Xom

''Xom is a wild and unpredictable God of chaos, who seeks not worshippers but playthings with which to toy. Many choose to follow Xom in the hope of receiving fabulous rewards and mighty powers, but Xom is nothing if not capricious. Also, there is nothing a follower can do to influence Xom's mood.''

Xom the Unpredictable is a God in Dungeon Crawl.

Chaos Knights start with Xom as their Deity. Xom is essentially a random factor in the game; occasionally, he grants bonuses such as Beserk, Magic Mapping or Speed. At other times, he could Slow or debuff the player greatly, or polymorph them or their enemies.

Praying to Xom will give a selection of random dialogue.
