Confusion And Panic
The clone with the Mesmer system was being very helpful as his illusions could be cast on groups thanks to the huge difference in spiritual strength between Zavier and the mobs that he was fighting.
Zavier truly felt that he had done a good job keeping this clone safe. It had managed to progress a lot thanks to the constant efforts that it had put in. Moreover, the clone with the Mesmer system was someone that the mobs would never be able to grind down as it had a huge reservoir of spiritual strength and mana and all the spells and illusions it was casting required a very low amount of fuel to cast.
Therefore the clone was throwing spells and illusions everywhere without a care for the world and the enemies were terrified of what was happening. People were falling unconscious for no reason and amidst the commotion, no one had the calm to even check whether those who lay on the ground were still alive or not.
