If this is indeed an error, then the +1 does not jive with the beginner box remaster, whereas the +2 WOULD jive with it. In the remastered beginner box, during character creation, you essentially get 6 points to boost your attributes... the Heroe's Handbook has every class boosting their key attribute by 3 and then getting a +1 to three other abilities of their choice. This seems much more in keeping with the Player Core pg 91 giving you a +2 to your key attribute and then all classes getting an additional 4 free boosts (again, total of 6). So, if we say Player Core pg 91 is a mistake, how then are we to account for all 4 classes in the beginner box remaster getting a total of 6 points of increase?
