Sealing is Ebony and Ivory Based.
Its basic version is a unconventional power null + BFR.
Its strongest version also seals away target into Demon World.
Dante at this point uses the 2nd type.
His fear hax comes from haxxing V wh0 already have 4D emphatic and mind resistance.
Also note it can affect inanimate objects, so its got Versitility as well.
How the power null works? I mean, I've played only DMC3 so I really don't know much about Devil May Cry, but Ebony and Ivory there were shooting and just causing normal damage. And the sealing thing, are there any specific mechanisms for it? Because if it just teleports the Machine to another universe, it isn't helpful at all.
I'll already say that, personally, 4D mind/soulhax is something I severely disagree with. It really shouldn't be a thing.
In any case, assuming hax can be quantified like that, it still shouldn't affect the Dawn Machine. Entities such as the Machine aren't affected by similar powers either, with the Fear Manipulation of certain beings (Such as Mr. Eaten), that extend into the past, present and future, beyond the moment it was born, being very much below their concern. In fact, almost any Judgement can effectively have empathic and mental powers of such a level, but they typically simply do not work on each other.
I also decided to read the profiles, the demon physiology page and all that, and, unless Dante has a better feat for Law Resistance, he wouldn't really resist the Machine reordering reality. His resistance has the following justification: Upscales from
Demons came from the Demon World, a place that has different laws that exist upon reality compared to the Human World and when they decide to step into the Human World, they also don't need to follow the laws that exist upon that reality.
The problem is that, that kind of Resistance to Law Manipulation would only be useful against someone who could only manipulate the natural laws of the world, or that could only manipulate existing ones. In Fallen London, we have examples of beings like the Demons of DMC, who live in places that follow different laws from those of the world, and that do not need to abide by said laws when coming into them. Parabolans are like that, as are any inhabitants of the Neath. The latter are even shown to still operate under different laws of reality when compared to other humans when they go into a world without Judgements/Judgements that are on the very least tolerant of them.
Whenever any of these beings actually come into the reach of a Judgement that doesn't want them to Be, they are erased from existance. Judgements enforce the laws of the world: If they are confronted with something that do not work or obey said laws, said thing is simply erased to conform to the new standard.
So, unless Dante has other showings I am not aware of, I don't see his Law Resistance being particularly useful against the Dawn Machine.
