Survival allows a character to find food, water, or shelter in hostile environments. A character may only make one roll per day. A successful roll finds sustenance for one person, a raise on the roll finds food and water for five adults. Horses and other large beasts count as two adults. Children, camels or others with small appetites count as half. Those who benefit from the roll do not have to make Fatigue rolls for the day for food, water, or shelter.
