If the 4 ability score points my companion had were spent in Int, how much smarter does this make my pet? An animal with int of 6 would be as intelligent as any other int 6 creature? Assuming my companion somehow had his score raided to 10 or above, it would gain extra skill points I know, but would it, as an int 10+ entity, be able to comprehend perhaps not speak common, given sufficient time to learn?
