PIETY: Piety is another extremely important attribute to most of the spellcasting classes. For all classes except liches, piety determines how often you regain hit points and magic points. If your piety is lower, you will tick less often then if it is high, and your character wont regenerate his hit points and magic back as quickly. Piety also helps you to search. Also, the lower your piety is, the most likely an aggressive monster will attack you as opposed to someone else in the room with a higher piety. Generally, the higher your piety is, the more you will heal back when you use the vigor or mend wound spells.
