Asteira looked at the professor as she gave her a look. What.. she was just simply asking out of either curiosity or future use. You never knew when you could use a spell to blind someone. Their were loads of reasons. Which none of them required getting into trouble. Trouble... not her. " Its not necessarily that i would specifically want to blind more than i need to blind them. It could be used as a defense sort of spell. If it blinds someone from attacking you...well the spell value has just increased. Besides it being a light and everything." she then gave her a small shrug." Which the fact that it doesnt blind people is good for torturing cousins." she added with a small smile. Their were plenty little brats running around in France that she could use it on. Annoying creatures that ran around during family gatherings tugging on her clothes and yelling so loudly that it made your ears bleed.
