- Enter the cave and follow the main cavern route toward its branching ledges.
- Check the marked Ferrystone pickup among the cave’s fixed chests and ground items.
- Collect the item and confirm it appears in your inventory.
- Continue through nearby branches only if you need other cave loot or exploration progress.

- Entering the cave expecting every chest to contain a Ferrystone; follow the marked pickup.
- Planning a return farm after collecting the item; move to another resource instead.
- Trying to travel before reaching open sky; use the Ferrystone outside the cave.
When to stop or switch
