Thanks a lot for explaining, i've finally figured out how trade works. But when it comes to the repairing im still having trouble. When i select the repair skill and right clik it, cursor turns into a little hammer as you said, but when i click on one of my items that has been decrased in terms of durability, it just doesn't repair. It uses mana, but the item's durability does not chance. I'm a doing something wrong or might that mechanic be broken in my current save by any chance?
