Couldn‘t some of the True Dragon lords also beat the entire 8th Floor? I mean for example if Cure Elim Los Malvar would use his [Soulbreakerbreath] on the 8th Floor Hierachy including Rubedo, wouldn‘t it kill them all permanently if the World class item there would be not in their possesion anymore? There is no way to dodge or to resist this beam unless you can use Wild magic or you are in possession of a World class item. Also for example if Platinium Dragon Lord would use his indestructable [World Seperating wall] to isolate them like for himself to buy time or If he could also perform some similar barrier only around himself as some kind of armor and shield and still attack in this state, wouldn‘t he become completely unbeatable and is there then any possible imaginable way to beat him without Wild magic or World class items? He is also capable of an hige exposionspell which is apparently able to ignore item based immunities. Like in the Web Novel when Shalltear as a vampire weak to fire damage received fire damage due to immunity. Could Ainz maybe somehow bypass or resist somehow such things with his [Wish upon a star] spell or a skill of a World Champion like Touch Me or some other until now unused spell, skill or whatever? We know that the Eight Greed Kings did battle with the Dragon Lords and won, but only because they resurrectioned themself with Cash shop items repeatedly and probably used armies. Most likely they did also not face higher fatal Wild magic Spells like [Soulbreakerbreath], which makes such common resurrection impossible and only possible with World items. Of course Nazarick nearly endless forces would be in the end just be to much for them to handle because of their consumation of Souls (Healthbars), but wouldn’t there still be irretrievable and unpreventable damage?
