Stamina Points and Hit Points
Whenever you take damage, it first reduces your Stamina Points (SP). Any damage you take beyond your Stamina Points reduces your Hit Points (HP). When your Hit Point total reaches 0, you fall unconscious and are dying, and you lose 1 Resolve Point (RP) each round unless you are stabilized. When your Resolve Points reach 0 but you would lose additional Resolve Points from dying or for any other reason, you’re dead. For example, if you have 6 Stamina Points and take 9 damage, your Stamina Points are reduced to 0, you lose 3 Hit Points, and all subsequent damage reduces your HP until you regain Stamina Points. See Injury and Death on page 250 for more information.
