Whether you're a ladder competitor or a returning adventurer, mastering the Cube's core recipes is essential for maximizing efficiency and character power.

 

This guide covers gems, runes, rejuvenation potions, socketing, and transmutation formulas—including upgrades introduced in version 1.10 and later.

 

Gem Upgrading Recipes

All gem types (including skulls) can be upgraded through the cube by combining three of the same quality:

3 Health Potions + 3 Mana Potions + 1 Normal Quality Gem → 1 Full Rejuvenation Potion

3 Partial Rejuvenation Potions → 1 Full Rejuvenation Potion

 

Runeword Preparation & Socket Recipes

Remove Socketed Items

1 Hel Rune + 1 Scroll of Town Portal + Any Socketed Item → Same item with empty sockets

 

Removes the jewels, gems, or runes from the sockets in an item. The items in the sockets are destroyed, and all bonuses granted by those items are removed.

 

Fix Low Quality Items (ilvl = 1, ilvl = item level)

1 Eld Rune + 1 Chipped Gem + Low-Quality Weapon → Normal Quality Weapon

1 El Rune + 1 Chipped Gem + Low-Quality Armor → Normal Quality Armor

 

This recipe is useful to upgrade a low quality weapon or armor to normal quality. It can then be used in other recipes to add sockets, in preparation for turning it into a runeword. Any sockets and items in those sockets will be lost after using this recipe.

 

Add Sockets to Normal Items

⚠ The game rolls up to 6 sockets, capped by item limits. Below recipes add 1-6 sockets to the items, making it potentially useful for a runeword.

 

1 Tal Rune + 1 Thul Rune + 1 Perfect Topaz + Normal Body Armor → Socketed Body Armor of same type (1–4 Sockets)

 

1 Ral Rune + 1 Amn Rune + 1 Perfect Amethyst + Normal Weapon → Socketed Weapon of same type (1–6 Sockets)

 

1 Ral Rune + 1 Thul Rune + 1 Perfect Sapphire + Normal Helm → Socketed Helm of same type (1–3 Sockets)

 

1 Tal Rune + 1 Amn Rune + 1 Perfect Ruby + Normal Shield → Socketed Shield of same type (1–4 Sockets)

 

Socket roll chances follow a 1/6, 1/6, 4/6 rule where applicable, depending on max socket capacity.
