Khaston didn't wait and attacked Xandre with his fist filled with dark energy that would absorb all his power the moment he touched him. Knowing that Xandre immediately avoids his attacks. He knows that he can't be touched by him because it would be dangerous. But then, Khaston didn't stop there and created a sword from materializing his power.
Selling tried to control him but she could barely reach his mind. At this point it is hopeless. The sword is expanding, enabling Xandre to dodge. He was about to get hit by Khaston's sword when Yllse immediately swung her electric sword causing the two to ignite. But the thing that surprised Khaston was that his sword didn't immediately absorb her power.
Once Khaston's sword can stick to any object, it will not separate until it sucks all the power in it. But Yllsen immediately repelled the sword, enabling it to suck her power.
