"Oh, now that is dangerous. You are using some dangerous energy." The demon laughed a little as it moved to the side and tapped the spear with its finger. This forced Clark's attack downwards and forced him to use even more energy to stop himself from slamming in to the ground.
When he looked back, the demon was standing with his hands behind his back. There was a vicious sharp toothed smile on his face. He knew he had been stronger. Knew that the attack was something he could deal with.
As the demon raised his hands, Clark was prepared to attack again. "You try so hard, but I can't be hurt. None of you have that strength. I am an almighty being to you. And this isn't even my main body. Just a small piece I sent here. How sad."
Creation is hard, cheer me up!
