stuck at Izumo rest arena

[Matt]

Hey there, I have been stuck in Izumo rest arena for 2 days now without knowing what to do, I got the quests "Miasma cleanup operation and it says Honomusubi Cavern Clear" And second quest "Talk to the knowledgable Haniwa" Where I have to clear it on hard, but when I try to go in it says "The miasma's to thick....we can't go in there. if we had something to block the miasma, it would be different story..." Can anyone tell me how to unlock all those dungions? thx

wear the purity magatama

Those are two different quests. The Miasma clean up operation is part of the mainline while the one that need to be cleared on the hard difficulty is given by the guest character Sheryl.
Also, do you have the Purity Magatama you crafted before? You need to have it equipped before you can access the dungeons you need to finish for the mainline quests. (Oonaobi Shrine is one of those dungeons and it's the dungeon you need to clear on Hard difficulty for Sheryl's quest)

I suggest you finish all the dungeons that is mentioned within the mainline first since I'm not sure if you're guaranteed to have access to Oonaobi Shrine even if you have the magatama equipped.

Just making sure, but are you sure that that's the dungeon you're meant to be entering atm? You have to do them in order.
