Q 127b

Is Knock-down a deity specific feat; can it only be taken by a deity/with the DM's permission?

No, it is not. The only reason that feat is in that section of the SRD is that it was printed in Deities and Demigods. It was printed in Deities and Demigods because it had previously been printed in some other book - where it was intended for regular characters - and someone wanted to use it for an official deity build but the book was required to be self-contained except for core.

Every feat in that section of the SRD was originally printed in a book other than Deities and Demigods, and in that original printing it was intended for normal characters. Also, while it says that deities can take these feats, it does not say that non-deities cannot. The prerequisites listed in each feat are the only prerequisites actually required, and divine rank is not among them. Just make sure what you're looking at is in the feats section, not the Salient Divine Abilities section.

Q128 A
If a natural 20 is rolled on a critical confirm, but 20 + to-hit < AC, then does the attack crit?

Yes.

Q128 B
If a natural 1 is rolled on a critical confirm, but 1 + to-hit >= AC, does the attack crit?

No.

The critical confirm roll follows all the same rules as the original attack roll, including automatic success or failure on a natural 20 or 1.
