Recipe: Random Magic Item of Same Type – Diablo 2: Reign of the Warlock

Horadric Cube recipe for Random Magic Item of Same Type.

Inputs

1x Same item type (magic)

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 level of the input item.
If you're cubing for +skills Grand Charms, for instance, you want to use Charms starting from late Nightmare, and not ones that dropped in Normal Blood Moor.
Be warned, still, that the chances of getting that on an Amulet is very low (considering everything that's available), and it might take many tries.
Rare items cannot be used with this formula to create new Rare items.

Not to be confused with: Recipe: Socketed Magic Weapon ilvl 25 Recipe: Socketed Magic Weapon ilvl 30 Recipe: Socketed Magic Weapon of Same Type The above recipes cannot be used to reroll charms or jewels.
To add sockets to a magic weapon and re-roll mods use these: Recipe: Socketed Magic Weapon ilvl 25 Recipe: Socketed Magic Weapon ilvl 30.
As long as the zone is not terrorized, all Grand Charms dropped in these zones will be between ilvl 50-54, meaning they meet the minimum qualification for a +1 Skills prefix but do not yet meet the requirement for the next obtainable prefix ("Lucky" - 8-12%), which can be obtained starting at ilvl 55.
The best place to get Grand charms to reroll is Terror Zones with your character level 90.
Any three Perfect Gems, including Perfect Skulls, work; consider saving Perfect Amethysts and Rubies for crafting recipes.
