Jack continued to kill more magic users as he moved at high speed, just like a wolf in a hen pen. He saw the melee group coming over to rescue their comrades, led by the Golden Knight from before. Several Rogues had also now joined the fray.
Jack presented them with another Disruptive bomb. Some of them managed to evade to one side, especially the Rangers and Rogues, using their Roll skill, only to be met by another Disruptive Bomb. The two bombs completely immobilized those melee troops.
The stop effect of Disruptive Bombs was only 2 seconds, so in actuality, Jack did not have much time. He did not waste this short time killing the Fighters who had more HP. He instead, chose to dive onto the Rangers and Rogues, who required fewer hits to kill. And after the damage from the bomb, he only needed one hit to kill those Rangers and Rogues who survived.
