William and Surtr exchanged blows non-stop causing everything around them to be obliterated.
Perhaps knowing that his size wouldn't be a great advantage in his battle against the Half-Elf, Surtr decreased his size until he was only ten-meters tall.
Although he was still considered a Giant with his size, it was far smaller than his original height, preventing William from taking advantage of his blindspots.
"You've grown stronger," Surtr said after he and William distanced themselves from each other.
"Not strong enough," William replied.
After exchanging blows with Surtr, he clearly felt that the God of Destruction was still stronger than him. If they were to make a comparison, William's Rank was that of a Millenial Beast, while Surtr's rank was at the Peak of the Myriad Rank.
