Diablo IV Horadric Cube Guide: How to Craft the Best Gear

Diablo IV’s latest expansion, Lord of Hatred, dropped this week and it’s added finally added the Horadric Cube to the game. Where the Occultist is about rolling the dice and hoping, the Cube is about targeting exactly what you want and building toward it deliberately. Understanding the Cube removes a lot of frustration from RNG drops, by giving you a true crafting option. And it makes every drop, regardless of rarity, potentially important as a base to build upon.

Once that clicks, the whole endgame gear loop changes. Here’s everything you need to know about the Horadric Cube in Diablo IV.

The Materials

Before you touch the Cube, you need to understand the materials that fuel it, because they’re not all equal and some are significantly harder to get than others.

Common Dusts and Prisms are the everyday currency. These come from War Plans, Infernal Hordes, breaking down Talismans, killing elite monsters, etc. You’ll accumulate these naturally just by playing.

Tuning Prisms are the real game-changers. These are what separate the Cube from every other crafting option in the game. They let you force a specific category of stat when you’re adding an affix, which I’ll get into in a moment.

Attuned Primordial Dust is the top-tier material. It only drops in Torment 10 and above, and it’s rare. You need it for the highest-level operations like randomizing Unique Powers. Don’t burn it carelessly.

Enhanced Primordial Dust is used to upgrade Common items into Uniques, which opens up a crafting path I’ll cover below.

Boss Trophies are no longer just passive drops you get from killing world bosses or Helltide. They’re actual crafting materials now, and you earn them by opening chests with Layer Keys or Greater Layer Keys, nightmare dungeons, world bosses, and Tree of Whispers. Save them.

Affix Manipulation: The Key to Crafting Your God Roll

This is where most of your time in the Cube will be spent, and it’s where the Cube genuinely outclasses anything else in the game when used correctly.

Adding an Affix

The basic version just throws a random affix onto your item. That’s fine for casual use, but the Cube’s real power comes from pairing an Add Affix with a Tuning Prism to force the roll into a specific category. The categories are:

• Skill/Core (ability bonuses)
• Resistance (fire, poison, specific elements)
• Offensive (damage boosters)
• Mobility/Utility (movement speed, cooldowns)
• Defensive (life, armor)
• Resource (class resource, resource reduction)

The strategy that experienced players are using is starting with a white “Common Ancestral” base item. These have zero stats but high item power. You then use targeted Add Affix operations with the appropriate Tuning Prisms to manually build the exact stat spread you want, three or four affixes, chosen by you. That’s not something the Occultist can do.

To illustrate, I had a 2 Greater Affix Amulet drop when I was using a standard legendary one that was 793 power level.

 

So I add it to the Cube, and under recipes choose Add Affix. It will cost 1 Coarse Primordial Dust and 5 Primordial Dust. I wanted Movement Speed added to it, so I tossed in a Pragmatic Tuning Prism.

And that, when transmuted, produced this rare ring:

And it gave me Lucky Hit Chance, which I didn’t want. So I switch the recipe to Remove Affix and keep the Pragmatic Tuning Prism inserted. Removing an affix cost 1 Refined Primordial Dust and 15 Raw Primordia Dust, so much more expensive to tear down an item than it is to build it up.

I didn’t grab a screenshot of it, but transmuting that dropped it back down to the original 2GA magic item. I switched it back to Add Affix, transmuted it again, and got my Movement Speed on the second attempt.

So then it was time to add a fourth affix, and this time I wanted Critical Strike Chance.

So I switched out the Pragmatic Tuning Prism for the Aggressive Tuning Prism, which targets Offensive affixes.

And that gave me Critical Strike Damage, which isn’t bad but wasn’t what I wanted. So I switched back to Remove Affix as you can see above.

Removing an Affix

If you Add an affix and it lands on something you don’t want, you don’t have to scrap the whole item. Remove Affix lets you strip a specific category out and try again. This is what makes the build-from-scratch approach viable instead of frustrating.

But, if you have two affixes from the same category, well you lose that control. In the image above you can see I have 46% Critical Strike Damage Multiplier (Offensive) and a GA of 30% Physical Damage Multiplier (also Offensive).

I luckily I don’t care about the Physical Damage or its greater affix status (which was so great).

When I removed an offensive affix, it took away my Physical Damage GA, as you can see above. And I did add affix again, and got Critical Strike Chance.

Chaotic Reroll

Your item needs exactly four affixes for this one. What it does is swap one random affix for something from a completely different category. If your item ended up stacked with defensive stats when you wanted more offense, this is how you break that logjam. It’s less precise than Focused Reroll, but sometimes you just need to shake the category spread loose.

Focused Reroll

This one stays within a category but changes the specific stat. The example that illustrates it best: you have Healing Received on an item, and you’d rather have Cooldown Reduction. Both are Utility stats. Focused Reroll cycles within that pool until you land on what you want. For fishing a specific stat out of a known category, this is more reliable than anything the Occultist offers.

Upgrade to Legendary

This recipe, which is under Item Transmutation, allows you to upgrade a Rare item to a Legendary item. It cost 1 Pure Primordial Dust and 10 Raw Primordial Dust.

So I took my amulet and upgraded it to the legendary:

From there I took it to the Occulist, and enchanted it to specifically roll off Critical Strike Damage. I was hoping for Maximum life, but after a few rerolls, settled for Life on Hit.

If you’re wondering why I didn’t remove affix from the Cube, it’s because I didn’t want to rist my Critical Strike Chance being removed even though it was a low roll.

I then imprinted the Demonic Aspect on it, took it to the Jeweler and added a socket. Tossed in a Royal Diamond, and then went to the Blacksmith to Temper more Movement Speed on it. Once that I was done, I fully masterworked it. And this was the result:

---

Transfiguration: The Point of No Return

Transfiguration is the final step in the Cube’s crafting chain, and you need to treat it that way. Once you transfigure an item, it gets tagged as Unmodifiable. No more affix changes. No adding sockets. No masterworking. Whatever it is when you transfigure it is what it stays. At least that’s the most likely outcome. There is the possibility that the item won’t get hit with that, which would allow you to continue to modify it even after Transfiguration.

So the order of operations matters: build your affixes first, do your tempering and masterworking and socket work, then transfigure last.

What does transfiguration actually give you? A powerful random bonus. It can land on Greater Affixes, Legendary Affixes, or significant stat boosts including item quality increases. The outcome is random, which is why the timing of when you commit matters.

So I took my item back to the Cube and selected the Transfigure Item recipe. This cost 1 Volatile Primordial Dust.

And after transmuting it, this was my final product of fully upgraded 1GA Legendary Ancestral Amulet that started life as a 2GA Ancestral Magic Amulet:

It’s not exactly what I wanted, but it was a pretty good upgrade over what I had. I’m relatively happy with it. I know someone is going to see it, and see “Craft the Best Gear” in the title and say “well that’s not the best gear,” and no it isn’t. But that’s how the process works.

Just make sure you always have your item fully upgraded, tempered, whatever you wanted done to it before you transfigure it because more than likely after you do it you won’t be able to modify it again.

If you want to take some of the variance out, you can use a Tuning Prism to remove the highest-risk outcomes from the transfiguration pool. You won’t hit the ceiling, but you’ll get a guaranteed meaningful upgrade without rolling for the moon. The item still goes Unmodifiable either way, so decide what you’re comfortable with before you pull that trigger.

The Amulet Exception

There’s a special Tuning Prism specifically for Amulets that lets you add a second Legendary Aspect and have it stay modifiable. You can run dual Legendary imprints on an Amulet, which is a combination that doesn’t exist anywhere else in the game. If you’re playing a build that leans heavily on specific aspects, this is worth knowing. The Turning Prism for this is called the Kullean Tuning Prism, and it’s a unique one. So not easy to come by, but if you hit Torment IX they will drop more frequently.

Transmutation Recipes

The Cube also handles 3-to-1 conversion recipes, and a few of them are worth using deliberately rather than just as a cleanup mechanic.

The basic recipe takes three of the same rare item type and produces one new random item of that type. Standard stuff. The more useful applications are:

Unique Recycling: Three copies of the same Unique produces a new roll of that Unique. If you’ve got three of the same item sitting in your stash at mediocre rolls, this is how you fish for a better version. Stop vendoring duplicate Uniques before you check if you have enough to recycle.

Unique Charms: One Unique piece of equipment combined with three Unique Charms gives you a new random Unique Charm. Worth keeping in mind if you’re specifically hunting for charm upgrades. It cost 1 Ancestral Unique Item, 3x any Unique Carms, 1 Enhanced Primordial Dust, 50 Raw Primordial Dust, and 100 Infused Horadric Resin to craft a Unique Charm. So it’s very expensive. I personally wouldn’t even bother with this one, I don’t think it’s worth the cost.

Upgrade to Unique: This one is very useful. If you a Common item (white) you can stick it in the cube and for the high cost of 1 Enhanced Primordial Dust and 10 Raw Primordial Dust turn that white item into a unique. It’s how I got my Litany of Stable, by upgrading a white dagger to unique. And yes, it can take a plain white item and roll it as an Ancestral item with greater affixes, it’s how mine came out:

Set Charm Rerolling

This one applies specifically to set items, and if you’re running something like the Harash’s Shadow set, pay attention.

You can reroll a set charm into a different piece of the same set. The goal is fishing for Ancestral Set Charms, which are rare enough that you should expect to do a lot of rerolling before you see one. The payoff is that Ancestral Set Charms can roll with Greater Affixes, and if you’re trying to stack a specific bonus (like pushing skill levels toward the cap), getting that roll on every piece of the set is a realistic long-term target, just not a fast one.

It cost 1 Set Charm, 25 Raw Primordial Dust and 50 Infused Horadric Resin to reroll a Set Charm, but it’s a relatively easy way to complete a set by rerolling your dupes.

Amalgamation and Rune Crafting

Amalgamation uses five Boss Trophies from the same source to generate a random Unique from that boss’s specific loot pool. Beast in the Ice trophies pull from Beast in the Ice’s pool, Lord Zir from his, and so on. This has a chance to produce Ancestral Uniques, which makes it worth holding onto trophies from bosses whose loot table you actually want to hit.

Rune Crafting lets you target specific Ritual Runes rather than hoping they drop. The recipe is one specific rune you’re targeting plus five rare runes plus five legendary runes. If you’re building around a specific rune interaction, this is how you stop leaving it to chance.

The Build Order You Should Be Following

To get the most out of the Cube, the sequence matters:

1. Find a white Common Ancestral base with high item power
2. Use targeted Add Affix operations with Tuning Prisms to build your stat spread
3. Strip and redo any affixes that didn’t land where you wanted
4. Do your tempering, masterworking, and socket work
5. Transfigure last

Deviating from this order, particularly transfiguring before masterworking or adding sockets, wastes the item because it locks you out of those options. The Cube rewards patience and planning. Treat it like a crafting system where the process matters as much as the outcome, and you’ll get significantly better gear than you would by treating it like a slot machine.

The Horadric Cube is one of the best additions to Diablo IV to date. I always loved it in Diablo III, it’s great to have a version of it here. It gives you more control, without making things absurdly easy and fast. It’s a great addition. When used in conjunction with the Occultist and Blacksmith, and Jeweler, it’s how you can take a common or magic item and build it to your personal god roll.
