Before you go

- Have access to the required exploration progress for the Riddle of Rumination.
- Bring the item or preparation needed for the riddle’s completion.
Farming steps
- Progress to the Sphinx encounter through exploration.
- Start the Riddle of Rumination and identify the required completion condition in-game.
- Complete the riddle without leaving the encounter unfinished.
- Claim the reward and check inventory for three Ferrystones.
- Record the reward as collected; it is not a chest reset or repeat farm.
- Use the stones outdoors when you have active Portcrystal destinations selected from the map.
- Pursue this reward as part of Sphinx progression rather than making a separate trip solely for consumable travel items.
- The Eternal Ferrystone reduces routine demand for ordinary stones, so save these for situations where consumables are useful.

One-time riddle reward. The three Ferrystones are limited to that completion; no repeat cycle is established.
Common mistakes
- Assuming the reward comes from any Sphinx riddle; the specific Riddle of Rumination is the named source.
- Leaving before claiming or checking the reward; confirm the Ferrystones entered inventory.
- Planning to repeat the encounter for more copies; treat the reward as limited.
When to stop or switch
Stop once all three Ferrystones are in inventory. Continue Sphinx progression for its other rewards only if they suit your goals.
