I have never cast Solar Brilliance in battle, but I have used the Forbidden Light
quite a bit. It certainly works, and as Teraswaerto said, the longer the battle
goes on, the more troops go blind. A few times, by mistake, I had troops in
battles that the Forbidden Light's carrier won, and about 50% of the troops went
blind. It harder to tell what it did to the enemy, as they did not survive to
be counted :-)

As far as I am concerned, the spell is not worth using, unless your own troops
are blind to start with. As for the Forbidden Light, it is a great artifact that
I always try to stick on a SC.
