Rudra took on the knight of the emperor form and began his counterattack against four tier 5 enemies at once.
Rudra knew that the only way to ensure that the enemies actively engaged with him in battle and not try to run away was if he started to deal incredible amounts of damage to the city and to the devil's army, which was why Rudra chose to go for the giant form for this battle.
The knight of the empire took massive amounts of MP to mentain however it had unparalleled PVE abilities , especially now that he had Excalibur.
Excalibur was extended until it became a sword worthy of being wielded by a giant and Rudra used it to unleash powerful slashes that could wipe entire sectors of the city , causing massive enemy casualties and forcing the tier 5 commanders to personally jump into action.
