Go fight muddites in beholder. You'll find a pretty damn good use for
cure blindness real quick. Not to mention any other time one of your
party members gets blinded. Or.. If you yourself get blinded while
soloing it kinda puts a kink in your gameplan. Not being able to see
what's going on can cost you your life. As with a few other cure
spells, it sometimes has to be cast more than once to be effective.
