Revertoscutum..that sounded like one of the transfiguration spells to turn your pet into a goblet. Only that was just 'Reverto' with three taps against the pet. Transfiguration was one of her favorites to read about. She wrote notes about the spell before attempting it, "Revertoscutum!" she casted causing a weak blueish shield to appear in front of her. She forgot one of the most important parts of transfiguration and DADA, focus on what you want and what it was supposed to do. "Revertoscutum!" she stated thinking of a shield appearing in front of her her wand pointing in front of her. A stronger blue green shield appeared in front of her. She nodded proudly dropping the shield writting it in her notes as well. She saw the spell turned into different colors, blueish green the most common with some light blues to a royal blue. What one said it was the strongest? She'd think it would be royal blue but who knows the Professor will tell them soon she thought.
