Food and Water

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.

Food

A character needs a certain amount of food per day to feel satiated. The amount of food a creature needs is determined by their size as listed in the Daily Food Requirements Table. A creature can make food last longer by subsisting on half rations. Eating half of your daily required amount of food in a day counts as half a day without food.

Daily Food Requirements

Starvation

A creature can go without food for a limited number of days before starvation sets in, this is called their starvation limit. A character's starvation limit is equal to 2 + their Constitution modifier (minimum 1). At the end of each day beyond that limit, the character suffers one level of exhaustion .

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

Water

The amount of water a creature needs each day is also determined by their size and is listed in the Water Requirement Table. A creature needs to drink double their required water each day if the weather is hot.

Daily Water Requirements

Dehydration

A creature can go without water for 24 hours, or half that amount of time if the weather is hot. After 24 hours without water, the creature begins feeling severe thirst. A creature can function normally for a limited amount of time while severely thirsty before they suffer the effects of dehydration, this is called their dehydration limit. A character's dehydration limit is a number of hours equal to four times their Constitution modifier (minimum of 1 hour). After every hour without water beyond their dehydration limit, the character gains a level of exhaustion at the end of the hour.

A normal day's worth of water consumption resets the count of hours without water.
