I'm Lost, I have a spoiler related question

[ZeeFlo]

I'm in Uru Manor. I managed to defeat the 9 giant clouds at the end. Screw those btw. Being forced to use a detrimental pact for a single battle is BS. Had to look up a guide to find out I needed that pact for at least one of the 9. I saw a new ending which makes me think I've missed something. Don’t think I should explain it just in case I got the spoiler tags wrong. Anyway, it feels too unfinished. Also, Boklin or whatever his name is on the 7th floor of Narthex is still in the way. So, I know there is something there. I didn’t get a clear game save after the credits either which is pretty apparent message to me that I missed important stuff.

I'm not sure if the remaining Memos have anything to do with my issue.
Ear for Rumors, Holy Cuisine, and The Sky is Blood Red.

My steam achievements list also leads me to believe I'm missing Curios too.
Madara Giant Fire Lizard Egg, and Star Emperor’s Stuff

So, my question is the following: Am I being held up by the Curios or the Memos. As a side question do I have to fight the 9 Clouds again after I collect them.

If it’s the Memos, I’m not bothering. I spent 5 hours fighting through RNG and had one Chocolate Acorn to my name.

As for the Curios…I’m curious about where they are…I felt like I was pretty through for not using a guide till Uru Manor.

I probably won’t bother if I have to fight those 9 clouds again. Took me too long since I didn’t have the right weapons with a vague extra effect anymore…apparently.

You do not need to do the requests, but you do need to collect all of the Curios, and then you will need to beat the Discordance again. One of the ones you're missing is in Apse 1, the other is in Yellow Transept 2.

There are quite a few weapons with the Mysterious Erosion effect, so I'd be very surprised if you somehow got rid of all of them. There's a complete list here: https://gamefaqs.gamespot.com/switch/329530-labyrinth-of-galleria-the-moon-society/faqs/80172/discordance-gear-hunt

I feel dumb for missing the one in the Aspe 1 . I remember seeing it about 30ish hours in and couldn't see how to get it... and then forgot about it. I should have made a note on the map to remind me.

The other one I don't think I would have found without a guide. I never thought to break the walls in that area.

I found three in my sealed items. A hammer, a lamp, and a bell. With my puppet setup the only viable one was the hammer. It did a bit over triple the damage of anything else I was using. It didn't win it for me but it cut down the amount of time I spent considerably. I'm still not sure how someone would beat that thing on Nightmare. I barely skirted by on Gentle and probably would have failed on Ordinary.

I think I'm just bad at setting up teams of puppets. I'll have to look into it when I trying pushing into this new area.

Thank you for the help and the link.
