Equip the Seneschal with two Governing Stones to activate their abilities, and then link them to three Tuning Stones each to augment the abilities.

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:

• Lunging Strike – Dual wield
• Upheaval – Bludgeoning
• Death Blow – Slashing
• Iron Maelstrom – Bludgeoning

Paragon

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.

Blood Rage	– Killing a Bleeding enemy has 10% chance to grant Berserking for 5 seconds. Your Damage is increased by x25% of your Damage while Berserking bonus.

Let’s break down each of these beneficial nodes and where our Paragon Points are positioned in each of the paragon boards we use. This part of the build is presented in order of importance. If you do not have enough Paragon Points to use in your Paragon Tree, just slowly work towards each step.

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 Maelstrom and unlocks our Key passive Walking 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 Strike has a chance to push us into Berserking if we hit a Critical Strike.
2. If Upheaval hits 2 enemies or a boss, you will gain Berserking.
3. Death 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 Aspect, we’ll have two chances to do this. Death Blow will reset its charges if we kill an enemy with it.

So we simply build out a pattern:

• Lunging Strike leaps towards and enemy or pack of enemies.
• Follow up with an Upheaval, causing AoE damage to the pack of enemies.
• Now, we finish off their health with Death Blow – this gains the benefits from our Unique two-handed Overkill – 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 Arsenal the entire time and using Rallying Cry to keep our Fury up. We also gain the advantage of Overpower strikes with Earthstriker’s Aspect. Then we can use all of this build up to strike down the entire screen using Iron 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 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 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 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.

Gear Slot	Targeted Affixes
Helm	1. Cooldown Reduction 2. Ranks of Death Blow 3. Strength 4. Needed Resistances
Chest	1. Damage Reduction while Fortified  2. Damage Reduction from Close Enemies  3. Damage Reduction 4. Maximum Life 5. Ranks to Rallying Cry
Gloves	1. Critical Strike Chance 2. Ranks Of Upheaval 3. Strength 4. Attack Speed 5. Lucky Strike
Pants	1. Damage Reduction while Fortified 2. Damage Reduction while Injured 3. Damage Reduction from Close Enemies 4. Maximum Life 5. Damage Reduction
Boots	1. Movement Speed 2. Strength 3. Fury Cost Reduction 4. Needed Resistances
Amulet	1. Cooldown Reduction 2. Fury Cost Reduction 3. Movement Speed 4. Ranks of Brute Force 5. Damage Reduction
Rings	1. Critical Strike Chance 2. Overpower Damage 3. Critical Strike Damage 4. Maximum Life
Weapons	1. Strength 2. Overpowered Damage 3. Critical Strike Damage 4. All Stats 5. Damage to Close Enemies

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 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. Extract Aspects from lower level Legendary items and imprint them onto better Rare items with preferred stats. 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. Each aspect is listed with its matching gear slot. Do your best to keep each aspect in the slot it was posted with.
