Once the movement was completed both of the blades vanished and a couple of seconds after that every grunt that was touched by them fell to the ground in two pieces.
Henrik looked beyond the barrier where the actual threat lay. The grunts were mere cannon fodder for him and since using the 'Beast Slaying Formation' put quite a toll on his body he needed to make it count.
