@Angelic Demon1 Divine is everything that has to do with the astral, the infernal power is an astral power because it is at a level beyond the magic that a person could normally dominate.
When I call brutal it is potentially the most dangerous, difficult to master and at the same time the best due to its skill and destructive capacity.
@Heartz13 That theory could be affirmative and it is that all this is related to qualities that go beyond nuclear energy at light speed; which would be the quantum energy to give a destructive scale so large that it affects even our very universe. More than anything related to Apocalyptic Powers
I personally went more with Antimatter Manipulation and it is because its domination and having this power is significantly incomprehensible compared to the other powers because Antimatter is in the unknown and is capable of exerting such a great force that it destroys any thing built on a specific type of atom from there based on logic the chaotic radiation could arise.
Even so, it is not a very easy survey to answer because these powers go hand in hand at their own root, in addition to the fact that each one has lethal qualities at high levels
You could just manipulate a plane of existence to its destruction, killing billions of beings in that plane. Example destroying hell, heaven and maybe dimensions/planes like the 5th dimension.
