Continue to the right, defeat the enemies in the courtyard, and find materials inside the first floor of the dilapidated house nearby.
After obtaining this material, head outside and look to the right. You'll see two climbable spots; climb up to the mountaintop.
After climbing up, you'll encounter a barricade ahead. Break it with your axe to enter the cave. On the left side of the cave, you can collect some Dust once combat ends.
Follow the cave path inward, defeating enemies along the way, until you reach a save point. There is Dust on the stairs nearby.
There is also Dust next to the Buddha statue on the left side of the save point.
Save your progress and proceed down this path.
Heading forward will lead you out of the cave. There are three items to collect outside.
The treasure chest contains the support accessory "Divine Mechanism Ring".
