There was also the issue of trying to cast offensive spells. The only thing she had been able to cast properly was Sectumsempra which had been weakened to a strength that was below a properly placed Diffindo, not to mention that while the curse cast three slashes to appear on her target, she couldn't aim where the marks would land at all - not to mention she could only cast spells she knew the incantation to. Wordless magic was not an option with the new state of her wand, but she was relieved she found the second tracking charm that Draco placed on the map.
