Blind

There are a few ways in Crawl to blind monsters. This effect causes the monster to treat the player (and other creatures) as if they were invisible, whether or not they actually are. See invisible is rendered useless for the duration of the effect, but sense invisible is not. Currently, only monsters can be blinded: the effect does not exist for players.

In general, the effect of blindness is pretty minor. As many invisi-stabbers find out to their chagrin, aware monsters are reasonably capable of finding invisible players. Blinding does, at least, prevent monsters from using most ranged abilities effectively.

The sources of blindness are as follows:

• Hitting a monster with Dazzling Spray will temporarily blind them
• A possible effect of Zin's Recite ability is to inflict permanent blindness on a monster

One way exists that has since been removed:

• Throwing a pie at a monster would also temporarily blind it, in addition to doing nominal damage.
