There is still no clue to the further solution?
Hello, I also came through and have a letter, but no knife.
What does it look like please tell me and what is it for?
Hello. Unfortunately, I can’t clarify about the knife; mention of it was removed from the article. I don't have it either
I went through this quest and also don’t have a knife.
I recommend ing technical
What to do if the fifth grille does not open, I do everything according to the guide
After sequential activation, did you trigger the lever in the middle?
Yes, it doesn't work
I checked the sources, the article indicates the correct order. Try writing to technical
I couldn't find the knife
You brought the fairies, went to the upper underground floor, broke the vases there, and did not find the object? are you sure you didn't already have it? try writing to technical
I confirm the problem. Just finished the puzzle, but there is no knife on the upper underground floor, only an opened letter. I combed through all my inventory, alas :)
As a possible solution... have you talked to Teji on Yashiori?
I couldn't find the fairy and the knife 🙁
Are you sure you haven't seen the fairy before? which one is missing?
I did everything right, double-checked several times, broke all the vases, and looked for them for another five minutes, but the fairy and the knife do not appear
Are you sure you haven't collected them before? in the inventory in the "Letter opened" quest for Teji Toshi's son
Um, I did everything, gave the bloodflower, but nothing else happened, no letters from the fairy, nothing at all
the letter will appear if you break the vases on the level above
I found the letter, but what kind of discarded knife are we talking about? There is nothing like it in the inventory, and I can’t find information about it anywhere.
what do you mean you don’t know about the letter right now? the letter contains the name of the boy Choji, who was mine at the shrine in the jakoku mine, which had to be cleared in the future, he still sells bone marrow, so right now I’ll go check if it’s possible to give him the letter
unfortunately you can't give it away.
