Intelligence

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

Intelligence (or INT) is one of a character's three main attributes, along with strength and dexterity. Characters who plan on using any of the various schools of magic will benefit greatly from having a high intelligence score.

Intelligence affects the following:

• Reduces chance of spell failure.
• Increases spell power.

If your intelligence is ever reduced to 0 or lower, you will suffer stat zero effects.

Useful Info

• Spell failure: Intelligence reduces failure. For the purposes of failure rate, 6 intelligence is equal to having 1 skill in every non-Spellcasting magic skill.
• Spell power: Before modifiers, intelligence is a INT / 10 multiplier, so 20 intelligence is up to twice as much power as 10 intelligence. However, there is a logarithmic stepdown if power > 50, so doubling INT usually results in less than twice the power.

History

• Prior to 0.26, Intelligence reduced spell hunger per casting by INT × Spellcasting.
