Food and Water
Characters who don’t eat or drink suffer the status effects of Maimed stacks, and are Exhausted. Maimed caused by lack of food or water can’t be removed until the character eats and drinks the full required amount.

Food
A character needs one pound of food per day and can make food last longer by subsisting on half rations. Eating half a pound of food in a day counts as half a day without food. A character can go without food for a number of days equal to 3 + his or her Body (minimum 1). At the end of each day beyond that limit, a character automatically suffers one stack of Maimed, and is also Exhausted.

A normal day of eating resets the count of days without food to zero.

Water
A character needs one gallon of water per day, or two gallons per day if the weather is hot. A character who drinks only half that much water must succeed on a DC 15 Fortitude or suffer one stack of Maimed at the end of the day. A character with access to even less water automatically suffers one stack of Maimed at the end of the day, and becomes Exhausted.
