- Items of "Enchanted" (green) quality and lower never require identification.
- Rare (blue) items are unidentified if the item's level is higher than your current level. Upon leveling up, any blue items equal to your level will automatically be identified. You can still identify it ahead of time.
- Note that an item's level is not necessarily the same as the character level required to equip it. So in some cases identifying a blue item may allow you to equip it immediately, while in others you may not yet meet the equip requirement.
- Unique (gold) items always require identification.
Items are still identified using scrolls, though Identify Scrolls are less common, since they are needed less often. You can buy it from the merchant too.
