Version 0.28: This article may not be up to date for the latest stable release of Crawl.
If you were looking for the "Brainless" status condition caused by having 0 Intelligence, see Stat zero.

All monsters have a level of intelligence that determines certain behaviours, such as tracking the player, avoiding danger, and cooperating with allies. In general, a monster's intelligence is a secondary consideration compared to its physical and magical abilities, but it does have a number of effects, mostly in fairly specific situations.

Levels of Intelligence

There are three levels of monster intelligence:

  1. Brainless intelligence: Plants, zombies, jellies, golems, elementals
  2. Animal intelligence: Animals, insects, some non-zombie undead
  3. Human intelligence: Humanoids, some other powerful/magical monsters

Effects of intelligence

The following is a non-exhaustive list of effects of monster intelligence.

  • Brainless monsters will blunder into shallow water, traps and dangerous clouds (except miasma). Intelligent monsters will avoid clouds unless they are resistant. A strong enough intelligent monster may choose to charge through a weak effect.
  • Non-brainless monsters will often try to make space for their allies to attack you.
  • Intelligent monsters search and travel more effectively, and will continue to hunt for you longer after hearing noise or losing sight of you.
  • Intelligent ranged monsters will attempt to regain line of sight rather than charging directly at you.
  • Non-brainless monsters will retreat if they can't reach you or shoot at you.
  • Intelligent monsters may be able to guess your location even when you are invisible.
  • Brainless monsters cannot be pacified, bribed, or have their souls stolen by Yredelemnul.
  • Brainless monsters cannot be affected by Anguish, or have their minds burst.

History

  • Prior to 0.28, the monster intelligence of your allies determined avoidance of traps (no effect on hostile).
  • Prior to 0.26, butchering intelligent creatures would anger Zin.
  • Prior to 0.17, there were 6 categories of intelligence: plant, insect, reptile, animal, human and high.
  • Prior to 0.13 reptile intelligence and insect intelligence were one value, and Elyvilon could thus pacify insects. Also, friendly dumb monsters wouldn't turn hostile when damaged by ranged attacks.
