She gets YYYYGG for 6 in Int and 4 in the skill that uses Int. It confused me for a while too but then I realized the max characteristic for a PC is 6.Just out of curiosity? How can someone get YYYYGG??? I get 5 Ranks, but that would get you 1G not 2. So she would have 4INT and 5 ranks?? That would be YYYYG...and if she gets her 5th point in INT then it would be YYYYY.
Personally I wouldn't have done this to a character I'd play. It makes you a one trick pony. I prefer a more balanced approach.
Honestly, its pretty easy to become a multi-trick pony with a high intellect. Medicine, mechanics, computers, and the knowledge skills all use intellect. Unlike the social skills or combat skills, all 3 of those serve a very distinct and separate purpose. Assuming this character is a technician, with 50 XP she could be rolling the same dice pool on mechanics, less if she has any ranks in it already.
