Frequently Asked Questions
What is the Horadric Cube?
The Horadric Cube is a 3×4 grid item found in Act 2's Halls of the Dead. It acts as a portable crafting station — place the right combination of items inside and click Transmute to create something new. It holds 12 items but only takes up 2×2 space in your inventory.
Do I need all ingredients exactly as listed?
Yes, most recipes require exact ingredients. Some recipes accept a category (e.g., 'any Normal Weapon') but the gem and rune requirements are exact. The Belt crafting recipe famously requires the specific item called 'Belt' (the 12-slot one), not any belt-type item.
What's the best use of Perfect Gems?
Perfect Gems are used for crafting recipes (and for rerolling magic items like Grand Charms). No rune upgrade uses Perfect gems — high-rune upgrades use regular gems (Um through Lo) or Flawless gems (Lo through Zod). For most players, the best use is: Perfect Rubies → Blood Gloves crafts, Perfect Amethysts → Caster Amulet crafts, Perfect Sapphires → Hitpower crafts, Perfect Emeralds → Safety crafts.
Why is clvl 93 important for crafting?
At clvl 93, every gambled amulet has ilvl ≥ 88. The crafted ilvl formula (int(93/2) + int(88/2) = 90) means every craft has alvl 90, which is the minimum required to roll +2 Class Skills on an amulet. Below clvl 93, some gambled amulets will be too low ilvl to ever roll +2 skills.
Can I get my gems and runes back after unsocketing?
No. The Hel + Scroll of Town Portal + Socketed Item recipe destroys all socketed items permanently. The base item is preserved with empty sockets, but the gems, runes, and jewels inside are gone. Plan carefully before unsocketing.
What's the most efficient way to upgrade runes?
For runes up to Pul (rune #21), you need 3 of the previous rune — this scales exponentially (one Pul is 3^20, or roughly 3.5 billion El runes, which is why nobody cubes from scratch). For Um and above, you need 2 runes + a specific gem. Gem quality steps up with the tier: a Flawed Diamond to make Um, regular gems for Mal through Lo, then Flawless gems for Sur through Zod (e.g. 2x Lo + Flawless Topaz = Sur). No rune upgrade ever needs a Perfect gem.
