Diablo 4 Guide: Season 14 Mythic Crafting – How to Roll Affixes, Upgrade Uniques, and Maximize Your Gear
Diablo 4 Season 14 introduces a comprehensive overhaul to the mythic unique system. Every unique item can now drop as a mythic version with completely randomized affixes. This guide covers the new system's mechanics, limitations, and optimal approaches to mythic crafting.

Overview of Season 14 Mythic Changes
Previously, mythic uniques possessed fixed affix pools with limited variance. In Season 14, the following changes apply:
Every unique can be a mythic unique — affixes are entirely randomized
Some items retain one guaranteed affix — for example, The Grandfather now always includes critical strike chance
Affix rerolling is available for mythics using the cube, similar to standard item crafting
Occultist enchanting is disabled for mythics — all rerolling occurs exclusively through the cube
Critical Note: The most significant nerf to existing mythics affects Harlequin Crest (Shako) . Its 80% damage multiplier has been reduced to 15%, and it no longer provides guaranteed cooldown reduction or damage reduction. This substantially reduces its universal applicability.
Permitted Actions for Mythic Items
Temper Application
Mythic items accept tempers like any other equipment. Greater Affixes can be added through standard tempering procedures.
Affix Rerolling via the Cube
The cube provides categorized reroll options:
Chaotic Reroll (Aggressive) – Replaces one offensive stat with another offensive stat
Chaotic Reroll (Defensive) – Replaces one defensive stat with another defensive stat
Chaotic Reroll (Utility) – Replaces one utility stat with another utility stat
Application Example: If a mythic possesses maximum life (a defensive stat) and damage reduction is preferred, using a defensive chaotic reroll targets that category specifically. This provides controlled modification rather than complete randomness.
Socket Addition
Sockets can be added to mythics through normal means.
Unique-to-Mythic Upgrade
Using a new material, regular uniques can be upgraded to random mythics within the same category (weapon, armor, or jewelry). Important restrictions apply:
Same item type is not guaranteed — upgrading an Azurewrath produces a random mythic axe, not a mythic Azurewrath
Armor upgrades involve extensive randomness — the pool contains 20-30 unique armors, making specific target acquisition improbable
Weapons offer marginally better odds — approximately 10-15 uniques exist in the weapon pool, yielding roughly 1-in-10 chances for a specific mythic weapon
Rings and amulets feature approximately 10-12 options in their respective pools
Prohibited Actions for Mythic Items
Occultist Enchanting
Mythic affixes cannot be rerolled at the Occultist. The enchant interface is disabled for all mythic items, including those with Greater Affixes.
Affix Locking
Unlike legendary items, affixes on mythics cannot be locked to protect them during rerolls. Each reroll carries the risk of removing desirable stats.
Unique Power Rerolling
The unique power (special effect) cannot be rerolled. Damage values on unique powers are fixed and remain unaffected by affix modifications.
Critical Mechanics
Greater Affix Limitations
When a mythic possesses a Greater Affix, such as The Grandfather's guaranteed critical strike chance, it cannot be locked through enchanting. All rerolls risk removing that Greater Affix.
Affix Pool Restrictions
When rerolling, the new affix must originate from that item category's natural pool. For example:
Critical strike chance cannot be rolled on weapons that do not naturally permit it, with the exception of offhand items such as focuses or shields
Consequently, certain stats are unobtainable through rerolls and must appear on the initial drop
Salvaging Mythics
Salvaging a mythic unique continues to yield a spark, consistent with previous seasons. This remains a reliable method for acquiring crafting materials for mythic recipes.
Analysis of the Upgrade-to-Mythic System
The upgrade mechanic, while conceptually appealing, has generated community concern for several reasons:
Issue 1: No Same-Item Guarantee
Upgrading an Azurewrath (a sword) logically suggests a mythic Azurewrath as the outcome. Instead, the result is a random mythic sword. This breaks the expected connection between the invested item and the resulting output.
Issue 2: Excessive Armor Pool Size
With 20-30 unique armors in the pool, the probability of obtaining a specific mythic armor is approximately 1 in 30. This renders targeted farming exceptionally difficult.
Issue 3: Material Rarity Uncertainty
The material required for upgrades is new. If it proves common, the randomness becomes manageable. If its rarity matches that of legendary runes, which require 6 Vex runes per craft, the system will feel punishing rather than rewarding.
Issue 4: Legendary Rune Costs Remain Prohibitive
The traditional rune recipe for mythic crafting still requires 6 Vex runes. Given the extremely low drop rates of legendary runes, this cost remains prohibitive for most players, particularly when the result is random.
Community Reception
Positive reception: Players generally approve of the ability to reroll affixes on mythics. Having control over item stats represents a constructive change.
Strong criticism regarding upgrades: The community overwhelmingly believes that upgrading a unique should guarantee the mythic version of that same unique. Receiving a random mythic cleaver from upgrading an Azurewrath is perceived as unsatisfactory.
Concerns about excessive randomness: The new system introduces multiple layers of randomness — random drops, random affixes, random upgrade outcomes, and random reroll results. This makes pursuing a specific mythic feel akin to a lottery.
Recommendations
For casual players: Await the official season launch and community testing results. The PTR exists for feedback, and Blizzard may adjust drop rates and mechanics before the live release.
For crafters: Focus on the reroll system rather than the upgrade system. Rerolling affixes provides the greatest control over existing mythics. The upgrade system currently lacks reliability as a source of specific mythic items.
Conclusion
Season 14's mythic changes represent progress toward greater crafting control, but the upgrade system requires refinement. The affix rerolling capability is genuinely beneficial — players can now customize mythics to suit specific build requirements, though acquiring and rolling multiple high-tier mythics can still be costly in terms of Diablo 4 Gold. If you're looking to fund your crafting projects without endless farming, MMOEXP is a reliable source for Diablo 4 Gold to help you reach your goals faster.
