((OOC: Ok, wtf? Does anybody else have a problem with how Aurora can run and fly with a broken leg?))
James realized that there was no point in avoiding the inevitible. "My apologies, Mr. Crowley. I suggest you leave now. Therefore, we may continue this confrontation with these... annoyances." James' kick was blocked, he was forced to use Protego three times too many, and now Mariana Diggory was throwing in her own spells. James' eyes returned to their own steely glare. Whatever spirit that had been left was gone now. There was limited options now. James clapped his hands, and pressed them against the ground. Four walls emerged from the ground to protect him from the attacks. When Mariana's Bombarda Maksima blew apart the four wall defense, James' arm was now in another strange form. The electrified blade was gone, and the hand was back. But there some new symbols on the hand.
The theory was simple. There was enough dust left in the air to hold an electric charge. This, in addition to the cataclysm needed to release that charge, would allow James to unleash long-distance electric charges. Not as safe as a simple Petrificus Totalus, but it would still be effective. He could not, however, afford to use a spell that would harm anyone beyond his target.
James let the electricity surge out just a bit, as he used the arm to guard his mouth from the Langlock curse. He was now pure business. He didn't need to speak, but there was no need to suffer the indignition of suffering due to the whelp's curse. James' eyes now centered on his younger quarry. The little Griffindor. She would not last long. James leaped straight at her, ducking low to avoid two flying curses. His arm snaked for her wand arm, grasping it in a vice grip. "Name." It was a demand. Not a question.
