Frost Resist Gear

I've been doing a little bit of reading about Naxx. Just to figure out the bosses and such. And it looks like there is no resist gear needed, except for the second to last boss, Sapphiron. He needs a bunch of frost resist gear.

The cloth resist gear is the Glacial Robe, Glacial Slippers, and Glacial Waistband. And the mail resist gear is Icy Scale Chestguard, Icy Scale Boots, and Icy Scale Belt.

Each of these sets will give a total of 287 frost resist, if not gemmed for frost resist. Since, at 80, you only need 415 resistance to be capped against a mob 3 levels above you, which is the level of bosses, the missing 128 resist can be made up by Shaman totem or Pally aura.

There is also a Titanium Frostguard Ring, which can add another 68 frost resist, if some more mixing and matching is desired.

And even though there is an achievement for doing the Sapphiron fight with less than 100 frost resist on each person I think that will come a while after the boss has been killed with frost resist a couple of times. So I'll start looking in to the mats for these and seeing how expensive it is to buy the mats and find a crafter as opposed to just buying the gear off the AH.
