Someone said somewhere (not sure if on this site or animesuki) that Six Great Gods came before an expansion "Valkyrie" which probably increased the level cap. Could be wrong though. Should I put n/a? If you can give some sort of clue to their level then we can cross reference them to roughly estimate their level.

The Eight Greed King is pretty much good as it is since there are dragon lords to compare with but the Six Great Gods...uh uh.

The only clue I can think of now are the black seats of Black Scripture. In the WN, Clementine's rank is 9th seat. Clementine's level is 30+. Cedran which is 7th seat took an instakill shot from Shalltear so his level isn't far off from Clementine. But Shalltear mentioned the Captain of Black Scripture is much stronger than Solution Lv 57. That means the captain is around 60-65, perhaps near 70. If Zetsumei is the strongest member and no one can beat her with equipment then her level should be 70+ or perhaps 75+. Six Great Gods follow then which should be around 80+ because Zetsumei is a god kin. Well the last the part is really rough but everything up to Zetsumei should make some sense.
