Intelligence is one of the six attributes: Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma. Your Intelligence score is added to many knowledge, analysis, and technical skills (such as Computers, Crafting, and various Lore skills), and is folded into most “smart” class builds.

Some classes in Starfall, like the Mechanic, explicitly key off Intelligence as a “key attribute,” gaining starting proficiencies in Computers, Crafting, and extra trained skills that are partly driven by the Intelligence modifier
