Kanai's cube interface

Kanai's Cube is an ancient device found in the Tomb of King Kanai in Diablo III. It will be added in patch 2.3.0.

Lore

This device was the most prized possession of King Kanai, buried beneath the Ruins of Sescheron. Originally, the Cube's design was used to create the Horadric Cube, a less potent version of it.

The device has been retrieved by the Nephalem, and Zoltun Kulle's spirit was able to unlock its power.

In-game

Players may obtain the Cube if they survive through what remains of Sescheron and open the ancient king's lost tomb, The Immortal Throne.

The Cube itself functions much like an artisan once acquired, and will be available for use by all heroes on the account (effectively being a fourth artisan). It has several potent abilities, including, but not limited to:

• Breaking down Legendary items for players to equip their special effects as passive traits.
• Conversion of crafting materials from one type to another.
• Conversion of gems.
• Opening portals to Whimsyshire / Whimsydale, Treasure Realm and Not The Cow Level.
• Rerolling all affixes on a Legendary item (Reforging).
• Conversion of Set items into other items of the same set.
• Upgrading Rare items into Legendary items.
• Removal of Character Level Requirements.

Legendary Abilities: Archive of Tal Rasha

The abilities extracted from Legendary items are stored within the Cube, and are not lost if replaced. While characters may only have up to 3 of them active, they can store all acquired essences within the cube, swapping them at any time when in town without losing essences they override.

• Only one weapon effect, one armor effect, and one jewelry effect may be active at any time.
• In addition, legendary powers are Unique Equipped; as a result, one cannot gain the same power both from the Cube and from an equipped item.
• The passive traits granted by the Cube are completely independent from the character's actual passive skills, and use specialized slots that only fit for these traits.
• Armor includes Boots, Pants, Helmet, Shoulders, Bracers, Chest Armor, Gloves and Belts. Weapons also include all off-hand items (Quivers, Mojos, Sources, Shields).
• Weapon being one-handed or two-handed makes no difference: it will still count as a single essence.
• One cannot equip a Legendary Affix that is specifically designed for another class, or is bound to a class-specific item, or to an item that the character cannot use for any reason.
• Ancestor's Grace and Hellfire Amulet passives cannot be extracted into the Cube. Neither can the effects of Legendary Gems.
• Affixes with variable rolls retain their maximum roll in the Cube, so extracting is only performed once per item.
• The Cube interface shows players what Legendary Powers they are missing.
• Cannot extract Set properties, and cannot extract Legendary properties of Set items (such as those of Danetta's Hatred crossbows).
• For all purposes, the effect applies as if the item was equipped: that is, Arcstone and Unity ring essences will function properly when applied.
