The Five-Force Push was a magic spell that possess the power of five different magicians, it wouldn't be surprising to see the automaton defeated after receiving the full brunt of the attack.
The spell didn't have such grand effects like everyone would expect from a combination spell, not only was the spell silent but also extremely quick. The spell created a beam that followed the automaton even if it tried dodging, it was a spell that hunts a moving target.
"A beam that could bend and follow the target?" Wallace observed the fight interestingly. The particle beam that was being used in outerspace had always been in straight line. It would annihilate any obstruction and leave nothing behind.
The battle of innovation with regards to the particle beams would be it's size, destructibility, and the distance that it could reach.
