Every class has access to one bailiwick skill representing specialized knowledge gained by being a member of that class, which is not available to people outside of those classes. The six bailiwick skills are:
Characters are always naturally talented in their own bailiwick skill, meaning they can re-map it to the ability modifier of their choice. Once the modifier for their bailiwick skill is selected, it may not be changed, except through the Character Reselection rules. Note that naturally talented skills, and thus bailiwick skills, never suffer an armor check penalty, even if they are mapped to STR or DEX modifiers.
Characters may not place ranks in bailiwick skills which are not specifically available to them via their character class (or in some cases, from a racial trait). Characters cannot train fellow party members in their bailiwick skills, as the knowledge provided by these skills is gained by spending every hour of every day performing the actions of the classes which offer those skills. It's too specialized to teach to an outsider.
If you gain a second bailiwick skill (usually through a racial trait), it is not automatically a natural talent (even though you typically get to choose which of your ability score modifiers is aligned to the second bailiwick skill). Armor check penalties do apply to the second bailiwick skill if you choose to associate it with your STR or DEX modifier.
- Each Bailiwick skill has a linked knowledge skill. For each rank a character places in their bailiwick skill, the character receives a free rank in that bailiwick skill's linked skill. Note that no character may ever have more ranks in a skill than their character level.
- Skill uses for the linked skills are not interchangeable with the bailiwick skill (i.e. you can't use Spycraft to gather information, you must still use your Knowledge (Local) check to do that). Furthermore, the linked skill is not automatically a natural talent, though you can certainly make it one, if you wish.
- If a character has more than one bailiwick skill (usually via a racial trait), the second bailiwick skill does not gain matching ranks in its associated linked skill.
