What it does

Lifts the item one rarity, up to Legendary. Every modifier stays, the base bonus becomes the new rarity's and the item gets 1 more.

Only an item with a rarity below Legendary. It never makes Divine; unique items are refused.

Uniques, ruined and corrupted items and stacks are refused; the crafting bench shows what an orb would do before you use it.

Used directly: Use with on the orb, then click the item.
