Solar Brilliance - resitant units
 

I am exploring possibility of effectively using spell Solar Brilliance. To do that I will most probably need units, which are resistant to the effect (I don't mind if caster gets blind). As far as I understand this, such a unit should be non-undead, non-demon, without eyes or effective even blind. Can you point me some of such a units, that can be easily summoned?

Thanks
