I'm nearing the end of Act 1, so maybe it's less usefull in the later acts, but Pickpocket has made me a wealthy Death Knight. Well I gave it to him since he's already evil <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" />. Anyways if you have never tried it you can practically empty the merchants and citadel guards of anything. You can only have 3 or so picks but it's not limited by item quantity so I 'found' so many bundles of expensive arrows I don't know what to do with them. I have thousands, and the splitter arrows are worth 128 gold EACH.
On the other hand the Embellish skill appears worthless since each valuable skillpoint only increases item value by about 3 percent.
