Bay was spot on, good for him.

"Oh! Hey! Look!" Lex said, pointing to the smoke as it began to rise. "I...I think we did it! The Professor said this stuff's meant to burn right off or something, yeah?"

If the smoke was anything to go off of then she would say they were on the right track about now. Burning rune. Yes. The Prefect watched the smoke rise for a moment, wanting it weakened enough, in case that's how this thing worked and patience was needed or something then she took aim at the wand. "This being a simple ward, we don't have any other weak spots to look out for. You might wanna step back just in case."

This was by far her favourite curse but it was vastly underused. Blow up some things on the school grounds once and suddenly you're the bad guy. Go figure. "Expulso!" And a surge of anticipation for the wall to explode and crumple.
