Class skill

Class Skill
Each class has a number of skills that are either exclusive to that class or prefered by it. Some skills are not avaialable to all classes or only available to one class (such as the Perform skill of a Bard).

A character gets a base allotment of 2, 4, 6, or 8 skill points for each new level, depending on the class to which that level was added. If the character gaining his or her 1st character level overall (that is, gaining his or her first level in any class), add his or her Intelligence modifier to the base skill point allotment for the class and multiply the total by four; then add an extra 4 points of the character is human.

If you buy a class skill (such as Listen for a rogue or Spellcraft for a cleric), your character gets 1 rank (equal to a +1 bonus on checks with that skill) for each skill point. If you buy other classes’ skills (cross-class skills), you get 1/2 rank per skill point. Your maximum rank in a class skill is your character level + 3. Your maximum rank in a cross-class skill is one-half of this number (do not round up or down).
