Season 15 of Diablo 4, dubbed Hell's Legacy, has brought a wave of crafting content that pulls heavily from classic Diablo lore. From reworked Mythic Unique crafting to hidden runeword recipes ripped straight from the pages of Diablo 2, the Horadric Cube has become the busiest bench in Sanctuary this patch. Players are still uncovering new combinations from the game files, and the list keeps growing.

Below you'll find the Diablo 4 Season 15 Horadric Cube Recipes & Craft Guide, covering new recipes, secret Legacy Runeword formulas, Mythic Unique upgrades, rune upgrading tricks, affix reroll tactics, and the biggest hidden combinations players are using right now.

Changes to Horadric Cube Crafting in Diablo 4 Season 15

The developers rolled out several updates to the Horadric Cube system, ranging from Mythic Unique creation to affix rerolls and material drop rates. Here's what's new.

Mythic Unique Crafting Is Now Deterministic

While the methods to create Mythic Uniques remain the same, the outcomes are far more deterministic in Season 15. Mythic Uniques can be created three ways:

• Horadric Cube: Upgrade Direct Item to Mythic

• Jeweler: Rune Crafting > Mythic Uniques

• Blacksmith: Forge > Mythic Cache

The Upgrade Direct Item to Mythic recipe in the Cube costs more than the other options, but it delivers a total 1:1 transfer. Put a Tibault's Will with ideal affixes, Tempering, and Masterworking into the Cube, and you'll get a Mythic-ized version with everything retained. The only restriction is that you cannot use this recipe on an Unmodifiable item.

Mythic Uniques created this way carry a Crafted tag, and you can only equip one Crafted item at a time. Mythic Uniques from the Jeweler or Blacksmith do not have this tag.

Two New Affix Reroll Recipes

Two new recipes give you more control over unwanted affixes while protecting the traits you want to keep:

• Affix Value Reroll: Rerolls all base affixes on equipment and Talisman items (Charms and Seals), while protecting Greater Affixes, Enchanted affixes, Tempers, and Transfigurations.

• Horadric Reroll: A second option for Legendary+ Charms and Seals that fully randomizes base Affixes without touching Set Bonuses or Unique/Mythic charm powers.

Material and Cost Adjustments

Blizzard also tuned the economy around Cube crafting. Pure Primordial Dust drop weighting was reduced due to higher baseline Legendary drop rates, while Coarse Primordial Dust becomes less common as difficulty rises. Refined, Volatile, Pure, Enhanced, and Attuned Primordial Dust all become more common at higher difficulties. Royal Gems now cost 10 Forgotten Souls (down from 30), and Grand Gems dropped from 300 to 50.

Notable Bug Fixes

Unique Charms and Unique Items can now have their powers rerolled through the Cube, and Mythic Amulets no longer receive non-maximum Unique Affix values when first Transfigured.

With the systemic changes covered, let's look at the brand-new recipes players can craft this season.

Diablo 4 Season 15 New Horadric Cube Crafting Recipes

The headline addition this season is the return of Legacy Runewords, a system pulled directly from Diablo 2 Lord of Destruction. There are also new rune upgrade recipes that operate on hidden rules borrowed from the original game.

How Legacy Runewords Work

These new runewords are crafted by placing a compatible common-quality white base item plus the listed runes into the Horadric Cube. Ancestral white bases are preferred since they roll higher item power and can carry Greater Affixes. If the combo is valid, the Cube may show the recipe as "???" before transmuting. The finished runewords behave like Unique items, so you can transmute them, socket them, and enchant them just like any other Unique. Note that no sockets are required on the base item, and they cannot be tempered.

Season 15 added 12 new runes to support this system: Amn, Eth, Mal, Ort, Tal, Ber, Ist, Ith, Lo, Ral, Sol, and Tir.

The 19 Legacy Runeword Recipes (Rune Combos & Base Items)

Below is the full list of documented Season 15 Legacy Runeword recipes:

With 84 item variants across the 19 runewords, since some recipes work on multiple base types, there's plenty of room for experimentation.

Runewords Worth Prioritizing

• Enigma works for every build thanks to +2 all skills, damage reduction, movement speed, percentage maximum life, and the evade-as-sorceress-teleport effect.

• Spirit is the top pick for any class that can wield a shield or off-hand, delivering all skills, attack speed, max life, and maximum resource.

• Call to Arms is close to mandatory for shout-based Barbarians, granting +5 ranks to all skills.

• Rain is the Druid favorite with +5 to nature magic skills and a chance to launch tornadoes on hit.

Where to Farm Runes

Runes drop across the world in Helltides and from the Tree of Whispers (currently bugged), but the top source is the Prime Evils. Once you reach Torment 10, their portals turn from yellow to red and open the Hell difficulty version of the fight. Being Torment 12 strong is recommended before challenging them.

Baal in the Worldstone Keep is currently the go-to farm target because the run can be finished in about two minutes with an optimized path. Beyond dropping every rune in the pool, Prime Evils also shower players in Mythic drops, Mythic Seals, and Greater Affix gear.

Beyond the runewords, some of the most interesting finds this season are the hidden recipes that reveal nothing until the correct ingredients are placed in the Cube.

Diablo 4 Season 15 Secret Horadric Cube Crafting Recipes

Season 15 leaned hard into hidden content, and the Cube is packed with recipes that display no hint until the right items are combined. These fall into two groups: hidden item recipes and hidden rune upgrades.

Hidden Item Recipes

These recipes only run while Season 15 is active, and they show nothing in the interface until the correct Horadric Cube crafting materials are placed inside:

The Wirt's Lucky Coins recipe is particularly noteworthy since it feeds directly into the Echo of Tristram secret. Combine one Splinter of Terror, one of Destruction, and one of Hatred, then take the resulting coin into Deckard Cain's Memory. Toss it into the Tristram fountain to open a new pinnacle boss fight against Diablo, Baal, and Mephisto at once, which then rewards the Hellfire Torch.

Uber Anihilus and Bovine Armor

Community datamines confirm a hidden Uber Anihilus Mythic Horadric Seal, accessible through a longer hunt that involves completing the Terror shard route and defeating each of the three Prime Evils to build up to it. Bovine Armor and the return of the secret cow level (called Moo Fist by players) also live behind Cube combinations that are still being pieced together.

Hidden Rune Upgrade Recipes

The rune upgrades are hidden the same way, and there are fourteen of them. They form two separate runs rather than one continuous ladder, so no recipe joins Sol to Mal. The system follows the classic Diablo 2 "Talsarid" mnemonic (Topaz, Amethyst, Sapphire, Ruby, Emerald, Diamond), shifted up one gem tier since Diablo 4 starts at Crude rather than Chipped.

Crafting Runes You Don't Have

The Jeweler has a full rune crafting recipe for players missing a specific top-tier rune. Combining five of any rare rune + five of any Legendary Rune of Ritual + one Cham rune produces a Jah rune outright. If you're short on Legendary Runes of Ritual, run the Under City with Tributes of Harmony, which spit out runes ranging from rare to legendary. Lesser Tributes of Harmony can be amalgamated up in the Cube (five to one), and the Alchemist can build lower tributes using Runic Dust obtained from salvaging Infernal Compasses and Nightmare Dungeon Keys.

Magic runes are also worth keeping. A three-to-one transmute converts them to a random magic rune, and amalgamation lets you upcycle low-value runes like Mo into Nago, or Yul into Nok. Stacking five rares like Lum or Neo you don't use lets you amalgamate up to something like Eom for target-crafting.

The Stealth-to-Enigma Trick Has Been Patched

In the first days of the season, transmuting three Stealth runewords together produced an Enigma-style teleport on the output, apparently because Stealth and Enigma shared the same icon in the files. That shortcut no longer works. Blizzard fixed the interaction, so the only way to get the Enigma teleport now is to craft Enigma directly with Jah + Ith + Ber on a chest armor base.

Items To Craft Through Horadric Cube & How To Craft in Season 15

Between runewords, rune upgrades, Mythic Uniques, and hidden consumables, there's a lot to build. Below, we are going to walk through each crafting step by step.

Crafting a Legacy Runeword

The process is simple once you have your materials ready:

1. Choose your target runeword and check its recipe (visible at the bottom of the tooltip on existing runewords).

2. Gather the required runes. For example, Stealth needs Tal + Eth, while Enigma needs Jah + Ith + Ber.

3. Obtain a compatible base item. This must be a white or gray common-quality item of the correct type. For Stealth, that means a chest armor base. Gambling for white/gray/blue items is the fastest route, and blue items can be cleaned up using the remove affix command in the Cube.

4. Place everything in the Horadric Cube one item at a time, then hit Transmute. The result is your finished runeword, which behaves like a Unique.

Crafting a Mythic Unique via Direct Upgrade

For players who already have a perfectly rolled Unique they want to push to Mythic:

1. Confirm the item is not Unmodifiable (avoid Transfiguring the item first).

2. Place it in the Horadric Cube and use the Upgrade Direct Item to Mythic recipe.

3. The result carries the Crafted tag, and only one Crafted item can be equipped at a time.

Upgrading Runes

To move up the rune tree, follow the shifted "Talsarid" gem pattern:

• Runes below Sol: Combine three of the same rune (no gem needed for the six lowest tiers).

• Sol and above: Combine three of the rune plus the appropriate Chipped gem.

• Ist and above: Combine two of the rune plus a Flawless gem.

• Ber and above: Combine two of the rune plus a Grand gem.

The Greater Affix Lock Trick (Perfect Glove Crafting)

One of the most powerful moves this season is protecting a good roll before rerolling the rest of the item. The workflow looks like this:

1. Take a piece with one good stat (for example, crit strike damage on gloves) to the Occultist.

2. Open Enchant, select the stat you want to protect, then choose No Change. The stat is now locked in place.

3. Head to the Horadric Cube. You can now use Remove Affix freely, and Aggressive Tuning Prisms will never overwrite the locked stat.

4. Add a new affix with the appropriate Tuning Prism, then Focus Reroll it until it turns into the exact stat you want (crit chance, vulnerable damage, all damage, etc.).

5. Repeat for the remaining slots. The trade-off is that a locked stat cannot be rerolled at the Occultist, so pick something you truly want to keep.

The All Skills Amulet Trick

If you don't need a specific Mythic amulet, there is a repeatable route to a perfect all-skills amulet:

1. Start with an amulet that already has crit damage multiplier (or another core stat).

2. Use Aggressive Tuning Prisms to add core skills.

3. Add another affix rolled as your core stat.

4. Add a third affix, which will always roll into All Skills every single time as long as the other slots are filled correctly.

5. If the All Skills roll is low, lock core skills at the Occultist with No Change, then remove and re-add affixes at the Cube until All Skills rolls high.

6. Finish by rerolling the leftover willpower/core stat slot into your ideal value, masterwork to hit crit damage, then transfigure for a chance at another Greater Affix.

Rerolling Charms and Seals

Season 15 introduced two new options for talisman upgrades that many players missed:

• Reroll Set Charm (50 Infused Horadric Resin): Randomizes the charm to another one in the set. Best when you own few Greater Affix charms and want to fish across the whole set.

• Horadric Reroll (100 Infused Horadric Resin + Primordial Dust): Fully randomizes the base affixes on a specific charm or seal while keeping the identity of the charm (a Lyndon stays a Lyndon). Perfect when you only need to fix one charm's rolls, since it saves resources on the ones you already have finished.

• Affix Value Reroll (Tuned Primordial Dust): Randomizes only the values of the base affixes at once. Great for pushing rolls higher without changing which affixes are present. Holding F speeds up bulk rerolling.

Working With Seals

For seals, the three-to-one transmute is still the best way to fish for +1 Charm Slots. Throw in three seals you don't need and pray for the roll. Once you land a +1 Charm Slots seal, Affix Value Reroll can push the numeric roll higher, and Horadric Reroll can rework the base affixes into damage percent, crit damage, all stats, or whatever your build values most.

Legendary and Mythic seals with a base like Flesh of Abaddon can be pushed into 20%+ separate damage multipliers this way. A common cook is: reroll to Damage or Crit Damage via Horadric Reroll, then Affix Value Reroll until the number peaks. Materials are cheap (roughly 100 blue primordial dust per attempt) and Tuned Primordial Dust drops readily from Under City Tributes of Ingenuity and Escalating Nightmare Dungeons with the Material Reserve modifier.

Filling Out Your Charm Set

If you're still missing charms for your set, put any three charms in the Cube and hit three-to-one transmute for a random charm from the set. It's gambling, but it's the fastest path to completion.

Amalgamating Splinters and Soulstones

Hellfire Splinters and Soulstones can be amalgamated up through tiers in the Cube. A common cook is upgrading Black Soulstone shards step by step until you reach the Legendary and then Unique versions. The Unique Black Soulstone slotted into a helm is a huge damage boost, and current Warlock leaderboard clears are built around it. Note that Hellfire Torches cannot have their affixes rerolled directly, but three of them can be recycled into a new one via three-to-one transmute.

Crafting Hidden Items

The hidden recipes require no menu, no unlock, and no discovery step. Just place the exact ingredients in the Cube and hit Transmute. If the combination is valid, the Cube will process it. If not, nothing happens. This mirrors the way Diablo 2 handled hidden Horadric Cube recipes, and it means the community is likely still finding new combinations weeks after the season's launch.

Between the new Legacy Runewords, the hidden rune upgrades, the affix reroll options, and the trail of secret consumables like Wirt's Lucky Coins and Liquid Rainbow, the Horadric Cube in Season 15 is the most active it's ever been. Keep your rare consumables, save your white bases, and try any strange combinations you come across, since Season 15 has proven that if it looks like a Diablo 2 recipe, it probably works.
