Build Requirements

This build has several Legendary Aspects that are required before it will function properly. For the Legendary Aspects you will need the following at a minimum to make the build work at its most basic level. These Aspects are all non-codex, which means you will need to find them on a Legendary Item then imprint them onto specific gear.

Optional Uniques
Required Aspects (Non-codex)

To even begin this build, we recommend you have these Aspects ready for imprinting at a minimum. For the build it become fully functional, we recommend you have all the Legendary Aspects listed further in this guide for the build to work optimally.

Season of Blood

Season 2 Patch Updates

This build has been designed within Season 2 with all mechanics coming from the current patch cycle. Important items to note about Season 2 are:

  • Resistances new stack additively and no longer become less effective with each additional source, while also contributing their full value to Non-physical Damage Reduction. Resistance values on equipment, Elixirs and Paragon have been increased to more easily reach the new 70% cap. Furthermore, Intelligence now gives +0.025% All Resistance per 1 Intelligence instead of 0.05% All Resistance to compensate.
  • Increased Critical Strike / Vulnerable Damage affixes are now additive with other damage increases instead of being multiplicative. This change is a nerf to make Critical Strike Damage and Vulnerable Damage comparable to other dame increase options. All classes are affected by this change.
  • % Total Armor affix has been increased by 160%.

Vampiric Power Tier List

Season 2 introduces Vampiric Powers that provide build-altering bonuses. We start by spending Potent Blood, which is acquired from vampiric enemies, to unlock and upgrade your Vampiric Powers. Make sure your equipped chest armor, pants, gloves, boots and helm contain the appropriate Vampiric Pacts (Ferocity, Divinity and Eternity) that match the activation costs needed to unlock a Vampiric Power.

A Vampiric Curse status effect has been added to complement the new powers: killing an enemy affected by your Vampiric Curses will store their soul. Casting a Defensive skill will unleash your stored souls to attack nearby enemies. You can store up to 8 souls total.

Listed below is the tier list for Vampiric Powers , ranked by importance to this build. Stat values displayed reflect a maximum level 3 Vampiric Power.

Minor Powers:

  • Sanguine Brace (1 Divinity, 1 Eternity): When you kill an enemy, Fortify for 6% of your Base Life. While you have more Fortify than half of your Maximum Life, you gain 8% Critical Strike Chance.
  • Prey on the Weak (2 Ferocity): You deal 16% increased damage to Vulnerable enemies. Enemies are Vulnerable while affected by a Vampiric Curse from your other Vampiric Powers.
  • Ravenous (3 Ferocity): Lucky Hit: Up to a 20% chance to increase your Attack Speed by 40% of your Total Movement Speed for 6 seconds.

Major Powers:

  • Accursed Touch (6 Divinity): Lucky Hit: Up to a 44% chance to inflict Vampiric Curse on enemies. Enemies with the Vampiric Curse have a 15% chance to spread it to other surrounding enemies. Accursed Souls deal 200% increased damage.
  • Metamorphosis (2 Ferocity, 2 Divinity, 2 Eternity): When you Evade you turn into a cloud of bats, becoming Unstoppable for 4 seconds. Enemies along your path take 160% Physical damage and are inflicted with Vampiric Curse.

Weapon Expertise – The Barbarian Specialization

Weapon Expertise is a set of benefits tied to which weapons you use as a Barbarian. To unlock your Expertise, simply hit Level 5 and the tab below will be made available. By using a certain weapon type, you will begin to gain ranks with that weapon as you fight. The ranks are from 0 to 10 and will level up moderately quickly as your character gains experience. Once your expertise hit rank 10, you will be maxed out on the benefit for using that weapon with your skills. As a reminder, to swap your assigned weapon to the skill you are using, go to your Skill selection list (not Skill Tree) and you will see how to switch it. For mouse and keyboard users, you can access this by pressing the middle mouse button. At Level 15, you will unlock the Masters of Battle quest. This quest will be available in the township of ‘Ked Bardu’ from the Forgemaster Gerti. Upon completing this quest, you will unlock the Technique slots as seen below. This will offer you an additional permanent bonus from one of the weapons regardless of whether you have it equipped to a skill or not.

For the Walking Arsenal Build, we use the two-handed axe Technique to raise our damage against Vulnerable Enemies.

Weapon Selection

Barbarians have an unique mechanic in Diablo 4 where you can assign a weapon type to certain skills. This is a critical component for all builds to function properly, and failure to match your weapon to the proper skill may cause the build to perform poorly. For our Walking Arsenal build, we will be assigning the following weapons to our skills:


We recommend using these Legendary nodes and Rare Glyphs to truly take this build into the endgame. Note that each Rare Glyph’s information listed below is for the Level 21 version.

Build Mechanics and Playstyle

The playstyle for this build is designed behind a single major component; weapon swapping. This opens us Critical Strike chances, lowers the cooldown on Iron MaelstromIron Maelstrom and unlocks our Key passive Walking ArsenalWalking Arsenal. To accomplish all of this weapon swap, we assign different weapons to each of our skills. Then we simply cycle our skills as we play normally, following a very simple rotation which we will be using to stay in Berserking.

  1. Lunging StrikeLunging Strike has a chance to push us into Berserking if we hit a Critical Strike.
  2. If UpheavalUpheaval hits 2 enemies or a boss, you will gain Berserking.
  3. Death BlowDeath Blow is our best shot at gaining Berserking as it just needs to hit a single enemy to trigger, and thanks to Weapon Master's AspectWeapon Master’s Aspect, we’ll have two chances to do this. Death BlowDeath Blow will reset its charges if we kill an enemy with it.

So we simply build out a pattern:

  • Lunging StrikeLunging Strike leaps towards and enemy or pack of enemies.
  • Follow up with an UpheavalUpheaval, causing AoE damage to the pack of enemies.
  • Now, we finish off their health with Death BlowDeath Blow – this gains the benefits from our Unique two-handed OverkillOverkill – making the attack have a nice wide arc to the attack so hits are easy to make.

These cycle will be repeated over and over, keeping you in Walking ArsenalWalking Arsenal the entire time and using Rallying CryRallying Cry to keep our Fury up. We also gain the advantage of Overpower strikes with Earthstriker's AspectEarthstriker’s Aspect. Then we can use all of this build up to strike down the entire screen using Iron MaelstromIron Maelstrom. The cooldown timer on our Ultimate is also lowered non-stop by us constantly switching weapons, and we gain massive damage from Berserking and Walking ArsenalWalking Arsenal, making our Ultimate devastating, especially if we hit an Overpowered strike.

Iron Skin

Our entire build is made to amplify our damage and crush everything we fight, but it does leave us open to attacks. For this we have added Iron SkinIron Skin as our shield against Damage. This simple Barrier and heal will keep us out of harms way and carry us through a difficult fight. This is amped up further with the defensive aspect, Aspect of the Iron WarriorAspect of the Iron Warrior, for even more Damage Reduction.

Gear Choice and Stat Priority

As you begin to farm in World Tier 3 and 4, Rare and Legendary item drops will begin to appear with some regularity depending on your luck. We recommend saving the targeted Legendary items that have the needed Legendary aspects listed below. We also recommended to keep multiple copies of the build’s Aspects in your Stash for future upgrades.

As for the Rare items, you will need to inspect each one for targeted affixes for use in each specific slot and do your best to match the recommended rolls. We have listed our targeted affixes in order of importance. Check the chart below and make note of what affixes you are searching for when you see a Rare gear piece drop.

Season 2 Update (1.2.0): Critical Strike Damage and Vulnerable Damage affixes are changed to be additive with other damage increases. All additive damage increases of the same amount are equal in value, as long as their conditions are active.

We have kept the affixes for the Amulet slot if you do not have Banished Lord’s Talisman

Please note that these affixes are the recommended picks for this build, but that is simply our opinion. Other affixes could certainly work instead of the ones listed above, but may not be optimal.

  • Fury Cost Reduction
  • Rank ups to selected Skills
  • Cooldown Reduction – this is mainly for our Iron MaelstromIron Maelstrom.

A final point on acquiring the right Affixes and Legendary Aspects, use your Obols to target farm them. Obols are awarded from many different activities in the game, you will always stockpiling them until you hit your maximum. Instead of just randomly spending them on a random pick, use them to target what you might be missing from this build. It is a great way to target a specific slot of loot and find what you need.

Legendary Aspects

Listed below are all the best-in-slot Aspects found on Legendary items that are important for the Double Swing Barbarian build. Aspects from the Codex of Power can be used if you cannot find the proper Legendary drops, but they have weaker effects.

The endgame itemization goal will be to imprint Aspects with the best values Ancestral Rare items with Item Power above or as close to 800, then upgrade them through the Blacksmith.
