What can Darkseid do to kill him? Dark Schnieder has the most ridiculous healing factor ever, and his immunities are incredible. The Judas pain makes him immune to reality warping, he can regenerate extremely quickly so long as even one of his eternal atoms still exist and they exist on three seperate plains of reality, and his are incredibly strong and go definitely take down Darkseid. C'mon Dark Schnieder fights Archangels on equal ground, Darkseid isn't enough to take him.
2 things. 1 schnieder has to preform an incantation for most of his stronger spells i don't think he'll have time for that, 2 while powerful i don't think he can channel as much power as DS can at once

Dark Schnieder can doesn't really have that issue, take a look at the description of dispel bound. He's constantly creating and reinforcing millions of shields at once to handle all possibl types of attack while at the same time tearing down his opponents defenses. There is no way DarkSeid can stop him from using his spells. Plus add in the fact that even Darshu's lower level fire attack tops Supes heat vision and I'd say this is in the bag.
