Spellcasting

Version 0.28: 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 gives your character more spell levels and increases your max MP. It also has a minor effect on your spell power and spell success rate, but increasing skill in a spell's individual magic schools has a greater effect on both attributes.

Note that the max MP increase granted by Spellcasting is not cumulative with that of Invocations; only the highest of the two is used. For this purpose, Spellcasting is twice as effective.

Djinn

The Innate Casting of a Djinni gives Spellcasting a unique purpose: Spellcasting skill does not raise their MP or HP, but instead determines their spell power for all spell schools (with the same effect as the other magic schools). While the -3 aptitude seems terrible at first, keep in mind that it counts as double (i.e. an effective +1 aptitude) for dual-school spells, and that every spell you get can run off a single skill.
