Nov 6th 2008 3:48PM RNG, Don't fail me now.
Oct 30th 2008 5:25PM It adds a colorless socket to the item. It doesn't give a socket bonus or affect the socket bonus of the item at all.
Oct 19th 2008 9:29PM Azshara is powerful, but it is never really shown how powerful. At the end of War of the Ancients, she hold off the Well of Eternity for a good bit, so she is powerful, but we are not given anyway to measure it. She is also given power from the Old Gods. So I am pretty sure she is at least as strong as Kil'jaeden.
