He attacked before the skeletons could begin to fall, sending a blast of darkness in the back. The dragon zombie preferred to conjure them up and spit them out like a breath, but could still release them from any part of the body.
Treevor acted quickly, using earth magic to transform the piece of earth that teleported along with them into a floating platform, before all the skeletons kicked the platform to deflect the breath of darkness.
As the only one able to move in the air, Athos was naturally the first to attack. He did a somersault in the air and conjured an air platform while upside down, before kicking it and diving with his sword aimed at the dragon's weak spot.
Athos even used lightning impulse with his body and mind, both abilities enhancing his speed. The distance between him and the dragon was just over 10 meters and Athos crossed it in a second, looking like a silver flash to everyone watching from the outside.
