couple of questions hi...does anybody know the benifits of upgrading items..eg armour/bows to the next level in the cube. from what i have read and understood, is that the propeties of the item stay the same. also i am using tal rasha's mask which i have socketed with a jewel...but...i have found another better jewel. if i use my hel rune to unsocket the item..do i just loose the jewel or will the socket disappear too. thx.
