The Vampire demons power

 At close range, Quinn had shot out a dark coloured blood aura directly at Kronker, it had smashed him in the chest throwing him to the ground. The blast was so large it had covered his whole body and one was unable to even see a single part of Kronker. 

This blast wasn't just any blast, as it had even used Kronker's own blood in the attack. It was clear that this attack was stronger than the blasts that had come from Quinn before. 

While the stream of energy continued to burst out from Quinn's mouth,  something else was happening. From his blood wings, small orbs looked to be dripping off. They were floating in the air just beneath. Droplets of blood from the wings were forming into something the same size as a football. 

When the blood ball had been fully formed, it moved, heading straight for where Kronker was. It crashed into the ground, causing a large explosion of power that reached up to the skies like a nuclear explosion.
