What happens when a Beholder is hit with a blindness spell?
a) it is blind, as per the 100% concealment rules, but can still fire its eye rays -- IF it manages the listen check and 50% miss chance.
b) only one of its eye stalks, or the central eye, is disabled; but the rest can still fire away until they are targeted as well.
c) the PC's high-five themselves for completely nullifying a powerful, high level monster with a 2nd level spell.
