Version 0.25: This article may not be up to date for the latest stable release of Crawl.
For most species the default line of sight (LOS) is a 15x15 square (for Barachim it is a 17x17 square).
There are some ways to change your line of sight:
- The spell Darkness reduces LOS by 25%. The same effect is also provided by the Robe of Night.
- The demonspawn-exclusive nightstalker mutation reduces LOS by 1, 2, or 3 tiles depending on its rank.
The following picture shows tiles within the default field of view with their grid distance.

Strategy
If you can't see them, they can't see you. With very few exceptions, enemies that can't see you can't attack you.
There are several ways to break your line of sight with an enemy:
- Teleporting/blinking out of range
- Closing doors
- Turning a corner
- Reading a scroll of fog
- Going up/down stairs or shafts
- Imprisoning them, or yourself
- If you are faster than them, you can also run away.
History
- In 0.26, Kobolds will start with Nightstalker 3; Demonspawn will no longer have Nightstalker among their possible mutations. Also, scarves of shadows will be added.
- In 0.20, Barachim, and their unique +LOS mutation were added.
- Prior to 0.19, the Shadow card existed and could be used to further reduce the player's LOS.
- Prior to 0.18, the lantern of shadows existed and could be used to further reduce the player's LOS.
- Prior to 0.17, line of sight was circular with a radius of about 8.
- In 0.7, the developers made an undocumented change to the LOS. Ranges are circular now, so every spell and ability that reaches a set distance got about two squares lopped off the diagonals. Stealthy characters can now reach their target in 5 squares (instead of 8) at certain angles.
