The battle seemed a little short, didn't it?
It really did.
With Existence supporting Damien, the Count was practically fated to die. There was nothing he could have done, and at every turn, nothing worked out for him.
His mana didn't listen to him, the atmosphere disallowed him from correcting his stance or balancing himself, and he was always open to Damien's attacks no matter what he did.
The battle was indeed short, because Count Verex was turned into a puppet who had no free will of his own.
But that didn't mean it was a quiet fight.
Damien did an insane amount of damage. It had to be remembered that the releasing of his aura alone razed tens of millions of kilometers of land to the ground.
Every time he struck the Count, massive gashes were made in the jungle's ecosystem.
