Horadric Cube – All Prisms & Affix Pools Explained

With **Diablo 4: Lord of Hatred**, the **Horadric Cube** was introduced as a new crafting system. One of the most important mechanics within this system are the so-called **Tuning Prisms**. These Prisms help you influence crafting results in the Horadric Cube more precisely. Instead of changing an affix completely at random, you can use the right Prism to target a specific affix category. [info] Simply put: The Prism determines the direction of your crafting. [/info] --- ## What Do Tuning Prisms Do? Tuning Prisms influence which type of affix is changed, removed, or rerolled when crafting with the Horadric Cube. For example, if you want to affect an offensive stat, you use an **Aggressive Tuning Prism**. If you want to affect a defensive stat, you use a **Protector’s Tuning Prism**. This makes crafting more predictable and helps you work toward better items more efficiently. --- ## Overview of All Prisms | **Aggressive Tuning Prism** | Offensive Affixes | Damage, Crit, Attack Speed, Damage Multipliers | | **Protector’s Tuning Prism** | Defensive Affixes | Life, Armor, Resistances, Damage Reduction | | **Chromatic Tuning Prism** | Individual Resistances | Fire, Cold, Lightning, Poison, Shadow, Physical Resistance | | **Resourceful Tuning Prism** | Resource Affixes | Resource, Resource Generation, Cost Reduction | | **Pragmatic Tuning Prism** | Utility & Mobility | Movement, Evade, Cooldown Reduction, Lucky Hit | | **Adept’s Tuning Prism** | Skill Ranks & Attributes | Skill Ranks and Main Attributes | | **Entropic Tuning Prism** | Safer Transfiguration | Safer Transfiguration with lower risk | | **Kullean Tuning Prism** | Amulet Special Case | Adds a Legendary Affix to amulets | --- ## Aggressive Tuning Prism The **Aggressive Tuning Prism** targets offensive affixes. ### Typical Affixes - Weapon Damage - Attack Speed - Critical Strike Chance - Critical Strike Damage - Vulnerable Damage - Damage Over Time - Fire Damage - Physical Damage - Shadow Damage - Total Damage Multiplier - Thorns - Willpower ### When Should You Use It? Use this Prism when you want to improve your item offensively. Especially useful for: - Weapons - Rings - Gloves - Amulets - offensive build optimization - more damage in the endgame [info] In short: Aggressive = everything that directly or indirectly increases your damage. [/info] --- ## Protector’s Tuning Prism The **Protector’s Tuning Prism** targets defensive affixes. ### Typical Affixes - Maximum Life - Life Regeneration - Life on Hit - Life per Kill - Armor - Resistance to All Elements - Fire Resistance - Cold Resistance - Lightning Resistance - Poison Resistance - Shadow Resistance - Physical Resistance - Damage Reduction - Dodge Chance ### When Should You Use It?

[/info] --- ## Chromatic Tuning Prism The **Chromatic Tuning Prism** targets individual resistances. ### Typical Affixes - Fire Resistance - Cold Resistance - Lightning Resistance - Poison Resistance - Shadow Resistance - Physical Resistance [warning] The Chromatic Tuning Prism is not simply “all defensive affixes”. It mainly targets individual resistances. **Resistance to All Elements** belongs more to the general defensive category and not directly to the pure Chromatic pool. [/warning] ### When Should You Use It? Use this Prism when you are missing a specific resistance. Examples: - you have too little Fire Resistance - you need more Poison Resistance - your build is weak against certain damage types [info] In short: Chromatic = targeted resistances against specific damage types. [/info] --- ## Resourceful Tuning Prism The **Resourceful Tuning Prism** targets resource-related affixes. ### Typical Affixes - Maximum Resource - Resource per X Kills - Resource Generation - Resource Cost Reduction - Lucky Hit: Restore Primary Resource ### When Should You Use It? Use this Prism when your build has resource problems. Especially useful for builds that: - often run out of resource - have high resource costs - want to spam skills consistently - rely heavily on resource generation [info] In short: Resourceful = everything that improves your resource or lowers your costs. [/info] --- ## Pragmatic Tuning Prism The **Pragmatic Tuning Prism** targets utility, movement, and comfort stats. ### Typical Affixes - Movement Speed - Attacks Reduce Evade Cooldown - Maximum Evade Charges - Evade Grants Movement Speed - Potion Capacity - Lucky Hit Chance - Healing Received - Cooldown Reduction - Impairment Reduction ### When Should You Use It? Use this Prism when you want your build to feel smoother, faster, or more flexible.

[/info] --- ## Adept’s Tuning Prism The **Adept’s Tuning Prism** targets skill ranks and main attributes. ### Typical Affixes - +Ranks to specific skills - +Ranks to Basic Skills - +Ranks to Core Skills - +Ranks to class-specific skill categories - Strength - Dexterity - Intelligence - Willpower ### When Should You Use It? Use this Prism when your build strongly benefits from skill ranks or main attributes. Especially useful for: - Gloves - Amulets - Helmets - class-specific builds - builds with important damage skills - reaching breakpoints through skill ranks [info] In short: Adept = skill ranks and main attributes. [/info] --- ## Entropic Tuning Prism The **Entropic Tuning Prism** is a special case. It does not belong to the normal affix categories. Instead, it affects **Transfiguration**. ### Effect The Entropic Tuning Prism removes the riskiest, but also the strongest possible Transfiguration outcomes. This means: - less risk - fewer extreme negative outcomes - but also less chance for absolute top-tier results - the item may become permanently unmodifiable afterward ### When Should You Use It? Use this Prism when you have a good item but want to reduce the risk of a completely bad Transfiguration result. [info] In short: Entropic = safer, but with less jackpot potential. [/info] --- ## Kullean Tuning Prism The **Kullean Tuning Prism** is also a special case. It is mainly used in connection with amulets. ### Effect Kullean’s Prism can add an additional Legendary Affix to an amulet. Important: - only relevant for amulets - not intended for Uniques - can create a very powerful result - especially interesting for endgame min-maxing ### When Should You Use It? Use this Prism when you want to further improve an already very strong amulet. Especially useful for: - perfect amulets - endgame builds - min-maxing - builds that benefit from an additional powerful Legendary effect [info] In short: Kullean = special amulet Prism for additional Legendary power. [/info] --- ## Which Prism Should You Use? ### If You Need More Damage Use: - **Aggressive Tuning Prism** - possibly **Adept’s Tuning Prism**, if skill ranks are important Best for: - Weapons - Rings - Gloves - Amulets --- ### If You Die Too Quickly Use: - **Protector’s Tuning Prism** - **Chromatic Tuning Prism**, if you are missing specific resistances Best for: - Chest Armor - Pants - Helmets - Amulets - defensive item slots --- ### If Your Build Has Resource Problems Use: - **Resourceful Tuning Prism** Best for: - Rings - Amulets - resource-heavy builds - builds with high skill costs --- ### If Your Build Feels Slow or Clunky Use: - **Pragmatic Tuning Prism** Best for: - Boots - Amulets - Gloves - speedfarming builds - cooldown-heavy builds --- ### If You Need Skill Ranks Use: - **Adept’s Tuning Prism** Best for: - Gloves - Helmets - Amulets - builds that scale strongly with skill ranks --- ## Quick Summary Aggressive = Damage, Crit, Attack Speed, Damage Multipliers Protector = Life, Armor, Damage Reduction, Resistances Chromatic = individual resistances like Fire, Cold, Lightning, Poison, Shadow, Physical Resourceful = Resource, Resource Generation, Resource Cost Reduction Pragmatic = Movement, Evade, Cooldown Reduction, Lucky Hit, Utility Adept = Skill Ranks and Main Attributes Entropic = safer Transfiguration, but without absolute top-tier outcomes Kullean = special amulet Prism for an additional Legendary Affix
