Diamantona's bulging eyes fixed on Rex in utter frustration.
He never expected things to escalate this much.
First, Rex somehow had another form that changed his battle style completely, making it harder for him to be read. Next, he somehow has the ability to cheat death multiple times, which made killing him ten times harder. And as if that wasn't enough, he used an uncanny method to push his immortal energy to a new height.
A Demigod's immortal energy couldn't be boosted.
It was something that one would need to earn slowly through their associated God.
Many spent centuries of effort only to get crumbs from their associated God.
Rex, on the other hand, had increased his immortal energy so much in a matter of days, and he also has the ability to amplify it. He went from barely someone who could threaten Diamantona to someone who surpassed Diamantona in raw immortal energy.
Had someone told Diamantona that Rex would surpass his immortal energy, he would've laughed.
