After obtaining this accessory, turn back and jump down from the side here.
Defeating the enemies downstream of the waterfall will yield plenty of Dust and a Transit Charm.
After getting the item, climb back up the wall where we came down, then continue along the main path. Keep going until you see the new save point.
The main road to the right of the save point is blocked by red threads. Use the chain to cross to the other side, and grab the Dust below while you're at it.
There are quite a few enemies here as well. Defeat them and pick up the nearby items.
The green item below is a collectible book: [Villager Relic Investigation #3: Villager's IOU].
