Kitsune gain several "choose one of these spells during your daily preparation" feats. When combined with Ancestral Mage do they gain all the choices as signature spells or only the choice they made for the day?
For example would a Kitsune with Kitsune spell Expertise have Death Ward, Confusion, and Illusory Scene as signature spells?
Or if the Kitsune chose Death Ward for the day would that be the only spell they gain as a signature spell for the day, and when they chose confusion the next day that would be the signature spell?
When you pick one of the spells, you lose access to the other two, so only the spell you picked for that day is added to your repertoire. They are not added as signature spells, but to your repertoire at the same level you would normally be able to cast them as innate spells.
Good point, I mixed my words up on signature and repertoire thank you. I thought it would work like you stated but wasn't certain.
