Applied Learning

A positive Intelligence modifier grants additional non-skill proficiencies per point, such as a new language or tool. A negative Intelligence modifier removes only one additional non-skill proficiency (though never Common or the language of their heritage), regardless of the value (e.g. a -3 Intelligence modifier still removes only one non-skill proficiency).

At any level where your Intelligence modifier permanently increases (e.g. through gaining a level or taking a feat), you may add another non-skill proficiency.
