I've been creating a wizard for upcoming game, and I decided to take improved familiar with faerie dragon as my chosen familiar. I looked at the following rule regarding familiars:
Skills: For each skill in which either the master or the familiar has ranks, use either the normal skill ranks for an animal of that type or the master’s skill ranks, whichever is better. In either case, the familiar uses its own ability modifiers. Regardless of a familiar’s total skill modifiers, some skills may remain beyond the familiar’s ability to use. Familiars treat Acrobatics, Climb, Fly, Perception, Stealth, and Swim as class skills.
My main question here is how can I possibly know from faerie dragon entry which of the skills have the class skill bonus (+3)? Thus, how do I know if i should be using wizard's skill ranks instead of faerie dragons, and how to determine if I do add familiars stat + class skill bonuses or just the stat bonus?
