The shield had been thrown up in a moment of reaction and was not as sturdy as it should be. Her wand was wrenched out of her hand, though it did not fly quite as far as it would have had the shield not been there at all. The searing pain subsided and it took her a few seconds to completely reorient herself.
There was a fire in her eyes, and she wanted nothing more than to hex him and yell curses, but she could do neither as she currently could not speak nor did she have her wand. She instead took a few steps forward, ready to fight with her fists if she could get close enough. The difference in their heights did not deter her. At the very least, at least maybe she would be able to get close enough to reclaim her wand.
