Starvation and Thirst

Source Core Rulebook pg. 500
Typically characters eat and drink enough to survive comfortably. When they can’t, they’re fatigued until they do. After 1 day + a creature’s Constitution modifier without water, it takes 1d4 damage each hour that can’t be healed until it quenches its thirst. After the same amount of time without food, it takes 1 damage each day that can’t be healed until it sates its hunger.
