Frost Resist Gear Stats and Materials

[MongoJerry]

Frozen Runes have to be looted off the walls of Naxx. Some can be found in the Anub'Rekhan room.

However, you need to learn 'Word of Thawing' to do so. It's a trash drop.

Are they tradeable at least or are they bind on pickup?

I agree with Monkey that having Frostwhisper drop one would be cool.
