Ariadne was already thinking ahead and filing through the list of spells she was confident she could do. At the same time, she trying to think about what Jaemin might do, while at the same time watching to see what her spell resulted in.
THIS WAS A LOT OF STUFF TO DO.
Disappointingly, her first spell resulted in a successful shield on Jaemin's part. She kind of figured that one anyway. No student with any decent amount of dueling training would allow themselves to become covered in boils and pimples this early on in the duel. She might repeat that one a little later, though.
...and the spell he countered with was a BIG NOPE for her, too. Being stuck to the floor? Yeah, that'd be cool if she wanted to end the duel soon. As in...NOW. As it was, though, she'd cast the feather light charm on herself earlier in the duel, and she was moving was a much greater speed than she'd been moving in during her previous duels. She was super fast (in her opinion, at least) in raising her wand and protecting herself with a strong,
"Protego!"
Ariadne had already been thinking ahead and had a mental catalog of spells ready to go for when the timing was right. There was one she was particularly anxious to try out, and so she decided to go for it. It was actually her first go at this spell in the midst of a duel, but there HAD to be a first time for everything. Plus, it just might work out in her favor, so YEAH. Anyway...
"Ventus!" she called out, her wand waving about. The blast of air shot from her wand and began to blast its way forward. She doubted it was TOO strong, because she wasn't that experienced of a caster. She couldn't wait to see if it'd affect Jaemin, though!
