Alternate items

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

Alternate items, also known as item sets, are a mechanic used to implement multiple otherwise similar, but seperate items. Items within a given set are mutually exclusive; only one will generate in any given game. Backgrounds ignore this mechanic and will come with their designated items, no matter if they actually spawn in the dungeon proper.
