Without negative theology stuff, the next best thing the Root got was legitimately in Tier 1C since infinite isn’t exclusive to 1A although I could see it as possibly High 1C if we being generous with the interpretation.Neither of those scans are stacked infinities. Those are showing that for something to be infinite it needs a finite to compare and the Root isn't subjected to that. But that's not the same as infinitely higher dimensions.
Also didn’t do want to clog up the Root upgrade thread any more than necessary.
