[Repost] 8th Floor Theories Elaboration

was there a theory about the old bosses of nazarick being the 8th floor hierarchy based on the fact that one of the old bosses matched a description or something? something regarding a white bat?

That theory exists. The old boss in question is mentioned in the WN Katze Massacre as a 'luminous being' which some believe alludes to details brought up in the PRologue of something on the former 6th and now 8th Floor 'wilderness'/'wasteland' floor.

The logic for why the beings on the 8th floor are the former bosses is basically, Ainz Ooal Gown cheesed the system. IE every boss gets stronger as you encounter them. So if you encounter them all at the same time...... they all reach Phase 5 simultaneously. This is in addition to the infinite spawning army of NPCs that were the original gimmick of the 8th Floor. So it becomes a boss battle with every 6 Man raid boss buffed to the peak, with the support of infinite spawning jobbers combining all the worse boss types at once (you are facing super strong bosses fighting together with MOBs making sure you can't abuse action economy).

The support here is Aureole as a Commander basically amkes the army AND the bosses stronger as well, Victim makes sure the enemies wipes without even getting a change to learn how to pick off each boss, and Rubedo makes sure no one really strong can coast on their min maxed builds.

The challenge here is all the threats combined. Now it seems to achieve this, AOG made a penalty of some sort, as this costs gold to utilize. What part remains in question, but it's thtought the infinite spawning MOBs are billed to Ainz Ooal Gown' sTreasury automatically so they dont get to use that trap for free like the original dungeon.

Others think the gold is required to 'activate' the bosses on the same floor.

That's all just theories but it seems to make sense with the features we know of.

Now if that is what the 8th floor beings relaly are or how it works does remain in doubt still but that's the addendum to the theory that you brought up as it reaches it's natural conclusion.
