Imperious Bloodline 13th level spell

[Expostfacto]

I was looking into the Imperious Bloodline since a player for a future campaign was considering playing one and I'm trying to figure out what pure strain is.

Does anyone know what book it is?

It's a misprint. They scrapped the spell before the book was released, but the bloodline didn't get fixed. I don't have a link, but I know one of the devs commented on it. Fire up the old search-fu and you should find it.
