heck if they just gave it the ability to counter act cold that'd balance it out without making it broken. not like the wolf armor does, but just the general level of cold from night. so say you went into the mountains, without fire you'd still be freezing.

likewise, eyescream could give a hot area debuff removal. i think we all know the ashlands will eventually have a Hot Debuff for the land area, overcome by being wet or potion buff. untill you can get gear made from the molten rocks there.
