When one of a character's primary [[attributes]] ([[strength]], [[intelligence]], or [[dexterity]]) is lowered to 0 or below, the character will suffer crippling penalties until that attribute is restored and stays above 0 for a period of time equal to: 10 + 1d10 + the number of turns it was below 0 (Max: 200 turns).

The following effects occur when any stat reaches 0:
*By 1 at a time, and thus blocked by [[sustain abilities]]:
 
**The [[bad mutations#Deterioration|Deterioration]] mutation. Rank 1 is generally kept in check by your natural regeneration, but ranks 2 and 3 are eventually lethal.
 
**[[Sickness]].
 
**The special attacks of certain monsters [[quasit]]s (dexterity only).
 
**Decomposition (not to be confused with [[rotting]]) from attempted [[mutation]] of an undead character.
 
*By more than 1 at a time, but damage can be halved by [[sustain abilities]]:
 
**[[Brain Feed]].
 
**Spell [[miscast effect]]s, as caused by actual miscasts, [[Hell]] effects, and mummy [[death curse]]s.
 
**Evoking certain items, such as a [[crystal ball of energy]] or the [[staff of Wucad Mu]].
 
**Stepping on or being in view of a monster stepping on [[Zot trap]]s.
 
**Certain spells, such as [[Summon Horrible Things]] or [[Alistair's Intoxication]], have a chance of draining INT when cast.
 
Unless you have [[Slow Healing]] 3 (which [[Deep Dwarves]] have innately), you will slowly regain stats lost through any of these means.
 
  
Stats can be more permanently lowered by the following means:
+
*You immediately suffer 2-4 turns of [[paralysis]], which ignores a [[Formicid]]'s [[stasis]].
*[[Mutations]] which affect attributes (this lasts until the mutation is removed [[somehow|potion of cure mutation]]).
+
*You are [[slow]]ed until the stat completely recovers.
*Equipment with negative stat modifiers (but you can remove the equipment to restore the stat).
 
*The [[Deck of wonders#Focus Card|Focus]] card.
 
*[[Jiyva]]'s stat shuffling.
 
*The [[Shuffle#Shuffle Card|Shuffle]] card.
 
  
The last two will never lower a base stat to zero. Sustain abilities provides no help with any of these, and the stat will not restore naturally.

==Effects==
 
When any stat reaches 0, you will immediately suffer 2-4 turns of [[paralysis]] which ignores [[stasis]]. Stat zero will also inflict various penalties for each stat reduced to zero:
 
  
 
===Collapse (Strength)===

*The speed of all your actions is halved (stacks with other stats' speed penalties)

*You can't cast [[spell]]s
 
*You will fail to read [[scroll]]s 4 of every 5 times
 
  
 
===Clumsy (Dexterity)===
 
===Clumsy (Dexterity)===

*Your [[stealth]] is set to 0
+
*Your [[stealth]] score is set to 0.
*You can't [[stab]] monsters

*You can't [[stab]] monsters.
  
Losing stat points from a stat that is already below 0 also inflicts some HP damage: 4 + 1d(max hp/10). If a character dies from this damage, the stat death is recorded (weakness, clumsiness, stupidity).

==Causes==
 +
The following sources of '''stat drain''' can all temporarily lower your attributes ([[Str]], [[Int]], [[Dex]]):

'''By 1 at a time:'''

**{{monsterlink|Ghost moth}}
 +
**{{monsterlink|Eidolon}}
 +
*Decomposition from attempted [[mutation]] of an undead character.
 +
 
 +
'''By more than 1 at a time:'''
 +
*[[Corrupting Pulse]] can give transient (temporary) mutations, which can include [[Bad_mutations#Reduced_Attributes|Reduced Attributes]] (-2 stat).
 +
**{{monsterlink|Wretched star}}
 +
*[[Brain Feed]]: Drains 1-3 intelligence in one go.
 +
**{{monsterlink|Orange crystal statue}}
 +
*[[Hell's mystical force]] can drain up to 5 stat points when you descend down a stair, and can also give transient mutations.
 +
*Mummy [[death curse]]s drain from 1-4 of a random stat.
 +
*Quaffing a [[potion of degeneration]] drains 1-3 of each stat.
 +
*[[Throw Klown Pie]] can drain 1-3 of each stat.
 +
**{{monsterlink|Killer Klown}}
 +
*Stepping on or being in view of a monster stepping on [[Zot trap]]s, which could drain 1-5 stat points.

As you gain experience, you regain stats lost through temporary drain or mutation.

Stats can be more permanently lowered by the following means:

*[[Mutations]] (such as from [[Malmutate]]) which affect attributes. This lasts until the mutation is removed [[potion of mutation|somehow]].

Version 0.31: This article may not be up to date for the latest stable release of Crawl.
"Brainless" redirects here. If you were looking for the monster intelligence category, see Category:Brainless intelligence.

When one of a character's primary attributes (strength, intelligence, or dexterity) is lowered to 0 or below, the character suffers crippling penalties until that attribute is restored and stays above 0 for a period of time equal to: 10 + 1d10 + the number of turns it was below 0 (Max: 200 turns).

Effects

The following effects occur when any stat reaches 0:

The following effects are dependent on the specific stat which was drained to 0:

Collapse (Strength)

  • You do not regenerate HP when monsters are in sight.

Brainless (Intelligence)

Clumsy (Dexterity)

Causes

The following sources of stat drain can all temporarily lower your attributes (Str, Int, Dex):

By 1 at a time:

By more than 1 at a time:

As you gain experience, you regain stats lost through temporary drain or mutation.

Stats can be more permanently lowered by the following means:

  • Mutations (such as from Malmutate) which affect attributes. This lasts until the mutation is removed somehow.
  • Equipment with negative stat modifiers. But, you can remove the equipment to restore the stat.

Precautions

Any character with a particularly low attribute should be aware of the dangers involved. Any attribute below 6 could conceivably be reduced to 0 by a single unfortunate effect, and below 11 are vulnerable to stat zero from repeated effects.

Specifically, Hell effects can reduce an attribute by up to 5 in a single go, while Zot traps, and mummy death curses reduce up to 4. You may wish to bring all of your attributes up to a minimum of 9 to guarantee that you can survive two worst-case scenario effects from the latter. All three happen reasonably late in the game, so early level ups should not take stat zero into account (unless you find a great stat-reducing artefact).

Outside of the extended game, stat zero only realistically happens to the extreme end of combinations, such as a Minotaur Berserker or Deep Elf Conjurer. A human, for example, is normally much less vulnerable to its effects.

History

  • Prior to 0.28, zero intelligence only had an 80% chance to fail reading scrolls. Zero strength's -Regen was a flat regen/4 modifier.
  • Prior to 0.19, sustain attributes existed which would halve stat damage. Hence, multi-point stat damage was roughly halved in 0.19.
  • Prior to 0.17, taking further stat damage after a stat reached 0 would inflict HP damage.
  • Prior to 0.15, items had mass, and strength determined your carrying capacity. Collapse seriously reduced this.
  • Stat zero was added in 0.13, replacing stat death.
