Ooooh. He’d given her permission to work on larger shields. Goody. That must mean he understood how brilliant she was.

Okay, time to do it. She dropped her original shield, and recast, making sure to include the horizontal motion this time. “Protego”. Oh my God. She’d known that larger shields would take up more energy, but this was kind of ridiculous. After just a minute, her shield fell and acrons smacked into her once again. Great.

She cast a quick regular protego as something came to mind. She raised her hand. “Professor, I was just wondering. With the obvious amount of energy needed to cast a large protego shield, would it not be easier to cast a variant, such as protego totalum if you needed to protect a large area? From my understanding, that particular variant does not need to be maintained.”

While she waited for his answer, she attempted the dreaded large shield again. Upward arch, horizontal motion and wrist flick. “Protego.” She focused every ounce of energy and concentration she had into it and was pleased to see it lasting. For about two minutes. Eh, not great, but better than before. If there was a more efficient variable though, she would much prefer that one.
