I've heard alot of garbage on how to socket items but never any confirmed stuff. Decard Cain says 6 gems to make a socket item from a normal, that probably works but what about rares? I've heard anything from 3 soj's to 1 perfect, to 5 perfects and a soj, and 3 perfects and 2 soj's. So... obviously I'm a little confused. What is the right combination to make a socketed rare/unique?
