[@LordOfTheNight]  Shiara is probably not going to be able to fight the Cursed the way the others do, not without a lot of training.  I would never make something that unbalances things -- if she does devise a ritual, you can bet it'll take long enough that everyone will need to do plenty of fighting to let her cast it.  And that's more a thing for down the road.  It just seems pointless to have her entire set of knowledge entirely useless.  If you have other ideas for her, I'd love to hear them.
