Add a new subrule to the Rule entitled “Combat”. Call it “Eating and Resting” and give it the following text:

A @ who has not Fought in the last 48 hours may Rest.  Resting increases their HP by 5 times their Experience Level, or by 5 if their Experience Level is not defined.  If Resting would increase their HP above their Max HP, it instead sets their HP to their Max HP. 

Whenever an @ Rests, if their Status contains Starving then they die, if their status contains Weak then they become Starving, if their status contains Hungry then they become Weak, and if none of these apply they become Hungry.

An @ with one or more Food Ration items in their Inventory may Eat.  When an @ Eats, they remove a Food Ration from their Inventory.  Also, if they are Hungry or Weak they cease to be, and if they are Starving they become Hungry instead.

In the Rule entitled “Status”, change all instances of the text “Hungry!” to “Weak”.
