Wait so they needed to perform a charm on Flamsteed? Well some of them would be slightly dangerous. He scanned the whole list and saw he would choose Diffindo. He grinned and knew this would be fun. He might do it to the side or maybe on a piece of a board because he loves casting Diffindo. Now he needed to preform it in front of the class? Welp let's do this. He got up from his seat and went next.

He waved to the whole class and gulped. He hated public speaking. "Hi I am Kace Lecium...as some of you may know...and I will be performing the severing charm Diffindo. I am not going to do it on Professor Airey obviously because it would cause him pain. I am going to do it on this desk here..." he pointed to it near him and away from other students. "Don't worry headmistress I will repair it after.." he assured her. He got his wand at the ready and performed the charm with his wand movement of a down and up and a little flick on the end and said, "DIFFINDO!"

Then he saw the desk crack right in front of him. Huhh....success! He grinned to himself and wondered what the headmistress thought.
