Many say an A-class weapon can only severely injure a True Immortal when fired at close range and unexpectedly. However, from afar, they won't sustain much injury.
That, in a way, is true.
However, the question is, how can one get closer to a True Immortal and spend three seconds charging a laser gun to attack?
It is virtually impossible. To pull that off, one needs to be both strong and quick to make a decision, and to possess the ability to buy them enough time to charge the laser gun.
In most cases, a laser gun is used only when a team collaborates against the opponent. While some distract the True Immortals, the shooter prepares the gun.
However, Klaus merely jumped out of the void and pressed the trigger as if it were a toy gun. The moment the beam exploded, the redhead True Immortal saw death but couldn't do anything to escape its gaze.
