Q; Regarding Communion Master/Slaves

[thekossack]

When playing as Pythium, I notice that after casting Communion Master with many communion slaves, my Theurg doesn't show an increase in magic levels when I click him for his stats display. In the game, when mages cast level gain spells, the new level does show on the display, so what gives about communion master? Is he buffed and not simply not showing? Is it a bug? Am I supposed to do something specific for the slaves?

Also, when my Theurgs are buffed but set to simply cast spells, they tend to be very stupid, casting nothing but Body Ethereal again and again. Whats that all about?
