How to Make Mythic Uniques: Horadric Cube Crafting Guide

Upgrade Direct Item to Mythic in the Horadric Cube now keeps every affix and modification. This guide covers that 1:1 recipe, the one-item Crafted tag limit, all three crafting routes including the Jeweler and the Blacksmith, and direct Mythic drops from Lair Bosses, verified against patch 3.2.1.

BEFORE YOU CRAFT

In Season 15 (patch 3.2.1), Upgrade Direct Item to Mythic in the Horadric Cube is a 1:1 transfer. Feed it an item with the affixes, Tempering and Masterworking you want and you get the Mythic version of that same item with all affixes and modifications retained, with no random factors. In exchange it carries a Crafted tag, and only one Crafted tag item can be equipped at a time. The recipe cannot be used on an Unmodifiable item, so do not Transfigure a candidate.

Four Rules of Mythic Uniques

4

Mythic Is an Item Quality

All Uniques can be Mythic quality: not only the small legacy set, but ordinary Uniques can drop or be crafted as Mythic. In 3.2.1 Iconic Mythics remain Mythic-quality only; the Unique versions of Iconic Mythics tried in the 3.2.0 PTR did not ship.

Item QualityUnique ItemMythic Unique

Always Ancestral

Mythic Uniques are always Ancestral. Even when the eligible Cube input is not Ancestral, the resulting Mythic is Ancestral quality.

Mythic UniqueUnique Item

Unique Power Is Increased by 30%

Mythic quality increases the item's Unique Power by 30%, while its other affix values roll at their maximum. The live item model gives all Uniques two guaranteed affixes on drop.

Only One Crafted Tag Item

Mythics made with the Cube recipe Upgrade Direct Item to Mythic carry a Crafted tag, and only one Crafted tag item can be equipped at a time. Mythics from the Jeweler’s Rune Crafting or the Blacksmith’s Mythic Unique cache carry no tag, so combining crafted and dropped items still lets you equip several Mythics.

Four Ways to Obtain Mythics

Random Drop Sources

In both the Seasonal and Eternal realms, Unique drops have a low chance to come up Mythic. Patch 3.2.1 increased the chance for Mythic Uniques to drop from random sources, and made all Unique items available to drop from level 1 in any difficulty. Blizzard does not publish the rates.

Diablo IVUnique ItemMythic Unique

Lair Bosses and Belial

From 3.2.1, Mythic Uniques dropped by Initiate and Greater Lair Bosses, and those selected from Belial’s Hoard, are limited to that boss’s own Unique item pool. Lair Bosses also drop generic random loot, so a small chance of Mythics outside the pool remains. Greater Lair Boss rates went up slightly, Initiate rates were raised to match Greater, and Belial’s rate also went up slightly.

Guaranteed Drop From Echo of Mephisto

Patch 3.2.1 raised the overall loot quality of the Echo of Mephisto and added a guaranteed Mythic drop. You cannot pick which Mythic appears, but this route yields one for certain rather than on a roll.

Mythic Unique Caches From Season Rank

The Season 15 Season Rank has nine ranks and 125 objectives, and its rewards include five Mythic Unique Caches plus up to ten Resplendent Sparks, with more Sparks inside the Mythic Caches. It costs no crafting materials, so check for unclaimed rank rewards before you start crafting. About 15% of the seasonal objectives require Lord of Hatred.

CUBE RECIPE

Five Steps to Craft a Mythic

5
STEP 01

1. Pick One of the Three Routes

Mythic Uniques can be created three ways: the Horadric Cube’s Upgrade Direct Item to Mythic, the Jeweler’s Rune Crafting > Mythic Uniques, and the Blacksmith’s Forge > Mythic Cache. Patch 3.2.1 kept all three methods and made the outcomes far more deterministic. The Cube costs more than the other two, but it is the only route whose result is fixed.

STEP 02

2. Unlock the Horadric Cube

To use the Cube route, unlock the Horadric Cube during the Lord of Hatred campaign. The recipe is not available with the base game alone. Unlock conditions and recipe visibility are covered in the Horadric Cube guide.

STEP 03

3. Finish the Item Before You Insert It

Upgrade Direct Item to Mythic is a 1:1 transfer, so bring the item to its final state first: the affixes you want, plus Tempering and Masterworking. Blizzard’s own example is a Tibault’s Will, which comes back as a Mythic version with all affixes and modifications retained. Because the result mirrors the input, feeding it a spare item only returns a Mythic spare.

TemperingMasterworkingUnique ItemMythic Unique
STEP 04

4. Do Not Transfigure the Candidate

The recipe cannot be used on an Unmodifiable item. Transfiguring an item locks its power and puts it out of scope, so do not Transfigure a candidate you intend to make Mythic. Blizzard has not published the Season 15 material cost, so do not carry over the four Pandemonium Fragments from Season 14 as this season’s price.

STEP 05

5. Use the Blacksmith for Iconic Mythics

Patch 3.2.1 added a second Blacksmith cache that rolls only Iconic Mythics, at the same cost as the Mythic Uniques cache. The 3.2.0 PTR had proposed turning the Mythic Uniques cache itself into a mix of class-appropriate Mythics and Iconic Mythics, but the streamlined Iconic-only route was kept instead. Neither cache guarantees a specific item.

Four Calls That Save Materials

4

Feed Your Best Item to Upgrade Direct

Unlike the 3.1-era Craft Mythic recipe, the Cube’s direct upgrade keeps the input item’s name, affixes, Greater Affixes, Tempering and Masterworking. The intended use is to feed it a finished main-slot item; there is no reason to feed it a spare. Read the recipe name in the Cube before you commit so you do not confuse the routes.

Unique ItemMythic UniqueHoradric CubeGreater Affix

You Only Get One Crafted Tag Slot

Because only one Crafted tag item can be equipped, spend the direct upgrade on the slot with the biggest payoff. For a second or third Mythic, use the untagged routes: the Jeweler’s Rune Crafting or the Blacksmith’s Mythic Unique cache. Decide which slot gets the tag before you start crafting.

Unique ItemMythic UniqueHoradric Cube

Estimate Cost Only From Published Facts

Blizzard states only that the Cube’s direct upgrade costs more than the Blacksmith or Jeweler recipes; it has not published the Season 15 materials or quantities. Do not carry over Season 14’s four Pandemonium Fragments as this season’s price. Read the material list in the recipe screen each time.

Mythic UniqueHoradric CubePandemonium Fragment

Separate What Is Fixed From What Is Random

The direct upgrade turns the input item itself into a Mythic, so neither the slot nor the name changes. The Blacksmith’s Mythic Unique cache, by contrast, rolls class-appropriate Mythics, and the Iconic-only cache is a separate second option. Do not lump the routes together as either all random or all deterministic.

Post-Craft Adjustment Rules

Enchant One Undesirable Affix

Unique, Mythic Unique, and Iconic Mythic items can have one undesirable affix altered through Enchanting. Review the guaranteed affixes and editable candidate before salvaging the result.

Added Affixes Roll at Maximum

Affixes added to a Mythic through Enchanting, Transfiguration, or Tempering roll at their maximum. The bug that allowed Transfiguration to replace existing Mythic affixes has been fixed.

No Chaotic or Focused Reroll

The 3.1.0 live update removed Chaotic and Focused Reroll for Unique and Mythic Unique items. Do not follow PTR or older Cube tables that still list those routes.

Check the Scope of the Two New Recipes

Season 15 added two Cube recipes. Affix Value Reroll rerolls every base affix on both gear and Talisman pieces while keeping Greater Affixes, Enchanted affixes, and powers gained from Tempering and Transfiguration (items locked by Transfiguration are out of scope). Horadric Reroll applies only to Legendary and better Charms and Seals, and never touches Set Bonuses or Unique/Mythic charm powers.

Base Game Only: Drops and Rank Caches

With the base game only, your routes are random drop sources, Lair Bosses, the Echo of Mephisto, and the Season Rank Mythic Unique Caches. The Cube’s direct upgrade requires the Horadric Cube, which is unlocked through Lord of Hatred.

One Key Slot for Certain: Direct Upgrade

If you already have one main-slot item finished with the affixes you want plus Tempering and Masterworking, the direct upgrade is the surest step. There are no random factors: the result is the Mythic version of exactly that item. Choose the slot knowing it consumes your single Crafted tag slot.

Several Slots: Jeweler and Blacksmith

Combining the untagged routes, the Jeweler’s Rune Crafting and the Blacksmith’s Mythic Unique cache, lets you equip several Mythics from crafted and dropped sources. Blizzard states both cost less than the Cube’s direct upgrade, but neither guarantees a specific item, so do not fix an expected number of attempts.

Iconic Mythics: Do Not Assume a Guarantee

Patch 3.2.1 added a second Blacksmith cache that rolls only Iconic Mythics, at the same cost as the Mythic Uniques cache. Neither the caches nor the Cube guarantees a specific item. Iconic Mythics remain Mythic-quality only, so do not plan a build around getting one early at Unique quality.

CAUTION

Costly Misreads

7
  • Do not carry the 3.1-era same-slot random conversion into how you read the Cube recipe. In 3.2.1, Upgrade Direct Item to Mythic is a 1:1 transfer that retains all affixes and modifications.
  • Do not try to equip two Crafted tag Mythics. Only one item made with the Cube’s direct upgrade can be equipped at a time.
  • Do not assume Mythics from the Jeweler or the Blacksmith’s caches also carry a Crafted tag. Only the Cube’s direct upgrade applies the tag.
  • Do not use Season 14’s four Pandemonium Fragments as the Season 15 price. Blizzard states only that the Cube costs more than the Blacksmith or Jeweler, and has not published the quantity.
  • Do not Transfigure a valuable Mythic candidate. The direct upgrade recipe cannot be used on an Unmodifiable item whose power has been locked by Transfiguration.
  • Do not present Unique Charms or Seals as things you can make Mythic. That was removed as unintended in 3.1.1a.
  • Do not build on Unique versions of Iconic Mythics. They were tried in the 3.2.0 PTR and dropped after player feedback.
LIVE UPDATE

Live 3.2.1 Corrections

6
  • Patch 3.2.1 shipped Upgrade Direct Item to Mythic, making the Cube route a 1:1 transfer that retains all affixes and modifications with no random factors. It cannot be used on an Unmodifiable item.
  • Patch 3.2.1 introduced a Crafted tag on Mythics made with the Cube’s direct upgrade, and only one Crafted tag item can be equipped at a time. Mythics from the Jeweler’s Rune Crafting and the Blacksmith’s Mythic Unique cache carry no tag.
  • Patch 3.2.1 kept Iconic Mythics at Mythic quality only and added a second Blacksmith cache that rolls Iconic Mythics exclusively, at the same cost as the Mythic Uniques cache.
  • Patch 3.2.1 limited Mythics from Initiate and Greater Lair Bosses and Belial’s Hoard to each boss’s own Unique item pool, and raised the Greater, Initiate and Belial drop rates. The Echo of Mephisto got better loot quality plus a guaranteed Mythic drop.
  • Patch 3.2.1 made all Unique items available to drop from level 1 in any difficulty and increased the chance for Mythic Uniques to drop from random sources. The rates themselves are not published.
  • For history: 3.1.0 made the conversion return the same slot, 3.1.1 cut the cost from five Fragments to four, 3.1.1a removed the one-crafted-Mythic equip limit, and 3.1.2 renamed the recipe to Craft Mythic. The 3.2.1 direct upgrade succeeds that line, and the single-equip limit is back in the form of the Crafted tag.
