Besides the obvious use of unraveling, is it even worth going through the magic items found in a treasure chest? I've gone through several dozen and never found a single item that was maybe possibly worth keeping. Do the items become better quality at the higher level of the chest? Are there certain qualities of items that I should be keeping an eye out? I have a pretty rough idea what to look for in Shame but I'm at a complete loss when it comes to treasure hunting. Thanks!
