Unique monster

Version 0.27: This article may not be up to date for the latest stable release of Crawl.

Unique monsters are monsters that are generated at most once per game. They are usually much more powerful than normal monsters, but provide much greater experience. As such, they can be considered the "boss monsters" of Crawl (although not every unique is guaranteed to appear in every run, and by no means are you required to slay every unique you encounter).
