The Force Orbs floated about, and they launched themselves toward her with the intention of causing physical pain. Caitlyn saw no need to allow that, and her body undulated the musculature within. Her crystalline body moved forth and her right and left hands slammed together at the center of her mass. The force of it resonated a crystal ringing sound - and the power flooded forth from her body. The void was not simply something of purification, something that immunized her to magical energies. It stored them, and now she unleashed some manner of it with the slamming of one hand against the other. 

The force of it resonated, dust flew forth from her body with concussion of her claps. The wind picked up, enough energy behind it that it could easily rip flesh from bone. Tearing muscles from limbs. The grinding force of it lashed out and the force orbs blew apart with the ferocity of the blow. If Preacher remained, his body would simply cease to exist. The blast would tear him to pieces, Caitlyn followed behind the blast, keeping pace with it. If Preacher stood there, and managed to survive the power of the blast itself without moving - she would be right behind it. 

Fist upraised, her body turned and tuned to deliver a crushing, devastating blow of his superpowered fist.
