Telepathic Link (Su): A homunculus can’t initially speak,
but shares a telepathic link with its creator. It knows what
its master knows and can convey to him everything it sees
and hears, out to a range of 1,500 feet.
so it says the homunculus knows everything that the master knows its that true for any thing he is able to do or just knowlegdes. Lets say the master knows how to use a pistol does the homunculus now know how to all so use a gun. Ive been thinking about this all day need some input.
