What does the Horadric Cube do in Diablo IV?

In the Lord of Hatred expansion, the Horadric Cube lets players transmute random affixes onto any item rarity, strip unwanted affixes, upgrade rarity (common all the way up to unique of the same slot), fuse three identical uniques into a new unique, and transform a unique into a charm version. It is unlocked through the Lord of Hatred campaign and lives in the hub city of Temis.

Where is the Horadric Cube in Diablo IV?

The Horadric Cube is located in Temis, the marble hub city of Skovos, unlocked during the Lord of Hatred campaign. Alongside it in the same plaza are the War Plans interface, all four artisans, the Purveyor of Curiosities, and entrances to The Pit and Echoing Hatred.

How is the D4 Horadric Cube different from Diablo III's Kanai's Cube?

Kanai's Cube in D3 extracted legendary powers into separate passive slots. The D4 Horadric Cube modifies items themselves — upgrading their rarity, editing their affixes, or fusing three duplicate uniques into a new one. It brings low-tier drops back into the endgame loot pool because any item can now roll greater affixes and be cubed up to legendary or unique.

What materials does the Horadric Cube need?

Blizzard has confirmed that recipes require specific rare materials from salvage and drops, but the exact material lists are intentionally undisclosed — Blizzard stated some recipes and outcomes are being kept secret until players discover them after launch.

Can the Horadric Cube craft Mythic Uniques?

Blizzard has not confirmed whether Mythic Uniques can be crafted through the Cube — this is explicitly undisclosed. Expect clarification on launch day or via the April 23 developer livestream.

Horadric Cube — Diablo IV Guide

By the DiabloBytes team · Updated April 2026 · Lord of Hatred

The Horadric Cube returns in Lord of Hatred — a crafting artifact that reshapes Diablo IV's endgame loot loop. Unlike Diablo III's Kanai's Cube, which extracted legendary powers into separate passive slots, D4's Cube modifies the items themselves: transmuting affixes, elevating rarity, fusing duplicate uniques, and converting gear into charms. Every drop, even a common, is now a potential endgame piece.

Where to Find the Cube

The Horadric Cube is housed in Temis, the marble hub city of Skovos. You unlock access during the Lord of Hatred campaign. It sits in the central plaza alongside the War Plans interface, all four artisans, the Purveyor of Curiosities, and entrances to The Pit and Echoing Hatred — Blizzard's direct response to the scattered-vendor complaints of base Diablo IV.

Confirmed Recipe Categories

Seven confirmed recipe categories. Exact material costs are intentionally hidden until launch.

Add Affix Transmute random affixes onto any Common, Magic, Rare, or Legendary item. Targeted affix crafting for BiS pieces.

Remove Affix Strip an unwanted affix off existing gear. Clears a slot for re-rolling or transmutation.

Elevate Rarity Upgrade Common → Magic → Rare → Legendary → Unique of the same slot. A junk-tier item can become BiS if cubed up with enough materials.

3-to-1 Unique Fusion Combine three identical Uniques into a new Unique of that type. Rescues bad-roll unique drops and enables re-rolling the affix RNG.

3-to-1 Slot Transmute Combine three items of the same slot (e.g., three belts) into one new item of that slot. Extends to Talismans, the new charm-equivalent system.

Unique-to-Charm Transform a Unique into a charm version of itself. Original is consumed. Functions like a secondary equip slot for Unique effects.

Transfiguration Final crafting step. Gambles bonus effects onto an item (Blizzard described it as mirroring Season 11’s Sanctification). Locks the item from further modification. Won't reach the raw power levels of S11 sanctified gear.

Also confirmed but with fewer details published: combining runes, combining consumables, and combining dungeon keys. Recipe formulas remain undisclosed.

How the D4 Cube Differs

System	What It Did
D2 Horadric Cube	Simple recipes — socket an item, upgrade uniques/sets, combine runes into runewords, transmute gems. Limited scope.
D3 Kanai’s Cube	Extract legendary powers into 3 passive slots (Weapon / Armor / Jewelry). Did not modify items themselves.
D4 Horadric Cube	Modifies the items. Transmutes affixes, upgrades rarity, fuses 3 identical uniques into a new one, converts uniques to charms, transfigurates for gambled bonuses.

The critical shift: low-tier drops matter again. In base Diablo IV, commons, magics, and rares were trash once you hit endgame. With the Cube, any item can roll greater affixes (previously legendary-exclusive) and be elevated to legendary or unique. A perfect-roll common belt is now a potential BiS.

Strategic Use Cases

◆
Fix a bad-roll BiS unique Stockpile duplicates of your build’s critical unique. Fuse three into a new roll. Repeat until the affixes land.
◆
Rescue low-tier greater affix gear A common or rare with a greater affix you care about — elevate rarity through the Cube to legendary or unique.
◆
Double up on unique effects Convert a duplicate unique into a charm. Effect now applies from both the equipped unique and the charm slot simultaneously.
◆
Transfigurate for a build-defining bonus Late endgame: accept the lock-in, gamble a transfigure for a bonus that pushes your build over the edge.
◆
Targeted affix crafting Strip an unwanted affix, transmute a new random one. Costs materials but gives control over otherwise-RNG-locked items.
◆
Salvage-to-craft loop Every drop is fuel. Even commons feed elevation chains. Salvage nothing until the Cube tells you to.

What's Still Hidden

Blizzard has intentionally kept several things secret until launch. Do not trust pre-launch claims for these:

? Whether Mythic Uniques can be crafted through the Cube
? Exact material names, drop sources, and drop rates
? Full rune-combining formulas
? Whether new Talisman sets have exclusive Cube recipes
? Transfiguration cost/success rates
? Weekly/daily Cube usage limits if any

Launch Day Strategy

1
Push campaign to unlock the Cube The Cube is gated behind a specific LoH campaign beat. Rush there before grinding — it is Day-1 priority.
2
Do not salvage in the early days Every drop has cube potential. Hoard everything in a dedicated stash tab until you learn the recipes.
3
Test cheap recipes first Before committing to a big transfigure, test add-affix and remove-affix on throwaway items to learn the materials and reroll behavior.
4
Save uniques in sets of three Don’t discard duplicate uniques. The fusion recipe requires three of the same, so stockpile until you have a full set.
5
Hold transfigurations for confirmed BiS Transfigure locks the item from further modification. Only use it when you’re sure the item is your endgame piece.
