I personally prefer to socket the orb with Ist, and the helm + armor with Um runes or PTopaz, I try to max my resists with small life charms + resists.

Some people prefer to put facets in but i prefer a mf + survivability build haha

full tals blizz sorc with moser's shield 2x pdiamond, dwarf/bk/soj depending on what you want to spend and a raven so you can't be frozen. chancies and war travs. that's all you need to mf with. insight merc to start and upgrade to infin when price of ber drops to where you want to spend.

It's hard to get tal set without fg in the first place
