Can a Mage be Both Communion Slave *and* Master?

I'll be interested in seeing the results of that test, Yrkoon.
I was pretty sure it didn't work that way. I'd thought that having a master cast spells from a path the slaves didn't have was a quick way to kill off the slaves.

I am 99% sure slaves do not get a boost from the master's booster spells towards casting their own spells, if they do not have the path in question, even if the boost applies to reducing fatigue from the master's spells.

Still curious whether side effects of the boosters, like Earth powers reinvig apply to slaves with the path.
