I'm afraid I'm going to need some help with the cost for skill ranks. So getting to D rank should cost a total of 2 points. C a total of 5 points. B a total of 9 points. A a total of 14 points and finally S with a total of 20 points. Yes? And does having only 1 weapon give you an extra point, As in 14->15 points? Or an extra rank, As in 14 points, and 1 rank up?
