You don't need to master them, it's like this:You put one point into intelligence, then you can put one point into strategy.If you upgraded intelligence (10/20) and only upgraded strategy a bit (1/20) and you have nine points to spend, you're able to put them all into strategy to make it 10/20, and you can't upgrade strategy again until you put more points into intelligence.
