Identify

To identify means to reveal and "learn" the full properties of an item. Identifying an item will reveal any magical properties it has such as weapon upgrades (for weapons) or runes (for salvage armor) as well as its sell value at merchants.

By identifying a weapon upgrade or rune you unlock it for PvP play.

To identify an item you need either an Identification Kit or a Superior Identification Kit. Items that display their sell value are already identified.
