Armorsmiths who ply their trade in locales known for extreme weather learn ways to adapt their styles to produce armor specially suited for the environment. In hot locales, armorsmiths create well-ventilated suits of armor to prevent overheating, while in cold climates the craftsmen insulate their armor in order to help keep in body heat. A suit of armor with this item quality provides a +2 circumstance bonus on saving throws against harsh environmental conditions in either extreme heat or extreme cold (determined at the time the armor is created). Restriction: May only be applied to armor.
