Your capacity to learn a particular skill increases.
Benefit: The maximum ranks in one of your class skills increases by +3 (i.e., it’s now CL +6). You can take this feat multiple times. Each time, it applies either to a new skill or it stacks with an existing Skill Aptitude feat. If you take this feat 5 times in a single skill, then you have no Max Ranks in that skill any more, and you can take as many ranks in it as you can afford.
Normal : Your maximum ranks in a class skill is Level +3.
