Tip: Counter to Darkness?

[Gregstrom]

As a footnote:

The AI is apparently reluctant to cast Solar Brilliance against Mandaha darkness, even when scripted

I can see a few options:

1 - The AI has a weakness in this area.
2 - Solar Brilliance and Darkness are actually mutually exclusive in the sense that once one has been cast the other cannot ba cast over it.
3 - Mandaha Darkness is special in that (as per the unit flavour text) you specifically cannot cast Solar Brilliance against it.

Any thoughts?

I know for a fact that solar brilliance does indeed cancel out darkness. I've had it cast against me, and seen it work. That said, this darkness was the kind cast by Ermor.
