Version 0.32: This article may not be up to date for the latest stable release of Crawl.

Blind is a status effect which causes monsters to treat all creatures as if they were invisible, ignoring see invisible. Players instead get an accuracy penalty that scales with distance.

Dazzled has identical effects to blindness, but with a shorter duration.

Blindness

The effects of blindness vary if the victim is a monster or player:

Monsters: Monster behavior is the same as if the player goes invisible and the monster cannot see invisible.

  • Blind attackers receive a -35% penalty to to-hit rolls
  • Blind enemies cannot perform attacks of opportunity.
  • Blind ranged attackers will often target the wrong tile, potentially hitting other targets or missing entirely.
  • Anything with animal intelligence or worse will occasionally move as though confused, rather than pursuing or attacking you. Anything of human intelligence can still track you normally, however.
  • Blind enemies are susceptible to low-tier stabbing attacks.

Players:

  • Players suffer a 15 * (distance + 1)% miss chance penalty to all attacks that check EV, where distance is how many tiles away the target is.
    • The maximum miss chance from this penalty is 90%
  • The screen gains a filter depending on the source.

Sources

Player and monster:

Players only:

Against the player:

Some monsters, e.g., wargs and bats, cannot be blinded by any means. Only monsters of natural, demonic, and holy holiness can be blinded (non-living and plant creatures are immune). On the other hand, only undead players (not counting living vampires) are unblindable and undazzleable.

History

  • Prior to 0.32, blindness against players simply caused confusion. Many new sources of player blindness were added in this version.
  • Prior to 0.31, creatures with non-living and plant holiness could be blinded by wands of light.
  • Wands of light were added in 0.29.
  • The cloak of Starlight gained *Dazzle in 0.26.
  • Prior to 0.16, the sense invisible monster intrinsic would stop blindness.
  • During the brief period in which jesters existed, you could also temporarily blind monsters by hitting them with pies.
