Gear, Gems, Elixirs, and Stats

The Season of Loot Reborn brings us an incredible shift in how gear and itemization are done. It is a major and will affect the game beyond Season 4’s confines. For further details, make sure to read our Tempering and Masterworking section below.

Legendary Aspects

Below you will find all of the best-in-slot Aspects found on Legendary items that are important for this build. Remember that with Patch 1.4.0 all Legendary powers can be added into your Codex once you salvage or extract the item. You can still find some aspects through dungeons as you could in previous seasons but now you have the option to upgrade these affixes if you find a higher roll of that affix. Let us go over what aspects you will need.

For your jewelry, it may be necessary to change the Royal DiamondRoyal Diamond for another gem for a specific type such as Royal SapphireRoyal Sapphire to ensure all of your resistances are capped at 70%

Which Elixirs Should You Use?

Visit the Alchemist in any main town to craft helpful Elixirs that increase stats, and experience gain for 30 minutes. Make sure to forage plants and pick up the necessary crafting materials during your adventures; they randomly spawn around the world. Use an Elixir providing any Resistance you need most, or the Elixir of Destruction which increases your Overpower damage. Craft the highest Elixir of Destruction you can

Return to the Alchemist again when you reach Level 20, 30, 45, 60, 70, 80 and 90, to upgrade your potion. The extra healing is essential to survival.

Gear Choice and Stat Priority

With all of these new systems in mind, let us dive into what stats we want on gear, what tempers we would like, and what stat we would prefer to be pumped either through a Greater Affix or through Masterworking. Affixes that are bolded in yellow are the most important targets for Masterworking upgrades. The tempering manuals you need to apply the affixes will be linked next to each affix we want.

  • The GrandfatherThe Grandfather – An extremely powerful 2-Handed Slashing Weapon. Edgemaster’s AspectEdgemaster’s Aspect is dropped entirely and replace with Aspect of Encroaching WrathAspect of Encroaching Wrath if you’re fortunate enough to loot one of these amazing swords.

Season 4: Loot Reborn

Unlike past seasons there is no overarching theme for season 4 as Blizzard is focused on the absolutely massive loot overhaul which is sure to change the game in big ways. There will also be a reputation to be gained with the new Ironwolves during Helltides and this faction grants several tempering manuals and even a resplendent spark! Below are the changes relevant to this build.

  • Barbarian’s innate 10% Damage Reduction has been removed
  • Banished Lord's TalismanBanished Lord’s Talisman ‘s resource required to guarantee an Overpower reduced to 275 from 300. Damage bonus reduced from 80-120% to 20-60%

Advanced Information

Below, you will find every additional piece of information you need to know for a more in-depth look at this build.

Mechanics and Playstyle

This build is a lot more involved than it might first appear. We want to benefit from the build’s namesake passive Walking ArsenalWalking Arsenal as much as possible. This requires us to swap weapons constantly, something that should come fairly easily. We’ll use Lunging StrikeLunging Strike through our Dual Wield Weapons to proc this, use our 2-Handed Mace for UpheavalUpheaval and lastly use our 2-Handed Slashing Weapon for Death BlowDeath Blow. Our ultimate skill of choice, Iron MaelstromIron Maelstrom should have an incredibly high uptime thanks to the new tempering system and its associated affixes which will provide us with a high damage ultimate that also activates our key passive for us by using all weapon types.

We will also use Earthstriker's AspectEarthstriker’s Aspect for even more damage. Though nerfed in Patch 1.4.0 this still retains a solid amount of power for this build. Be sure to snag Weapon Master's AspectWeapon Master’s Aspect to get a second charge on Death BlowDeath Blow to ensure we’ll always have it available. Once you have a solid OverkillOverkill we’ll want to use Death BlowDeath Blow more frequently due to the increased power this unique provides, especially on bosses and single target Elites. We use our LeapLeap for mobility and to proc Aggressive ResistanceAggressive Resistance for survival.

This build plays very differently from more traditional Barbarian builds as it forgoes the triple shout setup and only opts to use Rallying CryRallying Cry for some faster move speed and resource gen to help cast more Upheavals and keep our arsenal bonuses going. This may appeal more to some players who have grown tired of the three shout meta.

Tempering and Masterworking

The Season 4 update (Patch 1.4.0) introduces a rework for itemization. Tempering and Masterworking bring the biggest change to itemization since the release of Diablo 4, so make sure you understand the new systems explained in this section.

The amount of affixes on items has been changed to reflect its rarity: Normal Items have no affixes, Magic Items have 1 affix, Rare Items have 2 affixes, Legendary Items have 3 affixes, and Unique Items have 4 affixes. Upgrading a Rare Item to a Legendary Item by imprinting a Legendary Aspect from the Codex of Power will not add a third affix. Therefore, Legendary Items are superior to lower rarity items for a min-maxed character.

Greater Affixes are a newly added mechanic that increases the value of an affix by 50%. Ancestral Legendary Items and Unique Items can now drop with up to 4 Greater Affixes! Search for items with your preferred Greater Affixes to upgrade with Tempering and Masterworking.

Tempering and Masterworking is an important system, even mandatory in the endgame, for character progression. You are able to add 2 additional affixes on any Rare Item or Legendary Item, exclusive to the Tempering System. An Ancestral Legendary Item can have up to 5 total affixes! Unfortunately, Unique Items cannot be tempered to add affixes.

Masterworking uses new crafting materials found in The Pit to further enhance the stats of an item. These upgrades can be applied on an Ancestral Legendary Item that has its Tempering Slots filled out. Unique Items can be upgraded with Masterworking right away, as tempering does not apply to them. Each item has 12 upgrade slots. On upgrade Ranks 4, 8, and 12, a random affix is increased in value by 25%. Every other upgrade Rank applies a 5% increase to all affixes on an item. Attempt to apply the bonus 25% upgrade to your preferred affix multiple times by resetting the Masterworking Ranks to repeat the process.

Obol Gambling

A final point on acquiring gear in Season 4 and beyond is using your Obols to target farm specific slots instead of randomly spending them on random drops. Similar to Kadala in Diablo 3, you can use Obol vendors in town to try and get what you’re missing. With Patch 1.4.0 when a level 100 Character spends Obols, all gear from that vendor will be 925 item power, the highest in the game, allowing you to fill out gear with the affixes or Legendary Aspects you need.
