'Mighty Combustion has already evolved once and the chances of its evolution will be low. Moreover, it focuses mostly on dealing the high damage. Even if it evolved, I don't think it will be enough to kill the level 9 supreme-ranked heroes.'

Leo started eliminating one talent after another and in the end, he was left with two talents that could increase his survival rate.
Compared to the ability to kill the peak supreme-ranked heroes, Leo felt it was much easier to focus on the talents that could help him survive the attacks of the peak supreme-ranked heroes.
Spatial Manipulation could already help him survive against most of the supreme-ranked heroes except for those who could use the spirit attacks.
