modifier (INT) resulting from points invested at character generation and on level up determine how many skill points a class is granted at those times:


 * Character generation


 * Level up

Characters are always granted at least four skill points at character generation, and at least one on level up:

All points do not have to be invested at character generation or level up, so they can be saved for a future level up. After becoming a Jedi, your main character's skill points on level up are determined by Jedi class, but the class skills of the earlier class are retained and those of the Jedi class are gained. Class skills cost one point to raise one rank, while cross-class skills cost two points to raise one rank:

Hence a Scoundrel who becomes a Jedi Consular has all skills as class skills. Points can be invested in class skills to maximum rank equal to level + 3, while they can only be invested in cross-class skills to maximum rank equal to [ (level + 3) / 2].

Total skill points main player characters can invest by level 20 depend on Intelligence, starting class, Jedi class and the level at which they become a Jedi:


 * Level 20 Jedi Guardian or Jedi Consular


 * Level 20 Jedi Sentinel
