Augustus knew that he needed to be harsh in order to knock Ronan out. Not only that, he had to avoid his stray golden lightning attacks.
However, he seriously underestimated the capabilities of his grandson, as he could not even get close to Ronan, much less find an opening to attack him.
Every time Augustus tried to close in on Ronan, he would release a burst of golden thunder that would force Augustus back.
Had it been any other opponent, Augustus would have used his fire to burn them to the ashes by now. However, it was his lovely boy who was fighting him, hence he had no idea about how to tackle the situation.
He could not use long range attacks, while Ronan would not let him reach close range.
"Die…die…die…" said Ronan in a voice that was not his own, as Augustus's heart sank even further. However, his resolve strengthened.
