At each level, a character gets skill points that are used to buy
skills. The character's class and Intelligence modifier determine the number of points received.
If the character buys a class
skill, he or she gets 1 rank in the
skill for each
skill point spent. If the character buys a cross-class
skill, he or she gets ½ rank per
skill point. The maximum rank in a class
skill is equal to character level + 3. The maximum rank in a cross-class
skill is one-half of this number.
