Even though the Tyrant of Destruction had been severely injured, he gained a tremendous enhancement in strength thanks to the Blood Eclipse Moon that was shining high above the Colosseum's arena.
That way, it was possible for him to fight a little bit longer against the Undying before he would be finally defeated.
The crimson moonlight of the Blood Eclipse Moon enhanced the might of Nial and his subordinates, while Dilan noticed some negative effects that began to affect him after some time passed.
Despite the effects of the Blood Eclipse Moon that affected everyone in the arena, particularly adversely to the Undying, he had been able to defeat Tyrant of Destruction.
