Intelligence determines how well your character consciously learns, reasons, and remembers. This ability is important because it affects how many Arcane spells a character can cast, and how powerful their spells can be. It’s also important for any character who wants to have a wide assortment of knowledge. Intelligence also relates to how your character conceptualizes their own sense of alignment.

You apply your character’s Intelligence modifier to:

• The number of languages your character speaks at the start of the game, beyond their own species language.

• Appraising, Crafting, Forgery, Knowledge, Language, Lip Reading, Navigation, Ventriloquy, and Intelligence Profession checks. These are the skills that have Intelligence as their key ability.
• Number of Disciplines and Skills a character begins with at 1st Level.

Arcane spell-casters gain bonus spells based on their Intelligence score. The minimum Intelligence score needed to cast an Arcane Magisteria spell is 10 + the spell’s level.

An animal has an Intelligence score of 1 or 2. A creature of humanlike intelligence has a score of at least 3. Average is around 10.
