Hit points

Version 0.31: This article may not be up to date for the latest stable release of Crawl.

A character's hit points (or HP) reflect their current healthiness and durability, and are displayed in an X/Y format; the X shows your current hit points, while the Y shows your maximum. Monsters and a wide variety of other effects will all reduce your current HP, but this recovers over time unless you are sick.

Damage

If at any time your character's current HP reaches 0 or lower, you die and your game is over. You can avoid this by resting between battles, quaffing potions of heal wounds or curing, or using any of the more exotic healing methods available.

Be very careful if you ever see the message, "Ouch! That really hurt!" pop up - it occurs after you've lost over 50% of your max HP in a single attack.

Regeneration

Main Article: regeneration rate

Characters which are not sick or under Inhibited Regeneration will naturally recover health over time.

HP modifiers

From Dungeon Crawl Stone Soup in-game documentation:

At	Ba	Co	DE	Dg	Ds	Dj	Dr	Fe	Fo	Gr	Gh	Gn	Hu	Ko	Mf	Mi	MD	Mu	Na	Op	On	Sp	Te	Tr	Vp	VS
1	0	0	-2	1	0	-1	1	-3	0	-2	1	0	0	-2	0	1	1	0	2	-1	3	-3	-2	3	0	-3

Each point is equal to 10% maximum HP.

Modifying Max HP

Forms

The following forms will change your maximum HP:

Spell	Modifier
Serpent Form	1.2
Statue Form	1.3
Dragon Form	1.5
Tree Form	1.5

If are in a talisman form and do not have the minimum Shapeshifting skill, you get an HP penalty. The penalty is 1 - (Skill_min - Skill_current)/10 (min. x0.1).

Statuses

• Berserk will multiply your current and maximum HP by 1.5. Bearserk multiplies it by 2.
• Drain will reduce max HP proportionally to its strength.
• Elyvilon's Divine Vigor increases your max HP temporarily by your Invocations.

Mutations

• Gaining the Robust mutation increases your max HP by 10% per rank, while Frail decreases it.
• Gaining the Rugged Brown Scales mutation increases your max HP by 3/5/7% (determined by rank).

Items

• The Rings of the Octopus King give you +2 HP.

Permanent

Your permanent max HP only changes under rare circumstance:

• Leveling up:
  • Gaining an experience level.
  • Improving your Fighting skill will increase max HP.
• Casting Borgnjor's Revivification permanently reduces your max HP by a small amount, determined by spell power.
• Running out of time on the Zot clock permanently reduces your max HP by 16.6%.

The formula is:

 Max HP = (Racial Mod.) * (Mutations Mod.) * (Forms Mod.)
        * (8 + 11*XL/2 + Fighting*XL/14 + (1+Fighting*3)/2)

History

• In 0.29, the Zot clock would only apply drain instead of permanent HP reduction. Prior to this, the Zot clock instantly killed you upon running out.
• Prior to 0.26, rot existed, lowering maximum HP temporarily, like Drain does now. However, it could be cured with a potion of heal wounds or potion of curing.
• Prior to 0.14, backgrounds had a small effect in the calculation of the player's hit points.
