Dungeon Survival

As described previously in the Equipment section, normal characters must consume one day's worth of rations (or equivalent food) and at least one quart of water per day. Failure to consume enough food does not significantly affect a character for the first two days, after which they suffer 1 point of damage per day. Furthermore, at that point the character loses the ability to heal wounds normally, though magic will still work. Eating enough food for a day (over the course of about a day, not all at once) restores the ability to heal, and the character will resume recovering lost hit points at the normal rate. Inadequate water affects characters more swiftly; after a single day without adequate water, the character loses 1d4 hit points, and will lose an additional 1d4 hit points per day thereafter. Healing ability is lost when the first die of damage is rolled.
