The game is over

Darius looked at the blackened remains on the ground and fell. Darius could no longer maintain his floating and was now on the ground on his knees panting. He had used every last bit of the mana reserves that he accumulated by sucking the blood of his citizens for the past few months. 

This was his final trump card, and he didn't really want to use it. But after battling with Kretos and watching him excitedly mow down his enslaved, Darius actually felt threatened. He knew that normal spells wouldn't cut it and using anything less than this big move Kretos might be able to evade. 

It was a good thing that he started this tournament distracting Kretos for some time, while he gathered mana by bloodsucking. Not only was he able to gather enough mana to use such a big spell, but he was able to fill a whole city with his enslaved.
