The Gryffindor boy, the Slytherin girl, and the Ravenclaw girl all put up counter attacks for the masked figure. He watched through the slits of the mask as fire and sparks came his way all at once. He stumbled back while trying to avoid the attacks, only managing to avoid the Gryffindor boy's attack, by the skin of his teeth at that. Flames dances at his feet while he found himself jutting out a couple of sneezes. It was becoming an annoying situation and he couldn't fight like this. The masked figure hardly recovered in time to avoid a free shot against himself, but he managed it.
Can you not fight better than this?
Master's harsh judgement came through and he gritted his teeth. The masked boy knew he would be punished but this was the only way to win. Witnesses could be killed if required. His wand moved up quickly and he tapped the center of the mask. An almost holographic transition took place as the black mask began to vanish. The boy pulled down his hood and shook off the recent damage he had taken. Now he could see, feel, and move freely. No more handicap. This was a fight he could not afford to lose.
"They will not stop me." He nearly shouted back at the voice in his head before turning his focus onto the Slytherin girl. "You think you know anything about us? You know... nothing!"
Now that he was free and had revealed his face, it was time for action. He pointed his wand at the Slytherin girl again with renewed vigor. She would go down whether he won or not. He would be SURE of it. Her rude attitude made it easier for the Master to command him. He still maintained an overall defensive stance to help avoid attacks, but not the most extreme version of it. With his wand renewed onto Marcia he yelled out a different spell this time while slashing his wand like a sword. "Diffindo!"
Now the masked figure was revealed.
Action: Diffindo at Marcia - Defensive Stance
Summary: Marcia hit for over half her HP. Parcelsus misses. Marcia and Delilah hit the masked figure.
