I simply can't see how to do this and it's frustrating me beyond all reason, Google searches are no help either. Obviously I'm missing something but for the life of me I can't fathom what. For example, I go to my Blacksmith and ask to Upgrade my gear. I can select any of the items I am cuirrently equipped with and I see the current state and a preview of the upgraded stae. If there is a rune slot available I see that too. But I can find no way of interacting with the rune slot. If on the other hand I try my Inventory, I can make no progress either. What on earth must I do? I really would appreciate help here. It's driving me crazy!
