Unidentified gear
Weapons and armor dropped by monsters arrive unidentified, shown as an Unidentified Sword, Unidentified Armor and so on. You can carry, store, trade and sell them, but you cannot equip, refine, card or rune-socket them until they are identified.
Reveal an item
Use a Magnifier, sold by the Tool Dealers of many towns, including Alberta, Geffen, Morroc, Izlude, Al De Baran and Juno. A list of your unidentified gear opens; choose one item to spend a Magnifier and reveal it, including its rarity and affixes.
Merchants and their classes can cast Item Appraisal to identify an item without a Magnifier. The skill keeps its existing potion and weapon bonuses.
