Summary:
The hero creation system states that each skill increase has a point cost of 10, yet, the heroes in S-13.1 to S-13.14 show different point values for passive and active skill ranks.
Correction:
The fields should read 10 Pts for each skill increase (the calculator also uses 10 Pts per skill). The values 5 - 25 Pts should be treated "Optional".
Background:
During play testing, a more detailed approach to skill increases was tested that differed between passive and active skills and attributed between 5TPC for Rank1 and up to 25TPC for Rank4. This was dropped for faster play and less complexity.
Just like the optional stat costs on page 173 (the higher the more expensive) players can work with these point costs to encourage the raising of cheaper low level skills during the early stages of a campaign game.
Keep in mind that this will make management of your party more complex and not as fast (like moving the slider from arcade-style to rpg-style).
