"Yeah, I learned to put up a shield against snowballs." She smiled slightly at the memory. "It will work against weapons, or well anything projectile. To be honest, I haven't tried it against a knife attack, so I don't really know about that. I would assume it does, but I wouldn't bet my life on it."

Molly suddenly smiled, "but a knee to the balls works against that, so does veiling. You can't stab what you can't see."
