The minimum for each primary statistic is 1 and the maximum is 10. These boundaries can never be broken, even with bonuses or maluses. Each statistic directly modifies certain derived statistics. In addition, every skill is tied to a primary statistic. Some perks require certain minimum attribute values as well.
You get 40 points to distribute among the 7 statistics when creating a character (not taking traits into account).
