Taqwus,
thank you for telling me that Communicants will help with priestly magic, too, I have not realised this till now, since I have never tried it in combination with a priest
I have used them to empower my mages fairly often, but tend to only do this when I have advanced my research fairly high.
I think once I reach construction 7 or 8 (forge of the ancients/high level artifacts) I will send some of my star children out to support my mages/priests.
Thank you again for helping me to learn this game
