Impedimenta was the first charm that came to Sophie's mind. She raised her hand prepared to suggest it, when Adi beat her to it She frowned and lowered her hand as her classmates continued to suggest more and more charms. Most of her other ideas were already taken by now, so Sophie had just about given up on coming up with something new, until finally a charm popped into her mind.

"What about the Containment Charm?" she asked, raising her hand. "It's used to contain something in an object, and I've heard it's useful in getting away from an attacker."
