I see a lot of questions popping up about Kanai's Cube since its release, so I am hoping to be able to put together a list of common questions, along with helpful information regarding the cube.
- What is Kanai's Cube? Kanai's Cube was introduced in Patch 2.3, and is the spiritual successor to Diablo 2's Horadric Cube.
- What can the cube do? All sorts of stuff, from extracting legendary powers to upgrading rares into legendaries. I will get into the specifics of each recipe later, but for now just realize that the cube is a powerful tool.
- Does the cube take up stash space? No, the cube is now part of the town center along with the other artisans (blacksmith, jeweler, etc.).
- Where do I find the Cube? The cube is in a new area of Act 3. In order to obtain the item you must make your way through the first floor of the "Ruins of Sescheron", and finally get to the second zone called the "Elder Sanctum". In this second zone you will find the "Tomb of King Kanai", at which point a small scripted event takes place and you will have the cube and its artisan unlocked in town.
- The cube is available to both Season and Non-Season players.
- While it has not been confirmed how the transition will occur at
the end of Season 4, it is reasonably safe to assume that the stored
cube powers will be handled much in the same way that artisan
levels/plans are - once the season ends it automatically rolls over to
your non-season gear.
edit: It has been confirmed that the extracted powers will roll over to non-season as other artisans's are. source
- When putting in a stack of items, the cube is smart enough to only use what it needs. If a recipe calls for (5) Death's Breath, and you place a stack of (50), you will have (45) back in your inventory when you complete the recipe.
- Kanai's Cube is not available to PS3 and XBox360 console users.
Extracting Legendary Powers - an in-depth look.
- So the first recipe everyone loves about the cube is the "Archive of Tal Rasha". This recipe allows you to extract a legendary power from an item, in turn destroying the item itself. In order to do this, you must have (1) of each of the new Legendary Crafting Mats (each act gives a new material in their bounty cache's, (1) Legendary item with a Legendary Affix you wish to remove, and (5) Death's Breath.
- You are allowed to have an active Weapon Slot, Armor Slot, and Jewelry Slot. Weapons include all items that are equipped in your hands (weapons, off-hands, and shields). Armor includes all armor, so you can choose one item from Helmet, Shoulders, Gloves, Pants, Boots, Belt, Chest, and Bracers. Jewelry includes Amulets and Rings, so you must choose between a 3rd ring or 2nd amulet essentially.
- Note that this only applies to legendaries, and you cannot extract a set item in lieu of equipping said item. Example: you cannot extract Zuni's Pants in the hopes that you would no longer have to equip them to get the set bonus. For further clarification, set items that have legendary affixes such as Krelm's Belt can have their legendary affix extracted...but you cannot gain the benefit of the set. So if you use the belt's power in the cube, and equip the bracers, you do not get the set bonus.
- Now, lets say you want to extract the legendary power from The Furnace which is "Increases Damage Against Elites by 40-50%". The first thing to know is that no matter the value of the item you put in, the power extracted will always be at its max. So if your Furnace only rolled 40% elite damage, the ability will extract at 50%. Ok, so as stated above, place your Furnace, (1) each of the legendary act specific mats, and (5) deaths breaths in the cube and hit "Transmute". You will get a warning that you are about to destroy your item, that's ok - hit "OK".
- Now that the Furnace's power has been extracted, you need to "equip" it. Within the cube GUI, click the icon marked with a sword (you can see it here). This opens up a book of all the available items you can extract, so rifle through the pages and select The Furnace. Once you have, the image of the sword you clicked on will now show the image of The Furnace. If you want to verify that a specific power is activated, you can open up the details screen in your inventory and scroll to the bottom - it will now show any active attributes coming from Kanai's Cube.
- There are some items that cannot have their legendary power extracted such as The Corrupted Ashbringer, The Hellfire Amulet, and Ancestors Grace.
- Also of note, you cannot utilize two of the same power. In the example of The Furnace, if you have one equipped on your character, and select The Furnace in your cube, you will not get 2x bonus.
- Extracted powers work from any legendary item at any level. So if you find a Starmetal Kukri at level 45, it is no longer useless. Save it, and you can extract that very awesome power once you have the cube and the mats.
- Extracting the Ring of Royal Grandeur is the same as wearing one (again you can't wear one and have one in the cube). This opens up great gearing options for the 2x ring slots you now have.
- Extracted powers are only available to characters that could normally utilize the original item. A barbarian could not use a power from a monk daibo.
- Lastly, once you have extracted a power it is now available to all characters you have. If your WD extracted The Furnace in the above example, your Monk could equip that passive as well.
Reforging Legendary Items
- The next recipe is called "The Law of Kulle", it allows you to reroll the stats on a legendary item - with the added bonus that the reroll can result in an Ancient Legendary. The odds to reroll Ancient are 1/10.
- The "Law of Kulle" recipe is (1) legendary item, (5) each legendary act crafting material, and (50) forgotten souls.
- Place all of the items in your cube, hit transmute, and you will get a "new" version of the item you had in there.
- Keep in mind that if you use a Ramaladni's Gift on an item, then use this recipe, the socket you gifted is now gone.
- This recipe merely rerolls the item, it does not upgrade it. Meaning that you cannot expect to reroll a lower level legendary to get a level 70 version.
- Rerolling a legendary is "smart", in that if you have a Strength In-Geom and reroll it on a Witch Doctor, it will roll with Intelligence. thanks /u/rcuhljr
Upgrade Rare Item
- This is the second best thing about the cube in my opinion. This recipe allows you to take a rare item, and turn it into a legendary (with a 1/10 chance of it being an Ancient Legendary).
- The "Hope of Cain" recipe is (1) level 70 rare item, (25) Death's Breath, (50) each normal crafting material (reusable parts, arcane dusts, veiled crystal).
- Place all of the above items in your cube, hit transmute, and watch that rare transform into a legendary!
- Great uses for this are on weapons, jewelry, and Templar relics. Early in Season 4 I was able to turn a bunch of Rare Ceremonial Knives I had picked up off the ground into an Ancient Dagger of Darts (I equipped this), and also a Starmetal Kukri (I extracted this power). I was also able to craft a bunch of Templar relics and then upgrade them, finally getting the "cannot die" relic I wanted.
- The rare item that goes into the cube can be purchased from a vendor, found in monster loot, or crafted at the blacksmith.
Converting a Set Item
- We have all had this issue - you have 5/6 of a set and the drops you get keep giving you gloves and not the damn item you NEED. The "Skill of Nilfur" recipe allows you to take a set item and convert it to a different item from that set. Keep getting Zuni's gloves and not boots? Use this recipe to convert that glove into another item from the set. Note This only works on sets of 3 or more pieces, and cannot produce an Ancient Set item.
- The recipe is (1) Set Item, (10) Death's Breath, and (10) Forgotten Souls. Place these in your cube, hit transmute, and pray that the RNGod's are smiling upon you.
- Example of how this works: You need Zunimassa's Boots, and you have an extra pair of Zunimassa's gloves. Place the extra set of gloves, along with (10) each Death's Breath and Forgotten Souls into the cube, hit transmute. If you get the boots, GREAT, if not just load another (10) materials and transmute again.
Removing Level Requirement
- While not that great for softcore players, this could be a great benefit to Hardcore players. The "Work of Cathan" recipe allows you to remove the level requirement of any gear item by transmuting (1) item of any type, and (1) rank 25 or higher Gem of Ease.
- This will consume the Gem of Ease.
Converting Gem Types
- Running out of Topaz's? You can now cube all those useless Rubies using the "Darkness of Radament" recipe. This recipe is capped at 9 gems per "roll", and requires a Gem Essence (sold by Squirt in A2).
- The recipe is (9) Gems of the same type/quality, and (1) Gem Essence (of the type of gem you want). Hit transmute and voila, you have a new stack of gems.
- An example: You have 1000 Imperial Amethyst's, but really need more Emeralds. Go to Act 2 and purchase the Emerald Gem Essence from Squirt. Throw in your cube the amethysts, and the essence - hit transmute and receive your Imperial Emeralds.
- Gem Essence costs 500,000 gold.
Converting Crafting Materials
- Similar to the gem conversion, this one really helps with collecting specific materials. I know in previous seasons I could never have enough blue/white mats while I would be swimming in yellows. The "Anger of Iben Fahd" recipe now invalidates this issue.
- The recipe is (100) crafting materials (either white, blue, or yellow), (1) item of the material quality you want to receive, and (1) Death's Breath.
- An example: I need more Arcane Dusts (blue), and have a TON of Veiled Crystals (yellow). I would put (100) veiled crystals, (1) blue item (sword as an example), and (1) Death's Breath into the cube. Hit transmute and receive (100) Arcane Dust. note: the item you use in the cube can be crafted, purchased, or found while playing.
Two, Not-So-Secret, Secret Recipes
- Portal to "Not the Cow Level". Simply put a Bovine Bardiche into the cube, hit transmute, and open a portal to the "Not the Cow Level".
You can only open one Cow Portal per game. If you see the portal open in town, you have to remake the game in order to get a new portal open. Trying the recipe when there is already a portal open will result in a "failed to transmute" message.
- Portal to Greed's Realm Another simple recipe. Put a Puzzle Ring into the cube, hit transmute, and open a portal to "Greed's Realm".
You can only open one Greed's Realm Portal per game. If you see the portal open in town, you have to remake the game in order to get a new portal open. Trying the recipe when there is already a portal open will result in a "failed to transmute" message.
Act Specific Legendary Materials
- Bounties have been changed a bit in patch 2.3. The major change is the rotating "bonus" act and how it effects material drops.
- When you start a new game in adventure mode, you will notice on the map that one of the acts is now labeled "Bonus". If you complete all the bounties in this act, before any other act, you will receive a second "bonus" cache along with the standard cache. Once this is done, the bonus act randomly changes to a different act.
- It is now beneficial to run all 5 acts in the sequence the game chooses the "bonus" acts to maximize the amount of materials you earn
- The bonus cache can also drop a legendary item.
- Blood Shards are no longer awarded for completing the individual bounty, rather they are only given in the bonus cache.
- Horadric Caches will now contain two legendary/set crafting recipes. This is a great way to fill out your artisans quickly at the start of a season.
- There are five act specific legendary crafting materials. These are required for legendary/set crafting at the blacksmith, as well as for many of the Kanai's Cube recipes.
Act 1 - Khanduran Rune
Act 2 - Caldeum Nightshade
Act 3 - Arreat War Tapestry
Act 4 - Corrupted Angel Flesh
Act 5 - Westmarch Holy Water
- Here is a great chart showing all the Torment Scaling information for 2.3. Important to note the legendary crafting drop rates (doubled for bonus cache) are:
Normal-Master: 2 (4)
T1-T6: 3 (6)
T7-T10: 4 (8)
