Horadric Cube

"The Horadric Cube is quite a treasure. It took many years of research and study to uncover its secrets. And it's also a charming footrest!"

- Deckard Cain

The Horadric Cube is a device of Horadrim design.

Lore
The Horadrim and/or their writings were vague when it came to the origins of the Horadric Cube. However, it is known that the Cube stemmed from a more powerful version. However, the original Cube was marred by dark methods and disastrous results, resulting in the order quickly determining that it was too dangerous for anyone to continue using. The Horadric Cube was then created in its stead.

The Horadric Cube operates via the principles of transmutation and alchemy. The Horadrim preserved important artifacts and equipment by separating them into the component parts for future use. By later utilizing these elements within the cube, they could reassemble the original item.

Long after the time of the Horadrim, the cube was obtained by a group of heroes that pursued the Dark Wanderer. They utilized the cube to meet their goals. Afterwards, Deckard Cain spent years researching the Cube and uncovering its secrets.

In-game
The Cube is used in Diablo II. The Cube's magic allows certain items to be transmuted into other items. For example, a simple recipe would be two quivers of bolts into a quiver of arrows.

The Horadric Cube is found in the Halls of the Dead in, guarded by a monster called. The Cube is also needed to fuse the and the  to make the, as well as fusing Khalim's body parts and  together into.

While most items can be crafted and enchanted by the skilled hands of a worker of the forge, there are those few items which are outside of a mortal's ability to create. The Horadric Cube functions by intimately binding the Prime Energies of the items stored within it. This is a highly specialized process that requires the use of certain items which "resonate" with each other.

It can also contain 12 slots worth of items, while only taking up 4 slots itself. Note that charms do not work while they are inside the cube.

Recipes
You can use the Horadric Cube's magical powers to Transmute items into a new item. Simply place the items into the Cube and click the Transmute button. This includes and the recipes in the following list:

NOTE: ilvl = item level | clvl = character level


 * 3 = 1 Random 


 * 3 = 1 Random 


 * 3 Small Rejuvenation Potions = 1 Full Rejuvenation Potion


 * 3 Gems of the Same Type and Grade (lower than Perfect) = 1 Higher Grade Gem of the Same Type


 * 2 Quivers of Bolts = 1 Quiver of Arrows


 * 2 Quivers of Arrows = 1 Quiver of Bolts


 * 1 + 1 Quiver of Arrows = 1 Stack of s


 * 1 + 1  = Throwing Axe


 * Strangling Gas Potion + any type of Healing Potion = 1 Antidote Potion


 * 3 Runes of the Same Type (Runes 1-9) = 1 Higher Level Rune
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 -> 1
 * 3 + 1 Chipped Topaz -> 1
 * 3 + 1 Chipped Amethyst -> 1
 * 3 + 1 Chipped Sapphire -> 1
 * 3 + 1 Chipped Ruby -> 1
 * The following upgrades will only work on Single-Player, open, or Ladder!
 * 3 + 1 Chipped Emerald -> 1
 * 3 + 1 Chipped Diamond -> 1
 * 3 + 1 Flawed Topaz -> 1
 * 3 + 1 Flawed Amethyst -> 1
 * 3 + 1 Flawed Sapphire -> 1
 * 3 + 1 Flawed Ruby -> 1
 * 3 + 1 Flawed Emerald -> 1
 * 2 + 1 Flawed Diamond -> 1
 * 2 + 1 Topaz ->
 * 2 + 1 Amethyst ->

 * 2 + 1 Flawless Ruby ->
 * 2 + 1 Flawless Emerald ->


 * 3 Perfect Skulls + 1 + Stone of Jordan = Add 1 Socket To a 
 * Rare Items can only have one socket. You cannot add sockets to items which don't normally have sockets. You cannot use this on a Rare which already has one socket, and you can only add one socket to a zero-socket Rare Item.


 * 1 Perfect Skull + 1 + Stone of Jordan = 1 High Quality New  of the same type
 * This formula has the possibility of creating a higher quality Rare Item than the following formula. ilvl = int(.66 * clvl) + int(.66 * ilvl) That is, the ilvl will be equal to .66 times your clvl (rounded down) plus .66 times the input item's ilvl (also rounded down).


 * 6 Perfect Skulls + 1 = 1 Random Low Quality  of the same type
 * You can use this formula to get another chance at a Rare Item of the same type. ilvl = int(.4 * clvl) + int(.4 * ilvl) Player level matters. This formula will not work on items larger than 3x2.


 * 4 Health Potions (of any type) + Ruby (any type) + = A  of the Leech
 * You can use this formula to get a Life Stealing sword. ilvl = 30. The sword will always have the "of the Leech" (4-5% Life Stolen Per Hit) and has a chance at getting a  as well. The type of sword is retained.


 * 3 Perfect Gems (of any type) + 1 = 1 New Random  of the Same Type
 * You can use this formula to get another chance at a Magic Item of the same type. The ilvl = ilvl. This means to use 100% of the ilvl of the input item. It's important to note the difference between "the ilvl is set to a fixed number" like what happens in some recipes and "the ilvl of the output is exactly the same as the ilvl of the input" as is the case here. So if you're cubing for +skills Grand Charms, for example, you want to use Charms starting from late, not ones that dropped in the Blood Moor. You can use this formula (with an Amulet) to create a +2 Skills Amulet. And you cannot Gamble one before Character Level 84. Be warned however, that the chances of getting that on an Amulet might be very low (considering everything is available) and it might take a lot of tries. Rare Items cannot be used with this formula to create new Rare Items. You can also use this on Charms and Jewels.


 * 6 Perfect Gems (1 of each type) + 1 = Prismatic Amulet
 * Use this formula to create an Amulet with Resistance to all. ilvl = 50. The amulet will always have the Prismatic (All Resistances +16-20) and has a chance at getting a  as well.


 * 1 + 1 Perfect Emerald + 1 Antidote Potion = 1 Jade Ring
 * Use this formula to create a Poison Resistance Ring. The Jade Ring has a random percentage (21-30%) of Poison Resistance. You may also receive an additional Magic Suffix. ilvl=30.


 * 1 + 1 Perfect Ruby + 1 Exploding Potion = 1 Garnet Ring
 * Use this formula to create a Fire Resistance Ring. The Garnet Ring has a random percentage (21-30%) of Fire Resistance. You may also receive an additional Magic Suffix. ilvl=30.


 * 1 + 1 Perfect Topaz + 1 Rejuvenation Potion = 1 Coral Ring
 * Use this formula to create a Lightning Resistance Ring. The Coral Ring has a random percentage (21-30%) of Lightning Resistance. You may also receive an additional Magic Suffix. ilvl=30.


 * 1 + 1 Perfect Sapphire + 1 Thawing Potion = 1 Cobalt Ring
 * Use this formula to create a Cold Resistance Ring. The Cobalt Ring has a random percentage (21-30%) of Cold Resistance. You may also receive an additional Magic Suffix. ilvl=30.


 * 1 (any type) + 1  (any quality) + 2 Skulls (any quality) =  of MS Spikes
 * The shield will always have the "of Spikes" (Attacker Takes Damage of 4-6) and has a chance at getting a  as well. The type of shield is retained, and any type of shield (including Paladin Shields and necromancer Shrunken heads) works as input. ilvl=30.


 * Diamond (any quality) + 1 Staff (any type and quality) + 1 Kris (any quality) + 1 Belt (any type and quality) = Savage Polearm Class Weapon
 * The polearm will always have the Savage (66-80% Enhanced Damage) and has a chance at getting a  as well. ilvl=50.


 * Wirt's Leg + A Tome of Town Portal = Secret Cow Level

 * Any grade of health and mana potions can be used.


 * 3 Standard Gems (normal) and 1 Socketed Weapon (Any Type) = 1 Socketed (of same type) 
 * This takes a socketed weapon and makes it a magic socketed weapon with 1-2 sockets. This allows you to get new magic bonuses on an otherwise non-magical weapon. The original weapon properties will be "rerolled" when the new weapon is created. ilvl=30.


 * 3 Chipped Gems + 1 = Socketed 
 * This adds 1-2 sockets to a magic weapon. The original magic weapon properties will be "rerolled" when the new weapon is created. If you use this formula with a weapon that is not normally socketed such as a Javelin, this recipe will create a new magical weapon without any sockets. ilvl=25.

 * Same as previous recipe except ilvl=30.


 * 1 + 1  + 1 Perfect Topaz + Normal Body Armor = Socketed Body Armor of same type
