It's from no book, it's just a logical assumption that you go from a ring of counterspelling to a ring of infinite counterspelling. It does the same thing as a ring of counterspelling, but times infinity. It is a pretty big assumption, and i can change this to just say: This armor makes you immune to the following spells, as per the greater spell immunity spell.
