The Horadric Cube is one of the Diablo series’ most iconic items. Introduced in Diablo II, this quest item was an important part of the story and offered a slew of handy transmutation functions, from combining gems to upgrading items. But where did the Cube’s power originate? The Horadrim were vague when it came to the history of this powerful item. Today, we reveal its lineage as the upcoming 2.3.0 feature—Kanai’s Cube.

Lost and Forgotten

The precursor to the well-known Horadric Cube, Kanai’s Cube is a powerful artifact containing immeasurable transmutation power. Originally simply known as “the Cube,” the Horadrim created it as a tool to aid them in the Hunt for the Three.  However, its creation was marred by dark methods and disastrous results, resulting in the order quickly determining that it was too dangerous for anyone to continue using. Creating the weaker Horadric Cube in its stead, they entrusted the first Cube to a secret organization of barbarians on Mount Arreat, who kept it safe from everyone, including the rest of their tribe.

Throughout the years, these barbarians served as guardians over the Cube, keeping it safe from prying eyes and those who would use its powers for evil. The last of these guardians, the great Chief Elder Kanai, perished when the demon lord Baal destroyed Sescheron during the events of Diablo II: Lord of Destruction. The barbarians have always believed their warriors must be put to rest on the slopes of Mount Arreat but, after the destruction of the Worldstone and the mountain that housed it, Kanai’s spirit was unable to rest. Now doomed to stand eternal vigil over his home and greatest treasure, he awaits a powerful and honorable individual to whom he might pass on his task.

One insidious individual has once again found his way amongst the living (sort of) and would love to get his ethereal hands on the artifact his order so foolishly discarded. Of course, he knows only one such individual who might impress the mighty Kanai . . .

Power Untold

So what exactly is Kanai’s Cube going to do for your nephalem hero? The short answer is all the things. This is a huge new feature that will fundamentally change the way you look at an item when it drops. Think of it as the handyman’s (handynephalem’s?) tool for item customization. Not only does it add another layer of character power at your fingertips, but also introduces a structured collection element to the huge item game at the core of Diablo III.

One of the first, most frequent powers you’ll utilize is the ability to extract a Legendary power from an item. This will add the power to your collection list, a comprehensive history detailing the vast amount of powers you’ve amassed. This also allows your hero to equip a Legendary power without having the item equipped, clearing up your stash of all those items you’ve been keeping “just in case.” You’ll be able to equip one power each from three categories:

• Weapons
  • Includes all main hand and off-hand items, including Shields, Mojos, Quivers, and the like
• Armor
  • Virtually everything else; Hands, Legs, Feet, Chest, Belt, Wrists, Shoulders, and Head
• Jewelry
  • Rings and Amulets

Characters may only equip powers from items that their class can normally equip. Powers are also extracted at their most potent value, making it a tough decision between equipping a well-rolled item or melting it down to utilize a maximized power. Powers can be extracted from any level Legendary. Finally, don’t worry if you get tired of a particular ability—you’ll be able to swap freely between the powers you’ve collected at any time by visiting Kanai’s Cube.

Let’s say you’ve hunted down that amazing Legendary that totally makes your build, but it’s rolled less than desirable. If only it had that missing stat, it would have been saved from Haedrig’s anvil. Maybe you regret an enchant you made or you wish that rare Furnace you found was Ancient. With a little effort and a lot of luck, you can rectify these situations. Kanai’s Cube will be able to reforge a Legendary, completely randomizing every roll on the item as though it had dropped brand-new and removing any existing enchants. This includes the chance to roll as Ancient, but be forewarned; if you choose to reforge an Ancient item, there’s no guarantee it will stay Ancient.

There are also several other quality of life functions Kanai’s Cube can perform, such as removing the level requirement from an item, converting gems and crafting materials from one type to another, and converting a set item to a different piece of that set.  We’ll leave you to ponder the best ways to utilize these new features!

Not Just a Legend, But a Tribute

There is more to Kanai’s Cube than lore and functionality. While we always knew that we wanted to implement a form of the Horadric Cube into Diablo III, we never anticipated the events that would lead to it becoming Kanai’s Cube.

Kevin Kanai Griffith was a beloved member of the Blizzard family and a longtime Diablo fan. He joined Blizzard as an artist on the World of Warcraft team in 2005 and his work can be seen in the Burning Crusade, Wrath of the Lich King, and Mists of Pandaria expansions, as well as the World of Warcraft trading card game. As the Diablo III team came together, Kevin joined and made his mark on the original game, crafting a plethora of diverse and moody environments that you’re certain to recognize.

Kevin continued producing gorgeous environments and Diablo holiday art throughout the launch and beyond the release of Reaper of Souls. You might also remember him from footage of his Diableard being shaved live on stage at the 2011 launch of Diablo III, his Artist’s Stage Demo at BlizzCon 2013, or our second anniversary livestream. He was always an active member of the community both inside the company and out, whether it was by organizing weekly sketch groups, or encouraging his friends to team up and play games together. Kevin was an amazing mentor to everyone around him and a wonder to work with: you couldn’t help but get passionate and pumped about your job when he was in the room. 

Tragedy struck in February of 2012 when Kevin was diagnosed with a very rare form of cancer known as Alveolar Soft Part Sarcoma (ASPS). Kevin kept his spirits high throughout the grueling treatment process and continued to work on Diablo III as much as he was able, pioneering environmental features such as the weather and night/day cycles experienced in Adventure Mode. Though he fought valiantly, we lost our coworker and dear friend on October 17, 2014. His spirit and legacy will always live on in the many games he’s touched with his stunning art, as well as the hearts of every individual who had the honor of knowing him.

We miss you, Kevin. This Cube is for you.

Kanai’s Cube Calls…

Kanai’s Cube is a huge feature of Patch 2.3.0, set to change the foundation of Diablo III as we know it. We’re excited to share the intimate background behind this powerful system and in-game dedication to a man who was truly a king amongst mortals.

Which part of Kanai’s Cube has you the most stoked? What kind of Legendary powers are you looking forward to combining the most? Let us know in the comments or, if you haven’t already, hop onto our PTR today and give it a try! We can’t wait to hear your feedback.

Blizzard Quote [source]

The wind blows frozen wisps off snowdrifts, where they’re caught in the decorated grooves of a cold, iron bridge leading to the broken gates of Sescheron. Where once the sights and sounds of a bustling city could be found, now there are only the distant howls of madmen, glimpses of hungry beasts prowling in shadows, and air thick with the palpable weight of shattered hope.

Behold, the Ruins of Sescheron:

The Glory of Past Sescheron

Sescheron was once a living symbol of united Barbarian tribes. Its gates guarded the lone path to Sanctuary’s most precious treasure, the Worldstone, and the Children of Bul-Kathos were tasked with defending those gates. They had done so unerringly for countless generations. It was believed that the city would never fall, and the people of the Northern Steppes would always stand vigilant. In its final days, Sescheron was ruled by Chief Elder Kanai, who was not only loved by the people, but being considered to sit upon the Immortal Throne. Such a high honor had only been bestowed upon two others in the past, including Bul-Kathos himself.

The Day All Hope Was Lost

To this day, all who dare enter the ruins are met with a gruesome reminder—some deeds are so evil that their stains never wash away. . . .         

When Baal, the Lord of Destruction, marched an army of the Burning Hells upon Sescheron, he was met by a lone emissary who denied him passage. Infuriated, Baal took matters into his own hands, and summoned demonic forces to tear the emissary apart. The first blow of the battle had been struck, but more blood would spill before it was over.

Chief Elder Kanai and his people stood their ground against the impossible flood of Baal’s army with every fiber of their being. In the end, however, evil prevailed and the warriors of Sescheron fell. All that was left of the city after Baal’s passage was shattered ruins, the hopeless madness of a failed people, and the cold, empty shadows of a once mighty civilization.

Seek the Ruins and Recover the Cube

The Ruins of Sescheron can be found by opening the Act III Adventure Mode map, and selecting the newly added waypoint in the upper-right corner. Be sure to talk to Zoltun Kulle before you begin your quest to find Kanai’s Cube. A word of advice: Take great care when exploring these dangerous ruins, brave nephalem, for the only thing darker than the suffocating sorrow surrounding these ruins is the shroud of death that hangs over it.

Delsere’s Magnum Opus is the newest Wizard set, added in Patch 2.2.0. Focused on turning the utility-oriented skill Slow Time into a synergistic skill of destruction, many players have found they can integrate aspects of this new set into a Tal Rasha’s Elements build. We’re looking at an equally thematic and effective take on the “DelRasha’s” build today with Corvid#2114’s Bubble Trouble Wizard!

About the Build:

The Delsere’s Magnum Opus set is designed to take a skill normally reserved for utility play and flipping it on its head to bring damage to the table. It’s pretty satisfying to drop a few of these massive bubbles on the map and watch your enemies melt while they shamble hopelessly toward you. The Meteor skill, in and of itself, benefits supremely from the enemy debuffs Slow Time provides and it was only a matter of time before players began to combine Tal Rasha’s Elements and its death from above gameplay with the Delsere’s set. 

Don't burst my bubbles, bro.

While there’s plenty of top end combo builds out there that branch off this style of play, we’re focusing on the more thematic approach that EU player Corvid#2114 sent in. Why stop at Slow Time when you can cover the screen with a variety of bubble-themed skills? 

The Skills:

There’s a major theme in this build and it’s “bubbles everywhere!” Between multiple Slow Time casts and a few other thematic abilities, you’ll be able to keep up a truly bubbly countenance. 

Active Skills:

• Arcane Orb (Frozen Orb)
  • Fits the theme; a “bubble” that you throw
  • Synergizes naturally with the Delsere’s Magnum Opus set, reducing the cooldown of Slow Time
  • Cold element activates one Meteor option of Tal Rasha’s Elements
• Black Hole (Supermassive)
  • Fits the theme; a “bubble” that sucks in and traps your enemies
  • Synergizes well with Slow Time, keeping enemies at bay and frequently locked down
  • Lightning element activates one Meteor option of Tal Rasha’s Elements
• Energy Armor (Force Armor)
  • Fits the theme; this “bubble” protects you at all times
  • Helps combat a Wizard’s inherent squishiness on multiple levels
• Magic Weapon (Force Weapon)
  • Powers up all your abilities, ensuring you’re maximizing your available damage
• Slow Time (Time Warp)
  • The main theme - this is the bubble, and you’ll be casting lots of them!
  • Integral to any Delsere’s Magnum Opus build, offering both damage and utility
  • Stacking either Fire or Arcane bonus damage will activate another Meteor from Tal Rasha’s Elements
• Teleport (Safe Passage)
  • The trusty Wizard go-to for an escape
  • Safe Passage buys you a little more time if things truly turn ugly

Passive Skills:

• Blur
  • Beefs up the build to keep it in the action longer
• Illusionist
  • Helps keep the cooldowns managed on both Teleport and Slow Time
  • Adds a little more mobility to the Wizard by granting you movement speed whenever you’re casting one of these two handy utility spells
• Evocation
  • Reduces all your cooldowns, which is particularly helpful for keeping Black Hole available
• Unstable Anomaly
  • A safety net for when things go awry, granting you a reliable second-life

The Items:

There are a few stiff requirements in this build by virtue of the need to include two sets. However, there’s room for some flexibility with your weapon, ring, and bracer slots to suit your tastes. 

Corvid's still hunting an Ancient Sunkeeper to experiment with in this build. Looking great so far!

Recommended Items:

• Delsere’s Magnum Opus (4-piece bonus)
  • Recommended pieces include Shoulders, Legs, and Boots
  • Turns Slow Time into a sizeable damage dealer
• Tal Rasha’s Elements (6-piece bonus)
  • Recommended pieces include Gloves, Chest, Amulet, Source, and Belt
  • Provides the extra oomph this build needs to progress into higher level Greater Rifts
  • Stacks nicely with Delsere’s Magnum Opus especially when integrating multiple elemental options between Slow Time, Arcane Orb, and Black Hole
• Ring of Royal Grandeur
  • Necessary to acquire the set bonuses from both Delsere’s and Tal Rasha’s

Complementary Items:

• Leoric’s Crown
  • When socketed with a Diamond, provides substantial Cooldown Reduction for skills like Black Hole and Teleport
• Crown of the Primus
  • If you’d prefer to go more Slow Time focused, vastly increases the utility of the skill by providing every rune
  • Great as a more support-oriented option

Recommended Legendary Gems:

• Bane of the Trapped
  • You’ll keep the bonus damage up from this Legendary gem through ample use of your Slow Time ability
• Molten Wildebeest’s Gizzard
  • As all Wizards know, they are super squishy and the Rank 25 shielding ability from this gem helps keep you in the action
• Bane of the Powerful
  • Clear times are pretty quick from pack to pack, allowing you to capitalize on this gem’s benefit

Recommended Stats:

• Cooldown Reduction should be a priority, as you’ll rely on Teleport and Black Hole to keep you out of danger and enemies at bay
• Due to the nature of Delsere’s Magnum Opus, pick one +% Elemental Damage and stick with it; this changes what type of damage your Slow Time will do. Corvid prefers stacking +% Fire damage as a way to proc the Fire Meteor from Tal Rasha’s Elements
• Armor should be your primary Toughness stat to stack, as it complements Intelligence users well and you’ll want to combat your inherent squishiness

Why We Like This Build:

The combination play between these two sets just works, which is why it’s become such a popular build amongst Wizards. What we really dig about Corvid’s build, though, is the extra step taken to combine skills thematically. One realizes pretty quickly how literally well-rounded Wizard skills are when you look at all the ways you can incorporate spheres into your play. Corvid does this thoughtfully and effectively, resulting in a fun iteration on a popular build with room to refine. 

It's hard to be witty about this one — let's just appreciate how great a screenshot this is.

Tell Us What You Think!

How many of you out there run a variation of “DelRasha’s?” Does Corvid’s Bubble Trouble build come close to your take? What tweaks would you make to this build to improve it? We’d love to know in the comments section, so join us and share your thoughts or send your own build in here!

Next week, we’ll brood over a new build with the Demon Hunter. See you then!

PATCH FEATURES

New Feature: The Ruins of Sescheron
The frozen wasteland that is the Ruins of Sescheron are now open for exploration! Filled with new enemies, traps, and environmental hazards, you'll be able to explore the region and learn more about what befell the barbarians of Mount Arreat. Explore the Immortal Throne and obtain the ultimate treasure: Kanai's Cube.

To learn more about The Ruins of Sescheron, click here.

New Feature: Kanai's Cube
Kanai's Cube is a new artisan that offers a slew of new recipes to fully customize your items and catalogue your Legendary powers. Several recipes are available to players immediately upon acquiring Kanai's Cube:

• Extract Legendary Power: Destroy an item to add its Legendary power to your catalogue of collected powers. Once a power has been extracted, it can be equipped to your character without the need to equip the item. Players may have one Weapon, one Armor, and one Jewelry power equipped at a time. Players may only equip powers from items that their characters can normally equip and use.
• Reforge a Legendary Item: Completely re-rolls a Legendary item as though it had dropped for the first time. This includes any powers that may have been previously enchanted on the item. Note that reforged items may re-roll as either Ancient or non-Ancient, so reforge at your own discretion!
• Upgrade Rare Item: Upgrades the quality of a level 70 Rare item to Legendary. This item will roll as a randomized Legendary that shares that item's equipment type.
• Convert Set Item: Converts a Set item to a randomized piece of gear from the same Set. For example, if you convert a pair of Asheara's Finders, you could get Asheara's Custodian, Asheara's Pace, or Asheara's Ward in return.
• Remove Level Requirement: Removes the level requirement from an item, allowing it to be equipped by a character of any level.
• Convert Gems: Converts 9 of any color gem to 9 of any other color.
• Convert Crafting Materials: Converts 100 of normal, magic, or rare Crafting Materials to 100 of another type of non-legendary Crafting Material

To acquire Kanai's Cube, visit Zoltun Kulle in New Tristram, Hidden Camp, Bastion's Keep Stronghold, or The Survivor's Enclave in Adventure Mode. He'll be quite pleased to guide you on your way.

New Feature: Season Journey
Each player approaches a new Season a little differently and we wanted to celebrate individual player successes. Beginning in Season 4, you'll be able to track your personal progress through the Season Journey interface.

A player's Season Journey is divided into chapters, each with their own descriptive goals and achievements. The further you advance in your Season Journey, the more difficult the milestones become and you'll find there are challenges for every level of player. Completing the highest level Tiers will unlock new portrait frame rewards to celebrate your accomplishments.

This feature will be available for testing once Season 4 begins on the PTR. To learn more about Season Journey, click here.

Blizzard Quote [source]

Patch 2.3.0 is currently in development and now available for testing on the PTR. To learn about major changes included in 2.3.0, please see the official PTR patch notes. For information on how to participate, copy over characters, and provide feedback, read on below!

• How to Participate
• PTR Character Copy
• Feedback and Bug Reporting

Further details on how to access the PTR and use the Character Copy system can be found in the FAQ.

HOW TO PARTICIPATE:

To participate in the public test, you must have a Diablo III game license attached your Battle.net account in good standing (i.e. it hasn't been suspended or banned). In addition, you will also need to download and install the Battle.net desktop app if you have not already done so.

Step 1: Create a PTR account. To create a PTR account,  log in to Battle.net Account Management and double-click on your Diablo III game license; this will bring you to the game management page. On this page, click "Create a PTR account." 

If you've participated in any previous Diablo III PTR (including the Reaper of Souls beta), the "Create PTR account" button may not appear. This is because you've already created a PTR account and can therefore skip this step.

Step 2: Once you have created a PTR account, installed the Battle.net desktop, and logged in with your Battle.net credentials, select "Diablo III" from the main menu on the left-hand side of the application.

Step 3: On the Diablo III screen, there is a drop-down menu right above the "Play" button (note that this may say "Install" if you do not have Diablo III currently installed). Select "PTR: Diablo III" from this drop-down menu before proceeding.

Step 4: You should now have the option to install and play the patch 2.3.0 PTR.

The 2.3.0 PTR is available in all supported languages, and accounts from all regions are eligible to participate.

PTR CHARACTER COPY:

The option to copy your existing Diablo III characters from your live account to the PTR will be available and can be done directly through the PTR client. However, only one region per account can be copied at a time. So, if you choose to copy characters from your account in a different region, any previously copied PTR characters will be lost.

Step 1: Log into the live game and then log out.

Step 2: Log into PTR client and create a level 1 character. After you're done, return to the main character screen.

Step 3: Click on the "PTR Copy" button located in the upper right-hand corner. (The PTR Copy button will not appear in-game until you have created a new level 1 character.)

Step 4: Select your region.

Step 5: Click "Copy." This will copy all characters on your account from the selected region.

Step 6: You will be disconnected from the PTR client.

Step 7: Log back in. Your copied characters will be available for play.

Please note that you can only copy characters from one gameplay region at a time. If you choose to copy characters from a different region, any previously copied PTR characters will be lost. In addition, you can only copy characters over to your PTR account once every 24 hours. Attempting to copy characters before this cooldown is up will result in an error.

As a reminder: Any progress made on the PTR will not transfer over to your live account. 

FEEDBACK AND BUG REPORTING:

Once you've had the chance to try things out, be sure to visit the Public Test forums to discuss the patch.

• To provide feedback about content changes in 2.3.0, visit the PTR Feedback forum.
• To report any in-game bugs you find while playing on the PTR, visit the PTR Bug Report forum.

As this is a test server, please anticipate uneven game performance, and note that restarts and downtime may occur without warning.
