Version 0.21: This article may not be up to date for the latest stable release of Crawl.

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).

Causes

The following can all drain your attributes:

As you gain experience, you regain stats lost through any of these means (except malmutate).

Stats can be more permanently lowered by the following means:

  • Mutations 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).
  • Jiyva's stat shuffling. (will never reduce a stat to zero)

The last two never lower a base stat to zero. Sustain attributes provides no help with any of these, and the stat does not restore naturally.

Effects

The following effects occur when any stat reaches 0:

  • you immediately suffer 2-4 turns of paralysis which ignores a Formicid's stasis
  • you are slowed until the stat completely recovers. (doesn't stack)

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

Collapse (Strength)

Brainless (Intelligence)

  • You can't memorise or cast spells
  • You fail to read scrolls 80% of the time

Clumsy (Dexterity)

Precautions

Any character with a particularly low attribute should be aware of the dangers involved. Any attribute below 5 could conceivably be reduced to 0 by a single unfortunate effect, and below 10 are vulnerable to stat zero from repeated effects.

  • Cursed artefact 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 traps, and mummy death curses can temporarily reduce an attribute by up to 4 in one go. 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.
