"Not everything. The Reparo charm does not seem to work on objects of powerful and complex magic." Hermione notes softly.

"Charms is one of the first thing wizards are taught in my world. Charms adds certain properties to an object or creature. And as you learn and master charms... you can adapt the charm itself. Or start casting hexes."

"When we come to Transfiguring, it becomes more complex. A transfiguring spell can change an object or creature into something utterly different." Hermione knows how strange it might sound. "We change reality itself with our magic."
