Hit points are your health. When you run out of hit points, you are "beaten all to hell" and will need to heal before you can adventure again.
Your maximum hit points are equal to 20 + the lower of {Strength and Will}. See also use your highest Attribute to calculate Hit Points and Empowered for ways to alter your max hit points.
The Undying Will skill will calculate your as just 20 + Will; Strength is ignored.
If you have 0 hp but but gain enough experience to boost the lower of your strength or will (and therefore your hitpoints), you get the message "You drag yourself back to your feet with a newfound strength." This can occur after combat (e.g. a draw), or anytime you can get XP while at 0 hp (e.g. crafting with Good Worker).

Losing Hit Points
You can lose hit points by:
- being attacked by opponents
- being hurt by something else via a noncombat or choice encounter
- This can happen all over the place, but it's worth noting that misteps in the black book and related areas will always bring you down to 0 hp
- popping Atlas capsules, snorting hound dust, mucking about with gritty ointment, replacing your kidney, improperly handling an eternal sparkler or SDnano memory stick, chewing sabotaged Halloween treats, messing with powdered glass, or trying to slot a shielded emitter into a wired chamber (fool!).
- The eternal sparkler (only obtainable on Metroplex Day, once a year), can reduce your HP by 1 at no other resource cost, useful if you need to set your HP to an exact amount.
