That one Presley had to think about really hard. It was a first year level potion, and because of that she hadn't thought to study it at all. She hadn't given the potion a single thought in like four years. She danced into the first steps of the variation, closed her eyes, and thought hard for a second. "Healing potion." she remembered. "It can wake someone from magically induced sleep or coma. Historical uses include...." She didn't know. What were the historical uses. They'd covered this in potions, and it was sure to be on the exam. She sighed and her eyes opened, though her body never paused in the dance. "I don't know. Give them to me." They'd be written somewhere in the book, so if Befelda didn't know them either, she could at least read them off.
