Communion and path boosting

[Yrkoon]

Hi,

I am playing a MA game with Pythium so I a going to use communion a lot. I was very lucky to find several magic sites that let me recruit indy mages (inverted tower for illusionist, crytal citadel for crystal mage, citadel of the iron order and academy of high magics) in the first 10 provinces or so that I conquered, and two of those can forge crystal matrixes.

I would like to know if during a communion, path boosting spells apply to the communion slaves, even is they do not have that path. And will the slaves get a corresponding reduction in fatigue when an air spell is cast by a master.

for example, will an illusionist casting storm power give a +1 to air magic to my theurg communicants (they do not have air magic to start with)?
