We have no idea how many others are there.
Excuse me, but overgod is still a god

"Pandorym's stats"?
Gee, what stats?
Let me remind you: three biggest Elder Evils in the book - Atropus, Leviathan, and Pandorym - are have no listed stats!
(Because, if they're, actually, appeared - then you're already lost)
If by the "Pandorym's stats" you meant "Mind Shard of Pandorym" - then let me enlighten you: it's not the whole power of Pandorym; actually, it part is so infinitesimal to the "big whole" - Pandorym can have unlimited amount of Shards without becoming weaker in any notable manner

The "divinity nullification", while not stated directly, is strongly implied: Pandorym agreed to kill the gods.
And not just one or two - all the gods without exception.
To try it without having any means to negate their divinity is as stupid as hunting bears while being unable to put a bear down
And, judging by the fact gods were, actually, afraid - threat was completely real

Just as I said: answer without explanation - why killing the strongest "normal" god of the Multiverse (i. e. "strongest, but still no overgod") didn't caused Multiverse to fall apart?
