Intelligence (Int)
Intelligence determines how well your character learns and reasons. This ability is important for wizards because it affects their spellcasting ability in many ways. Creatures of animal-level instinct have Intelligence scores of 1 or 2. Any creature capable of understanding speech has a score of at least 3. A character with an Intelligence score of 0 is comatose. Some creatures do not possess an Intelligence score. Their modifier is +0 for any Intelligence-based skills or checks.

You apply your character's Intelligence modifier to:

  • The number of bonus languages your character knows at the start of the game. These are in addition to any starting racial languages and Common or Old Porphyran. If you have a penalty, you can still read and speak your racial languages unless your Intelligence is lower than 3.
  • The number of skill points gained each level, though your character always gets at least 1 skill point per level.
  • Appraise, Craft, Knowledge (many specialties), Linguistics, and Spellcraft checks.

Prepared arcane spellcasters may gain bonus spells based on their Intelligence score depending on the class description.
