Is Bahamut big enough?

That's not the same keys, it's the twelve attempting to seal him. Y'shtola, Thanacred, Papalymo and Yda had to pray at the shrines for Louisoix to summon the twelve, the light rising from them was showing him that he could summon the twelve.

There's still a lot they could do, what if the keys contain monsters that drop items needed to weaken him, or we have to break them open to get something, of course there is the pray at them. SE could add them in so many ways.

I was what i was thinking! the keys summoned with prayers look nothing like the keys that fell from dalamud. they were like... impromptu artificial holy keys (I can't think of a better way to put it), but they were sort of a last minute type thing, which is probably why they failed. there is something about the ORIGINAL keys that's important
