The moment Ikaiel unleashed his skill, Erix's supreme crown shone as he remained supreme till this moment and reached 300k in stats, surpassing Ikaiel's stats.
And in the next moment after Erix's eyes laid on the incoming violet maw from a mirage that formed from Ikaiel's hand-claws coming at him, he created his makeshift skill in Mind Zone.
The analysis from him was done. The incoming attack was based on an exotic element of Death + Flame + Lightning along with a refined design of powers by Aethir's attributes. Soul Vices was impossible to know, but it was considerably powered by soul force as well.
And Erix wanted to defeat this attack and kill Ikaiel with his skill, and created that skill, imprinting its blueprint structure with his imagination in his mind zone and instantly designing the skill, including even its Soul Vices based on the most optimum conditions of this battle to win this bout against himself to reign Supreme.
