Kanai’s Cube is Diablo 3’s most powerful crafting tool — a legendary artifact that lets you extract the power from any Legendary or Set item and equip that power passively, essentially giving your character up to three extra item effects without wearing those items. Every serious Diablo 3 build uses it, and getting it requires a short trip to the Ruins of Sescheron in Act III.
- Allows extracting Legendary power from any Legendary/Set item (destroys the item)
- Three passive power slots: weapon, armour, jewellery — one equipped power from each category
- Located in the Ruins of Sescheron in Act III
- Available to all players once found — no character level requirement
- Used for rerolling stats, upgrading rares to Legendary, and converting set items
How to Get Kanai’s Cube in Diablo 3
Kanai’s Cube is found in the Royal Quarters of the Elder Sanctum, inside the Ruins of Sescheron in Act III. It doesn’t require any quest progress — you can retrieve it on any difficulty.
Step-by-step:
- Start or load into Act III from the map screen
- Select Adventure Mode (if available) or Story Mode — either works
- Travel to the Ruins of Sescheron waypoint (Act III, north of Bastion’s Keep)
- Navigate through the Ruins of Sescheron until you find the Elder Sanctum dungeon entrance
- Inside the Elder Sanctum, find the Royal Quarters — Kanai’s Cube sits on a pedestal in the main chamber
- Click the cube to add it to your inventory and unlock it permanently
ℹ️ Kanai’s Cube is account-wide across all characters and difficulties once retrieved. You only need to find it once — it then appears in the items screen for every character.
How to Use Kanai’s Cube
The cube has six main functions accessed through Zoltun Kulle, who appears near the cube in town:
| Function | What It Does | Cost |
|---|---|---|
| Extract Legendary Power | Strips power from a Legendary/Set item | Destroys the item + materials |
| Equip Extracted Power | Passively apply an extracted power | Free (manage in cube UI) |
| Reforge Legendary | Reroll all stats on a Legendary item | High material cost |
| Upgrade Rare to Legendary | Converts a yellow item to class-appropriate Legendary | Materials |
| Convert Set Item | Exchange one piece for another from same set | Set items + materials |
| Remove Level Requirement | Allows low-level characters to use high-level items | Gold + materials |
The «Equip Extracted Power» function is the cube’s most impactful use — building three passive legendary powers on top of your equipped gear opens enormous build flexibility.
Diablo 3 Kanai’s Cube FAQ
Below are the most common questions about Kanai’s Cube in Diablo 3.
Do You Need a Specific Difficulty for Kanai’s Cube?
No — Kanai’s Cube can be retrieved on any difficulty, including Normal. There’s no power level requirement. Most players grab it on their first character early in the campaign or at the start of a new season.
Can You Use Kanai’s Cube in Seasons?
Yes — Kanai’s Cube functions identically in both seasonal and non-seasonal play. In Seasons, you must re-retrieve it if it’s your first seasonal character (it’s account-wide but the seasonal fresh start applies). Re-retrieving takes under 10 minutes.
What Is the Best Kanai’s Cube Power Setup?
Build-dependent entirely. The cube powers directly enable many top-tier builds — the «Cube power» combinations are as important as the equipped gear in many cases. Check maxroll.gg or Icy Veins for current season tier lists that include recommended Cube powers per class.
How Do You Farm Materials for Kanai’s Cube?
The main crafting materials (Forgotten Souls, Arcane Dust, Veiled Crystal, Death’s Breath) drop from monsters and salvaging items. Death’s Breath is the bottleneck — it drops from elites and champions in Torment difficulty and higher. Farm Nephalem Rifts on Torment I+ for consistent material income.
Does Kanai’s Cube Work in Diablo 4?
No — Kanai’s Cube is Diablo 3 exclusive. Diablo 4 has its own item system without an equivalent artifact. The cube’s power-extraction concept influenced Diablo 4’s design but isn’t directly present in the sequel.
Kanai’s Cube is one of gaming’s most elegantly designed crafting systems — turning item acquisition from pure slot-filling into a layered decision about which powers to extract, combine, and build around.
