Diablo 4 Barbarian BuildDragon's Breath Upheaval

Burn Baby Burn!

This build focuses on scaling burning damage through Hellhammer & The Ugly Bastard, firstly the Hellhammer will cause your Upheavals to set the ground on fire applying a burn to any enemy that comes into contact with it. The damage the burn deals scales on your strength, so you'll see in the gear the emphasis on master working our core stat.

The Ugly Bastard converts all physical damage into fire while we are berserking which is nice and in keeping with the theme but more importantly it increases all fire damage we do by up to 80%x. Thanks to Violent Upheaval we have permanent berserking so this bonus has as good as 100% uptime.

Once you get your hands on these two uniques you're ready to start causing some serious damage with fire! It's important to remember that Burn damage cannot crit and that is why you see vulnerable damage being stacked in it's place with this build.

Bash

We're using bash to accomplish a couple of things, firstly it generates fury which helps feed our Upheaval, secondly by using Combat Bash (4 critical strikes = next core skill Overpowers) in conjunction with the temper Bash Now Cleaves we're now able to more or less guarantee an overpower every time we Mighty Throw in an AoE context.

Doing this also allows us to tap into two of the new passives, Warpath & Belligerent both powerful damage multipliers that can be maintained 100% of the time using this tech, so as I like to often say "easy money".

Yen's Blessing & Shouts

We're finally seeing a shift in the three shout meta with this new setup with Yen's Blessing the way this unique works is that every 8 seconds it will cast any non-Ultimate/mobility skill that is on cooldown. By setting our build up the way we have this guarantee that it will always cast Rallying Cry providing you keep it on cooldown.

Then by combining this effect with Booming Voice which increases the duration of a shout to 7.4 seconds, we're able to maintain a near 100% uptime on our chosen shout and all the associated benefits with it.

This means a near permeant state of Unstoppable increased resource regen & allows us to tap into downstream benefits such as Tibualts Will providing further resource bumps, 20x damage and a healthy amount of damage reduction. All of this and the affixes on the boots themselves are also incredibly useful.
