Was the purple energy coming out of the Elf Demonoid's hand magic? Yes. Did he know anything about Witchers? No. Why would he bother, learning about what creatures so insignificant as humans did with their meager short existences? They were bugs scuttling about on the lower levels of creation, crawling on their bellies for any spare morsel they could grab. They were nothing. Mere tools, no, they were not even tools. Tools had uses, they were pawns. Nothing more than sacrificial pieces of garbage to use as he saw fit. So, he was nothing if not surprised, when this lad had something more to offer than normal weaponry. He was stunned with his usage of magic to reflect him, and as he aimed to claw him asunder with magic and physical force, he was not prepared. There was no defense prepared and none he could have erected. Full Counter, what did that even mean? Well, he was soon let know, was all the magical force he was going to use to rip this lad's head from his torso, was directed up his arms. They were sheared from his very shoulders the extra pressure spreading across his torso after there was no where else for it to go. His body flew backwards and he looked up at the sky. He was dying? Being killed by an insignificant little human over a bard and some farm animals. "Ugh!" blood spurted from his mouth as he tried to speak, and the demonic presence within his person screamed, trying to force his body into movement, trying to tear him apart, lest he be carried into death with this body he possessed. But alas, it'd all happened too soon. The convulsions continued for a moment or two and then... he was nothing more.
"That was pretty bad ass! Nice job, Nii-san!" the Demi-human girl said. She and Jaskier were now visible again, both had watched this epic unfold and both were more than satisfied with the outcome of it. "Thank you, thank you... you saved my life!" Jaskier proclaimed as he moved forward to his now broken lute. There was obviously nothing which could be done about this. He'd need another, though he had no way of making the money necessary to replace it. He looked at the broken bits of wood and string with much sadness in his heart.
