House rule for sleep deprivation

@JeremyECrawford What are the rules of sleep deprivation? Con test? And DC is? What are the penalties involved? Damn paranoid rogues! >_<

There's no rule for sleep deprivation. A house rule: 1 level of exhaustion per day w/ less than 5 hrs of sleep. #DnD https://t.co/SDqgrlmXV0
