Blind

Version 0.34: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.

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.

Immunity

Some monsters have the unblindable flag, which prevents blinding from all sources except Enfeeble and god powers. These include monsters with no eyes, such as jellies and glowing orange brains, and creatures with strong non-sight senses like bats and wargs.

Nonliving and plant creatures are immune to blindness, except from Enfeeble and god powers.

Undead creatures are immune to blindness except from Enfeeble, god powers, and wand of light.
