"I've done some research, but I'm not sure how much of it is accurate," he admitted. "Most textbooks don't always mention the person who came up with the spell, or how much trial and error was involved, if they were purposefully creating it. It's much more likely to discuss it if the spell was created by an accident, particularly if it ended horribly." He shrugged, with his hands still tucked away in his pockets.

"Mostly I'm unsure if it would be a productive use of my time," he said finally.
