constant movement, and enough damage to one-shot bosses-even while standing still.

A few quick highlights:

 Can clear T4 with only a couple Uniques

 Permanent movement, fury, Berserking uptime

 Near-immortality thanks to massive DR and shouts

 Dust Devils hit twice due to tempering synergy

 Whirlwind is fully free thanks to Beast Cornered

 One-shotting bosses even at low HP

 Can tank almost anything-except the occasional beam

This is speed farming at its finest: simple rotation, constant motion, and zero downtime.

Skill Breakdown

Basic Skill-Lunging Strike

Lunging Strike is a surprisingly important piece of this build. It:

 Procs Belligerence

 Procs Warpath

 Always overpowers thanks to Unstable Power

 Refreshes its cooldown in sync with your buffs

Using it every 4 seconds boosts your damage by over 100% with good masterworks. It's a consistent self-buff, a mobility tool, and a resource generator all in one.

Core Skill-Whirlwind

Whirlwind functions here primarily as a Dust Devil generator, not your main source of damage.

Key notes:

 You do NOT need points in it

 Sabra and Starless Skies grant enough free ranks

 Beast Cornered solves all Fury issues

 The build spams Whirlwind nonstop

This is why the build feels incredibly smooth-Whirlwind is always active, fast, and free.

Shouts-The Build's Backbone

You use all three:

 Rallying Cry-Unstoppable + Fury engine

 Challenging Shout-Big DR and chunkier HP

 War Cry-Berserking uptime and extra damage

Since the build auto-procs so many multipliers through your shouts, pushing them on cooldown is essential.

Ultimate-Wrath of the Berserker

Wrath of the Berserker:

 Converts your damage to fire

 Scales damage massively through Unconstrained

 Boosts movement speed and Fury generation

This build runs 100% uptime thanks to rune synergy-more on that later.

Key Passive-Unconstrained

Still the best universal Barbarian passive for any non-bleed build. More Berserking = more speed, more damage, more tankiness.

Paragon Boards & Glyphs

The Paragon setup mixes additive synergy with multipliers that boost Dust Devils, crit, and Berserking uptime.

Boards Used

1.Starting Board

2.Flawless Technique-makes crit cap trivial

3.Challenger-universal staple

4.Blood Rage-mandatory on all Barb builds

5.Twister-MASSIVE Dust Devil additive + multipliers

6.Carnage-attack speed + damage

7.Wrath or Exploit-for speed farming, Exploit is usually better

8.Force of Nature-creates more Dust Devils via Earthquakes

Important Glyphs

 Twister-by far the most powerful for Dust Devils

 Undaunted-additive + DR

 Wrath OR Exploit-depending on preference and content

Even though the build lacks many multiplier glyphs, it stacks so much additive + multipliers from gear that Paragon functions as a damage amplifier, not a dependency.

Best Gear, Aspects & Masterworking

Mandatory Mythics

1. Starless Skies

The single strongest Barbarian unique in Season 10.

 Cuts your Fury costs drastically
