You are able to temporarily pass imbue someone else with your knowledge of a particular subject.
Benefit: By spending one minute tutoring another creature with an Intelligence score of at least 3, you can grant that creature the ability to make Knowledge skill checks with a single Knowledge skill which you have improved with the Skill Focus feat. They may make these skill checks with your skill ranks and Intelligence modifier or their own, combining the higher value of each, and with their own miscellaneous modifiers (such as from magic) except for those modifiers granted by your Skill Focus feat, which they benefit from. They are able to retain this benefit for a number of days equal to your loremaster level, after which point their knowledge of the topic reverts to its original state.
