Sleep Deprivation

A character who needs to sleep must get at least 6 hours of sleep every night. If she doesn’t, she must attempt a Fortitude save (DC = 15 + 1 per previous check) after each night she doesn’t sleep enough. The first failed check causes her to become fatigued and take a –1 penalty to saving throws against effects that cause the asleep condition (see page 273). A second failed check causes her to become exhausted, and the penalty to saving throws against effects that cause the asleep condition increases to –2.
