Spellcasting

Version 0.30: 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 higher bonus of the two is used. For this purpose, each level of Spellcasting is twice as effective as Invocations.

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 (equal effect to training Spellcasting and all 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.
