With the system update, our beloved smithing iron daggers technique has been severly nerfed. not that i argue, it was kinda cheap, but it made smithing way easier. But now smithing leveling is based on the value of the item. I found that going to Kolskeggr mine, while providing a very entertaining battle with the forsworn, you can mine plenty of gold ore and also silver at karthwastern. along with gems and jewels we can make jewelry worth up to 1200 gold and about one whole smithing level if you are below level 50.
