New empowerment strategy?

Does anyone consider it to be a viable strategy to start a pretender off with a lot or "3" ranks as a rainbow mage and then empower to 4 for purposes of getting all or almost all of the bless effects for sacred troops?

Also, has anyone ever found a blood magic site? I never did despite generally having blood 2 on my rainbow mage searcher. At least not in the sense that I would have a steady income of blood slaves or a blood summoning site that required fewer slaves to do something neat.

Final question...Castles only draw resources from provinces you control, right? Not adjacent enemy provinces?

Yes. They are very rare though...

Only your provinces.
