1.08 shako with ber
Oculus with resist/life jewel
Armageddon Fletch
1.08 Valor with ber
SS with ber
if USEast, use Grim Spur boots for the fhr, resists, and stats
Magefist because you will need at least 70% fast cast, (30 oculus, 20 amulet, 20 gloves)
10x Cold skill charms with +life, do not use lightning charms because lightning damage is easily countered whereas the cold charms increase your mastery and everyone knows orb does a ton more damage

For a switch vs. other sorcs, use absorb gear and as much stacked resist as you can get to negate cold mastery.

For your merc use a .08 Windforce with ohm (IAS is not needed on a merc as it shoots each time you teleport, which is faster anyways). For its helmet use a blackhorns for the slow target and lightning absorb. Armor, use Vipermagi if there are a lot of other sorcs for the resists, or use .08 valor if not. Damage reduce doesn't work on a merc so there's no need for a shaft or whatever else.

The 10 small charms you'll have room for should all be 15+life and mana (both) on each charm. You have 50% fhr with the above gear so you don't need any more of it unless you go for the next breakpoint which takes a TON more and isn't worth trying for.
