Hello, don't know if the following is self-evident and everyone do so, but I found out, when you identify your clean items the price for them grows a bit. Example: I found a warhammer. The trader would give 50 gold to me. After identifying the hammer he gives 75g to me. So: 1 Identify costs 5g --> 20g more profit. In 9 from 10 cases you get more gold after irdentifying your items.
