Spellcasting

Version 0.12: This article may not be up to date for the latest stable release of Crawl.

The Spellcasting skill determines how proficient a character is at casting spells from memory. A higher Spellcasting level makes it easier to cast spells by lowering their spell hunger, increasing their spell power slightly, and granting your character more max MP and spell levels. It has a minor effect on spell success rate, but increasing skill in a spell's individual magic schools is better for raising its success rate.

Note that the max MP increase granted by Spellcasting is not cumulative with that of Invocations or Evocations; only the highest of the three is used.

History

Prior to 0.12, this skill had a hidden cost in experience points which was +30%; all species had their aptitudes adjusted to account for this.
