The "time to end this" thing was in the cutscene after the fight, when Vergil inevitable goes DT Dante is says "it's just about time to settle this" and Vergil replies "that's right, c'mon" and then he DT's.I'm not saying this particular instance doesn't count to the narrative but it perfectly fits with Dante's regen not being affected by stamina.
That's why we go off of what is shown, if Kratos time manipulation resists hasn't been shown to resist the level of time manipulation that Dante has then it's fair to assume it will work on him.We can't ignore the possibility of Dante's time manipulation working on Kratos just because we don't know the level of time manipulation he can resist.
"
How did he escape?" He didn't seal himself, he stayed in the Human World sealing away various portals.
"
How did he escape his own sealing?" He didn't seal himself, only his power inside the Force Edge
"
why would Sparda lose power if he had those artifacts?" once again his main power source Sparda was used to seal the Demon World.
"
If Sparda only had 1/4 of his power and couldn't perform the seal alone, how could he protect all of them from Argosax while performing the seal if Argosax is equal to Mundus and the author states that Mundus is the most powerful being? All of this while they're all probably in hell." Bolded was never stated and according to DMC twitter chair Urizen was stronger than Mundus.Alternate universe Mundus from the DMC2 novel was stronger than Mundus and Argosax which base DMC2 Dante annihilates, but to answer your question and correct your points, Sparda sealing Argosax happened on Dumary Island and you're assuming Sparda had to protect them during the sealing process.No bout was mentioned and if there were one they likely weren't involved but too much interpretation and headcanon is involved to when all we know is that Sparda couldn't seal Argosax by himself so I would just leave it at that.
Correction, Dante has fought people comeparable and superior to him before and regenerated just as easily, Chen from the novels is one example who was stated to be superior to Dante and Dante and Vergil in the middle of DMC3 being stated and shown to be tired in worned out also proves the DMC5 incident to be an outlier or interpreted wrongly.
No universe shaking feat ever happened,
here's a blog showing feats which are all at the very least 2x above baseline 3A.
Not that that matters much here based off what I said.
