Considering that it would work against cold-based attacks like a Cone of Cold, it will protect you from damage from spells or attacks using that energy type. I will have to ponder if it would also protect you from more persistent cold effects like you will be dealing with in the Antarctic. It probably will, but I want to think it over.Sherwood In your Palladium Rifts game, is cold counted as a form of energy (specifically in regards to the Impervious to Energy spell)? =)
