Lesson Four: Using the Switching Spell (swap Slug for Snail)
Leif leaned on his desk as he waited for his students to arrive. Today's lesson material was interesting, took more effort than switching quills had done last week. He did wonder if any of his students would be repelled by the slugs. Once everyone had taken their seat he waved his wand to close the door.
"For today's lesson, we will be learning cross-species switches." Leif started, looking around the room to observe his students' faces. "You worked with small inanimate items last week, but I'd like to move on to something doubly as challenging. First," He pulled a rather large terrarium full of slugs from under his desk. "We will use living creatures rather than small items as our subjects. Second, we will switch them with snails, which are very similar in both appearance and complexity. Cross-species switches occur when a wizard takes one animal and swaps it out for another. Understand? Good. Remember that you don't need to know the exact location of what you are switching the two with."
"Use the same technique you employed in the last lesson to swap your slugs and snails. You all recall it's non-verbal, right?" The class nodded slightly and murmured to themselves. "Complex, but not impossible. If you cast it properly, your slug will seem to grow its own shell, just like it would with a regular transfiguration spell. You and I both know, however, what is really taking place. It might take a few tries, but I've no doubt you will be able to pull off the spell effectively. Take a slug, and get started. If you need me, don't hesitate to yell out." Leif watched as his students came up to the desk to take a slug, some more stoically than others. Once everyone had theirs he got up to move around, observing their work and lending a helping hand every now and then.
Roleplay attempting to turn a slug into a snail for full marks.
