I just trained my priest in arcane lore, but i dont know how to use it or get it to work. When i click on my special traits button, it wont scroll to that trait, help!

arcane lore is used with ARTIFACTS - and will allow you to identify items.
To identify an item, click on it in the inventory and in the new window there will be a question mark icon - click on that and if possible your magic user will identify the item. The more special the item, the higher your skill must be to be able to identify the item.
