Crafting in Diablo 4 is spread across several vendors and systems, so it is easy to lose track of which recipe belongs where. This cheat sheet keeps the important recipes in one place: Mythic crafting, Horadric Cube upgrades, gem fragment conversion, rune crafting, and useful item caches.
It helps you decide which materials to keep, which recipes are worth prioritizing, and where to convert excess resources into something more useful.
Quick Crafting Overview
Start here if you only need to know which vendor or system handles each crafting category.
Vendor / System | Main crafts | When to use it |
Blacksmith | Random Mythic Unique / equipment-related crafts | Useful when you want to spend Resplendent Sparks or craft gear caches. |
Jeweler | Targeted Mythic Unique crafting and Gem Conversion | Best for specific Mythic Unique recipes and turning spare gem fragments into another type. |
Horadric Cube | Amalgamation and Rune Crafting | Used for upgrading groups of items, converting runes, and working with boss trophies. |
Occultist | Nightmare Sigils | Relevant when preparing dungeon entries. |
Alchemist | Crafting material upgrades | Useful for improving or converting materials depending on what you need. |
Best Materials to Watch
Several recipes repeat the same material patterns. When cleaning your stash or planning a craft, pay extra attention to these resources:
- Resplendent Spark — required for every Mythic Unique craft listed here.
- Runes — used for targeted Mythic crafts and Rune Crafting recipes.
- Gem Fragments — used for Gem Conversion and the Legendary Amulet Cache.
- Forgotten Soul — appears in both cache recipes.
- Boss Trophies — can be converted through Amalgamation into boss-specific Unique rewards.
Mythic Unique Crafting
Mythic crafting is the most important section if you are trying to target a specific chase item. Every listed Mythic craft requires 2 Resplendent Sparks, while targeted crafts also require specific rune combinations.
The random Mythic Unique option is cheaper to understand but less controlled: it costs 2 Resplendent Sparks and 50,000,000 Gold. Targeted crafts give you a specific item, but they require the matching rune set.
Mythic Item | Materials Required |

Horadric Cube Recipes
The Horadric Cube handles several conversion-style recipes. The main idea is simple: turn a group of lower-value or duplicate items into a higher-value result, whether that is a rune, tribute, sigil, or boss-specific Unique reward.
Amalgamation Recipes
Amalgamation recipes use a 5-to-1 structure. This is useful when you have stacks of the same type of item and want to push them into a higher rarity or a more focused reward.
Input | Output |
5x any Nightmare Sigils | 1x Escalation Sigil |
5x any Magic Runes | 1x random Rare Rune |
5x any Rare Runes | 1x random Legendary Rune |
5x same Magic Tributes | 1x Rare Tribute of the same type |
5x same Rare Tributes | 1x Legendary Tribute of the same type |
5x same Boss Trophy | 1x random Unique from that Boss |
Rune Crafting Recipes
Rune crafting lets you target a listed rune recipe by combining a specific rune with additional Rare and Legendary runes. This section is especially useful when planning Mythic Unique crafts that require exact rune names.

Specific Rune Conversion Chances
If you are converting duplicates rather than using a named recipe, the outcome depends on the starting rune quality.
Recipe | Runes Received |
3 of a specific Legendary Rune for 1 Rune | 100% chance for 1 Random Rune of Legendary Quality |
3 of a specific Rare Rune for 1 Rune | 85% chance for 1 Random Rune of Rare Quality 15% chance for 1 Random Rune of Legendary Quality |
3 of a specific Magic Rune for 1 Rune | 85% chance for 1 Random Rune of Magic Quality 15% chance for 1 Random Rune of Rare Quality |
Gem Fragment Conversion
Gem Conversion is handled at the Jeweler and lets you turn one fragment type into another. Each recipe creates 200 fragments of the target type by consuming three different fragment types at 100 each.
This is useful when one gem color is blocking your crafting plan while your stash is overloaded with other fragment types.
Recipe | Materials Required |
Amethyst Fragment x 200 | |
Diamond Fragment x 200 | |
Emerald Fragment x 200 | |
Ruby Fragment x 200 | |
Sapphire Fragment x 200 | |
Skull Fragment x 200 | |
Topaz Fragment x 200 |
Accessory and Blacksmith Caches
Cache recipes consume bulk materials and return a focused gear reward. They are best used after your core Mythic, rune, and gem crafting needs are already covered.
Recipe | Materials Required |
- Gem Fragments x30,000 - Forgotten Soul x60 | |
Crafting Priority Tips
- For Mythic items: check whether you want the random Mythic craft or a targeted recipe first. Targeted crafts require the right rune combination.
- For runes: avoid spending key runes blindly if they are part of a Mythic recipe you plan to craft later.
- For gems: use conversion only when you need a specific fragment type; otherwise, keep a balanced stockpile.
- For boss trophies: save matching trophies if you want to turn them into a random Unique from that boss.
- For caches: treat them as a material sink once your core crafting needs are already covered.
FAQ
Where do I craft Mythic Uniques?
The random Mythic Unique craft is listed under the Blacksmith, while the targeted Mythic recipes are listed under the Jeweler.
How many Resplendent Sparks do Mythic crafts require?
Every Mythic Unique craft in this cheat sheet requires 2 Resplendent Sparks.
What is Amalgamation used for?
Amalgamation converts groups of 5 matching or compatible items into a higher-rarity or more focused reward, such as upgraded runes, tributes, sigils, or boss-specific Unique rewards.
How does Gem Conversion work?
Each Gem Conversion recipe creates 200 fragments of one gem type by consuming 100 fragments of three other gem types.
Should I use Rune Crafting or save runes?
Save runes first if they are part of a targeted Mythic Unique recipe you want. Use Rune Crafting when you have duplicate or excess runes that do not block your current goal.
