Some questions about solar brilliance

I have been reading through the forums about this spell but I would like to have everything clear :-)

Let's see then...

The spell causes 700 fatigue... do I need a communion to cast it or may I cast it with a single arch theurg?

100 fatigue in a spell means that it needs a gem. 700 fatigue means it needs 7 gems. It's part of the game mechanic. So one Theurg powerful enough to do it will be enough.

Is there anyway I may protect my troops from blindness?

Does the spell have "magic resistance negates"? If so, yes, if not, then no. I forgot. I've used it only a couple times with R'lyeh's Void Lord who does not have eyes to blind anyway.
