When one of a character's primary [[attributes]] ([[Strength]], [[Intelligence]], or [[Dexterity]]) is lowered to 0 or below, the character will suffer some important 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 (capped to 200 turns).

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: <code>10 + 1d10 + the number of turns it was below 0</code> (Max: 200 turns).
  
==Causes==

==Effects==
The following can all drain your attributes:
+
The following effects occur when any stat reaches 0:
*By 1 at a time, and affected (and thus blocked) by [[sustain abilities]]:
+
 
**The [[bad mutations#Deterioration|Deterioration]] mutation. Rank 1 can generally be kept in check by your natural regeneration; ranks 2 and 3 of this mutation are eventually lethal, however.
+
*You immediately suffer 2-4 turns of [[paralysis]], which ignores a [[Formicid]]'s [[stasis]].
**[[Sickness]]
+
*You are [[slow]]ed until the stat completely recovers.
**The special attacks of certain monsters ([[brain worm]]s, [[quasit]]s, [[shadow]]s, etc.).  Although all three stats can be drained, INT is by far the one most commonly affected.  This is because it is drained by a smite-targeted spell, where the others are drained only through melee attacks.
+
 
**Decomposition (not to be confused with [[rotting]]) from attempted [[mutation]] of an undead character.
+
The following effects are dependent on the specific stat which was drained to 0:
*By more than 1 at a time, but damage can be halved by [[sustain abilities]]:
+
 
**Evoking certain items, such as a [[crystal ball of energy]] or the [[staff of Wucad Mu]].
+
===Collapse (Strength)===
**Spell [[miscast effect]]s, as caused by actual miscasts, [[Hell]] effects, and mummy [[death curse]]s.
+
*You do not regenerate [[HP]] when monsters are in sight.
**[[Zot trap]]s.
 
**Certain spells, such as [[Summon Horrible Things]] or [[Alistair's Intoxication]], have a chance of draining INT when cast.
 
*By varying amounts, and not affected at all by sustain abilities:
 
**Equipment with negative stat modifiers (but you can remove the equipment to restore the stat).
 
  
Stats can be more permanently lowered by the following means:
+
===Brainless (Intelligence)===
*[[Mutations]] which affect attributes (directly, or through stiff/loose muscles, some scale mutations, etc.).
+
*You can't memorise or cast [[spell]]s.
*The [[Deck of wonders#Focus Card|Focus]] card.
+
*You fail to read [[scroll]]s.
*[[Jiyva]]'s stat shuffling.
 
*The [[Shuffle#Shuffle Card|Shuffle]] card.
 
  
The last two will never lower a base stat to zero.
+
===Clumsy (Dexterity)===
 +
*Your [[EV]] score is set to <code>2 + size_bonus + [[Repulsion field]] bonus</code>.
 +
*Your [[SH]] score is set to 0.
 +
*Your [[stealth]] score is set to 0.
 +
*You can't [[stab]] monsters.

==Causes==
There are three different [[status effect]]s depending on which attribute has reached 0:
+
The following sources of '''stat drain''' can all temporarily lower your attributes ([[Str]], [[Int]], [[Dex]]):
  
===Collapse===
+
'''By 1 at a time:'''
It happens when your strength is 0 or less:
+
*The [[bad mutations#Deterioration|Deterioration]] mutation.
*The speed of all your actions is halved (stacks with other stats' speed penalties)
+
*The melee attacks of certain monsters:
*Your [[regeneration rate]] is divided by 4
+
**{{monsterlink|Quasit}} (dexterity only)
*Your carrying capacity (calculated with str=0) is halved
+
**{{monsterlink|Ghost moth}}
 +
**{{monsterlink|Eidolon}}
 +
*Decomposition from attempted [[mutation]] of an undead character.
  
===Brainless===
+
'''By more than 1 at a time:'''
It happens when your intelligence is 0 or less:
+
*[[Corrupting Pulse]] can give transient (temporary) mutations, which can include [[Bad_mutations#Reduced_Attributes|Reduced Attributes]] (-2 stat).
*The speed of all your actions is halved (stacks with other stats' speed penalties)
+
**{{monsterlink|Wretched star}}
*You can't read [[book]]s
+
*[[Brain Feed]]: Drains 1-3 intelligence in one go.
*You can't cast [[spell]]s
+
**{{monsterlink|Glowing orange brain}}
*You will fail to read [[scroll]]s 4 of every 5 times
+
**{{monsterlink|Neqoxec}}
 +
**{{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.
 +
*Casting spells while wielding the [[staff of Wucad Mu]], which can drain 1-5 intelligence.
 +
*Stepping on or being in view of a monster stepping on [[Zot trap]]s, which could drain 1-4 stat points.
  
===Clumsy===
+
As you gain experience, you regain stats lost through temporary drain or mutation.
It happens when your dexterity is 0 or less:
 
*The speed of all your actions is halved (stacks with other stats' speed penalties)
 
*Your [[evasion]] is set to 2 + size_bonus + [[Phase Shift]] bonus + [[Repulsion field]] bonus
 
*Your [[stealth]] is set to 0
 
*You can't [[stab]] monsters
 
  
When a stat reaches 0, you will suffer 2 to 5 turns of [[paralysis]]. Losing stat points from a stat that is already below 0 also inflicts some HP damage: 4 + 1d(max hp/10)
+
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]].
 +
*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 8 could conceivably be reduced to 0 by a single unfortunate effect, some of which are common, some less so.
+
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.
*Cursed equipment can reduce an attribute by up to 6 for as long as it's equipped, so be cautious about wearing unidentified items if you're at risk.
+
 
*Miscast effects, Hell effects, [[Zot trap]]s, and [[mummy]] [[death curse]]s can temporarily reduce an attribute by up to 7. You may wish to bring all of your attributes up to a minimum of 8 to guarantee that you can survive a single worst-case scenario shot from either one. Alternatively, you could eat a [[royal jelly]] to restore all attributes instantly. Just remember that "Engorged" characters cannot eat any further.
+
Specifically, [[Hell]] effects can reduce an attribute by up to 5 in a single go, while [[Zot trap]]s, and [[mummy]] [[death curse]]s 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.

Version 0.29: 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.
