First of all, sorry for my poor english.
I am doing a rom hack for sacred stones where I am changing each character's class through nightmare, I know that every class is set in the first chapter a character appears, but I don't know exactly where are the creature campaign characters "first chapter" seeing as how they join after you "achieve" certain things.
I have read somewhere that the creature campaign characters are given through events, but I don't know exactly how to change events in nightmare, so I would like to ask if someone can please explain me how to do it.
