The Identifier is a Villager NPC located throughout the Wynn Province and Gavel Province. The Identifier is used to identify Unique, Rare, Set, Legendary, or in rare instances Mythic Items. Identifications are attributes added to Weapons, Armour, and Accessories to make it do more damage, regenerate health and mana, or other features. Items can gain powerful abilities when Identified. Identifiers can be found along the Emerald Trail, and in several of Wynncraft's large towns.
To identify first you must right click the identifier NPC. A menu with 9 slots with a checkmark at the end and your inventory should appear. In your inventory, click the equipment you wish to identify to place it in the slots. If you have a sufficient amount of Emeralds and Emerald Blocks in your inventory to identify the item(s), the checkmark should be green. If it is red, you aren't carrying enough emeralds and you may scroll over it to reveal how many you need. When the checkmark is green, you may click it to begin the identification process. The equipment in the identification slots will then quickly cycle through different items until it has been identified, and then you can put the equipment back in your inventory.
Notes
Some items that have a lower identification limit usually have higher bonuses than other items near its level. (Treasure Boots, for example, can only be identified once, but gives very high loot bonus).
On the path from Ragni, heading east towards Detlas, the Item Identifier's hut is on the right of the path, just past a watchtower, before you reach Nivla Woods.
In the southeast corner atop the city, the Item Identifier is inside the tree area immediately left of the entrance to a building called Llevigar University.
