Lia raised her staff into the air, and the temperature dropped immediately.
A massive magic circle formed under her feet and spread out until it almost reached the students who were standing.
She turned around and looked at Silva. "Brother Silva, please try to attack me in the circle," she said.
Silva could tell what would happen if he stepped into that place, but for the sake of the presentation, he charged into the circle.
Immediately he entered, five massive ice lances formed and fired at him. He quickly dodged all of them, but as soon as that round finished, another five fired at him.
He kept trying to dodge until he had to step out of the circle, and the attacks stopped.
His presentation might not have been the flashiest, but it was without a doubt the best that had been shown up until now.
