Johnathan took a step back as Valerie was damaged and he was kicked. No matter. He'd have her repaired. The armor absorbed most of the brute force of the blow, which meant that Magnus wasn't dealing much damage. Using claws, the only way he could kill Johnathan was with a blow to the neck. However, Johnathan was at least a foot taller than his opponent, and his neck was well-protected. Magnus wasn't equipped for fighting vampires, and he was. This was his main advantage in vampire vs vampire battles. Few vampires know how to wield the weapons that can kill them.
Moving forward, Johnathan seemed to punch towards Magnus. However, instead, he fired a shot from Justice, the shotgun in his right arm, literring the area with holy shot. The bullets were small, but they were hollow-points filled with holy vapour. They would cause an explosive shockwave on impact, and spread the burning gas inside of Magnus with each hit. Furthermore, the spray of bullets meant no aiming or accuracy was needed whatsoever. Furthermore, the fog was beginning to roll in, having been given plenty of time to reach this area, and once it engulfed the arena, Johnathan knew for a fact he would be victorious.
