Adam had been aware of the sudden surge of energy from the very beginning.
But someone reacted even faster than him – John, who had been lingering at the edge of the battlefield.
The moment Karthus lifted his skull-headed wand, John knew that Karthus was ready to go all out.
As a Necromancer, his strongest suit naturally lay in summoning skills.
Evidently frustrated by the continuous setbacks in the battle, Karthus now seemed ready to throw caution to the wind.
Karthus revealed a ferocious smile, reversing the position of his wand to press it against his own forehead.
A series of obscure and difficult incantations spilled from his lips, as the sky above suddenly darkened.
A chilling wind howled, carrying with it the scent of withering life.
It seemed as if an immensely powerful entity was about to descend.
"Feel the true wrath of a Devil! Even if it costs me dearly, I will make sure you remain here forever!" Karthus's sinister laughter echoed through the valley.
