Against the Ice
In polar environments, frostbite is a serious concern. Polar Survival allows you to protect yourself and others from this hazard.
A 1 point spend from your Outdoorsman pool will protect two people from frostbite for one day of activity in very cold climates. These people (obviously one of these should include yourself) must stay with you through the day, occassionally being checked or coach to avoid hazards.
Additionally, you can deal with the hazards of travel, food preparation and building structures in arctic environments.
