Taking her seat on her mat and spreading out her notes on kappas, Kurumi promptly shifted her body into the lotus position and began to focus on her breathing. They could just stay in this position the entire lesson and she would be fine with that. It wasn't too distracting and rather easy.

Flipping through some of her parchments, Kurumi found the one where she had made a few notes on possible spells and raised her hand. "I'm doing my final on kappas," Kurumi said as she returned her hands to her lap. "Besides spells to immobilize and stun the creature, there are two possibilities I thought of which sort of directly relate to how you can defend yourself against them. However, one of the possibilities breaks Gramps Law of Elemental Transfiguration, conjuring a cucumber, so there really is only one other option. Since kappas get their power and strength from the water-filled hollow on top of head, you could perform a Hot-Air Charm or a Drying Charm to make the water evaporate."

There was also using an Unforgivable on it to force it to bow and make all the water pour out of the impression on his head...but that wasn't something the Gryffindor wanted to voice out loud.
