Chronic Fatigue (Disability)

Roll a d20 at the end of a long rest. On a roll of 2 or lower, take one level of exhaustion. This number can be adjusted for the severity of chronic fatigue to increase or decrease the odds of being penalized. (Optional: Critical failure adds two levels of exhaustion. Alternative optional rule: you take twice as long to remove exhaustion as other players.)

When you take this disability, you may take an additional feat or give a +1 to two ability scores or a +2 to one ability score.
