Alternate domains book?

[Heretic Apostate]

I seem to remember there being a book out there that had, among other things which I now don't remember, alternate domains.

If I recall correctly, the d20 publisher switched out every even-level spell from a domain, thus creating an alternate domain with which to distinguish gods with similar domain lists.

But for the life of me, I don't remember what's the book's name...

Help?

That would be Quintessential Cleric, written by Sam Witt, published by Mongoose Publishing.
