don't think it was close, he almost 1HKO, I was even surprised he almost killed him with the 10th sword, even only lvl ~50 he already can survive peak legendary characters and probably defeat middle tier legendary ones
He is already so strong that I think if all players from the server try to kill him at the same time he could kill all of them and still have skills to kill some legendary powerhouses, and he is still lvl 50, imagine when he gets max level(probably will be between 80-100)
