Shadows

Version 0.28: This article may not be up to date for the latest stable release of Crawl.

It reduces the distance the wearer can be seen at and can see.

Shadows is an ego found on scarves. A scarf of shadows reduces your LOS by 1, in turn reducing the distance you can attack or be attacked at.

Strategy

Useful when trying to sneakily steal a rune of Zot. Or to be sneaky in general; less sight means less chances for a monster to wake before you stab them.
- Kobolds have their LOS reduced to 3, which is even tinier.
Scarves of shadow are also useful if you struggle with ranged enemies, such as centaurs. Though a scarf of repulsion is typically better suited for this task, repulsion has no effect on attacks like an orc priest's Smiting.
Characters reliant on ranged attacks might still find the scarf useful, though you'll have less range to blast enemies before they get to you.

Scarves of shadows were added in 0.26. In this version only, scarves of shadows would reduce your spellpower.
