There was a green light that covered Baron's entire Cerberus form like his own skin. The light cracked and then shattered after Gina dealt her final attack. This surprised everyone as Glenn launched the two that were only waiting for the signal.
"Finally, I can attack," John grinned. "Let's see what you got, Anthony. Rising Carats!"
Anthony smirked and shook his head in amusement. "Fine, let me show you. Burninh Strike!"
The two of them spun and launched their attack when the final piece of the green light around Baron was shattered. Their attacks became much more powerful because Baron lost his shield and his HP dropped significantly.
"The hidden secert of Cerberus," Glenn sighed. "Everytime its HP drops to around ten to twelve percent, it would enter its vulnerable state. Its defenses would significantly drop and its regeneration would not work properly, it was the biggest flaw in the Cerberus's design.
