HP

For those of you who have never played a role playing game before, HP stands for Hit Points. It's a measure of how much physical damage your character can take. Hit Points are directly based on how much Muscle you have, although Muscle classes inherently have 50% more HP than everyone else.

When your Hit Points are reduced to zero, you cannot adventure until you regain some, either by using healing items or resting at your campsite. You also spend a few turns Beaten Up, which effectively reduces your primary statistics by half. You cannot go below zero HP, and you cannot die.

There are many weapons, pants, hats, and accessories to equip to increase your total HP. For a comprehensive list of everything in the game that affects your maximum HP, see HP Increasers.

There are some effects which can reduce your Muscle and thereby your maximum HP, but your HP can never be less than what you would get with just your unbuffed Muscle.

Resting in one's campground, using various items, and taking along specific familiars will also restore some of your HP. For a comprehensive list of everything in the game that restores HP, see HP Restorers.

Try to adventure with 0 HP yields the following message:

You can still, in fact, vacation though.

Notes

Your HP ceiling is affected by several effects and skills:

Max HP =
  S +
  CEILING(
    G × CEILING(
      A × CEILING(
        R × MAXIMUM(
              FLOOR((M + 3) × C) + P,
              FLOOR(m × C)
        )
      )
    )
  )

Where:

• M is your buffed Muscle
• m is your base Muscle
• C is 1.5 if you are a Muscle class (1 for other classes)
• S is your HP bonus from Slimy Sinews
• P is the total of other direct HP bonuses you have (e.g., from a bejeweled accordion strap)
• R is 1.25 if you have Spirit of Ravioli (1 if you don't)
• A is 1.1 if you have Abs of Tin (1 if you don't)
• G is 1.05 if you have Gnomish Hardigness (1 if you don't)

Assuming your Muscle is not suffering from a net negative effect, the formula can be approximated using:

Max HP ≈ GAR[(M + 3)C + P] + S = 3GARC + GAR(CM + P) + S

What this means in practice is that, when trying to maximize your HP and wanting to choose the best outfit for that goal, you should choose the items that give the largest value of

C × EquipmentMuscleBuff + EquipmentHPBuff
