Master / Familiar Abilities for Familiar Master Dedication

[Rakshara of the Flame]

Scenario:
1st Level - get a Familiar (2 master/familiar abilities)
2nd Level - take Familiar Master Dedication (4 master/familiar abilities)
6th Level - take Improved Familiar (The number of abilities required to make your
familiar a specific familiar (page 147) is two lower than normal.)

You now have four abilities and can take the Fairie Dragon Familiar, which requires six abilities.

10th level - take Incredible Familiar (You can select six familiar or master abilities each day, instead of four.)

Does Incredible Familiar + Improved Familiar mean I can give two *optional* master/familiar abilities to my Fairie Dragon each day?

[Kyrone]

Yes, because you already paid the 4 abilities price to buy the fairy dragon and now have 2 to spend how you want.

[Moximus]

I don't think so. In the rules for familiar abilities, it states "If your familiar is an animal that naturally has one of these abilities (for instance, an owl has a fly Speed), you must select that ability." The Faerie dragon has "amphibious, darkvision, flier, manual dexterity, speech, touch telepathy", so I think you have to choose those with your 6 ability choices. Have gotten the Farie Dragon when you had 4 ability choices says nothing about being able to bypass this general rule.

Hmm.

You can’t have a familiar with more natural abilities than you have familiar abilities to spend on those.

Under your interpretation Moximus, I’m not sure that Improved Familiar actually does anything. If you have to assign the abilities as listed, but you also can’t get earlier access, and once you have more than 6 abilities it becomes irrelevant anyway, what does it actually do?

Specific Familiars

...
A specific familiar has several traits and abilities, as listed in their stat block. The Granted Abilities entry lists normal familiar and master abilities that familiar has. The familiar also gains unique abilities listed below the Granted Abilities entry. Much like a familiar that naturally has a familiar ability (such as an owl with a fly Speed), you can never swap out any of these granted or unique abilities. If your familiar gains more abilities than are necessary for that specific familiar, you can use the remaining abilities to select familiar and master abilities as normal.

Since Improved Familiar reduces the number of necessary abilities by two, it seems to me that the two extras granted by Incredible Familiar would be yours to choose.
