Add a sub-rule titled “Health” to the rule “Character Sheets” with the following text:

Each Adventurer has an amount of Health Points (or HP, for short).  Each Adventurer starts with 10 HP.  An Adventurer’s HP may never rise above 10.  If an action would cause an Adventurer’s HP to be set to a value greater than 10, set it to 10 instead.  Whenever an Adventurer’s HP is 0 or less, that Adventurer ceases to be part of any Party and is considered Dead for 48 hours, after which he is no longer considered Dead and his HP is set to 1.  As long as an Adventurer is Dead, he may not join any Party.

To “heal X HP” means to add X to the HP of the target.  To “hit for Y HP” means to subtract Y from the HP of the target.

Non-Adventurer Characters (or NPCs, for short) also have HP.  A NPC’s HP shall be set at the time of creation of the NPC.  Whenever a NPC’s HP is 0 or less, it ceases to exist.
