Deprivation

A Small or Medium creature needs at least one pound (½ kilogram) of food, one gallon (4 liters) of water, and six hours of sleep every day.

Food: At the end of each day, a hungry creature must succeed on an Easy (2+) Strength test or suffer one level of exhaustion. After two weeks of starvation, the target number instead equals the number of weeks since the creature last met its daily need for food.

Water: At the end of each day, a thirsty creature must succeed on an Easy (2+) Strength test or suffer one level of exhaustion. After two days of dehydration, the target number instead equals the number of days since the creature last met its daily need for water.

Sleep: At the end of each day, a sleepy creature must succeed on an Easy (2+) Strength test or suffer one level of exhaustion. After two days of wakefulness, the target number instead equals the number of days since the creature last met its daily need for sleep.
