Starvation

Characters who don’t eat or drink suffer the effects of exhaustion. Exhaustion caused by lack of food or water can’t be removed until the character eats and drinks the full required amount.

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 Constitution modifier (minimum 1). At the end of each day beyond that limit, a character automatically suffers one level of exhaustion.

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