shoulder is only dislocated from this impact

A flash of light suddenly burst from a nearby wall. It was some kind of spell that resembled
a laser beam. The instant Kamijou realized that, he twisted his body around and held up
his right hand.
Second, they had grown conceited. They were not up against a Saint or Magic God. They
had Imagine Breaker at their disposal, so Kamijou had assumed he could deflect any
attack spell as long he was not surrounded and over-saturated with attacks.
That had been a fundamental mistake.
The instant he received the attack, his right arm was knocked backwards.
The intense impact twisted the joint of his right shoulder and sent his entire body
spinning at least twice through the air.
