Very short question on Communion Master and the slave matrix

The base cost is divided up equally and then dealt with seperately by each member of the circle. Modifications for skill level (including the master's boosted skill), encumberence, and gem use are all applied at the individual level. This means each member has to pay for his own armor, so to speak.

THank you.
The master's booster skill only comes in at the individual level? Oh no, I didnt know that. That's why my slaves are having such a hard time. Ok the spell is not quite the bargain I had thought.
I had thought: Spell X which causes Y fatiuge, requiring Q levels, would cost my Master and my slaves less fatiuge because my master is casting it at Q+3 levels, thus the slaves would have less burden to bear? <-- is that wrong?
Does thank
