It was hard to figure maths in one's head when there were no variables to stick into the equation. Not that he absolutely needed variables, but Mo wanted to know how his weight and the hardness of his wand specifically interacted with the casting of this spell.

Maybe he'd go to the library after class to read up on the subject.

For now, though, his gargoyle demanded attention. Mo pulled the stone creature to the middle of his desk and propped his chin up on his hands. "Hello, Gargoyle. We're going to have a bit of fun today, but you're going to have to do your part," he whispered, tilting his head back and forth until the shadows on the gargoyle made it look like it was nodding along. Very agreeable little thing, wasn't it.

Now then, what was the incantation? "Piertotum Locomotor. Piertotum Locomotor." He repeated the incantation until it rolled easily off his tongue. Now then... what should he have his little gargoyle friend do? "Piertotum Locomotor," he directed the spell at the gargoyle this time. Something simple to start. "Yawn." Mo mimed yawning, and the gargoyle's tiny mouth opened and closed too. "Good. Jump. Jump again. Do a circle."

His gargoyle was a genius.
