Intelligence

Intelligence (Int) determines how well your character learns and reasons, Intelligence is important for Scouts, Nobles, and any character who wants to have a wide assortment of Skills.
You apply your character's Intelligence modifier to:
The number of Languages your character knows at the start of the game. The number of Trained Skills you have. Knowledge, Mechanics, and Use Computer checks (the Skills with Intelligence as the key ability). Beasts have Intelligence scores of 1 or 2. Sentient creatures have scores of at least 3.
When a character's Intelligence score permanently increases or decreases, its number of Trained Skills and known languages also changes. For example, if Paul's Wookiee Scout increases his Intelligence from 13 to 14, his Int modifier goes from +1 to +2. Paul's Wookiee gains one new Trained Skill (chosen from his list of Class Skills) and one new Language.
