Quick answer

Repair the Inn, reach Renown level 55, and complete the Stone Refinery town-repair questline. At the finished refinery, 10 Stone makes 1 Refined Stone in 10 in-game minutes.

Before you start

The actionable checklist

  1. 01Finish the Inn repair first.
  2. 02Raise the town to Renown level 55.
  3. 03Complete the Stone Refinery repair questline.
  4. 04Bring 10 Stone for each Refined Stone you need.
01

Unlock the Stone Refinery

Refined Stone is tied to a town project, so it is not an early crafting-table recipe.

Repair the Inn before looking for the quest

The Stone Refinery town-repair questline becomes available only after the Inn has been repaired. Finish that project before treating a missing refinery quest as a bug.

Reach Renown level 55

The questline is also gated by Renown level 55. Keep completing requests, donations and town goals until the requirement is met, then follow the posted repair objectives.

02

Process Stone into Refined Stone

Once the refinery is repaired, the recipe is simple and fully predictable.

Use 10 Stone for 1 Refined Stone

Select Refined Stone at the Stone Refinery. The base recipe consumes 10 Stone and advances the clock by 10 in-game minutes.

Count the project before processing

Multiply the Refined Stone requirement by 10 to set your Stone target. Processing only the amount needed protects the Stone reserve used by other recipes, including Clay.

03

Improve Stone Refinery Efficiency

Ranching is not the only system with time-saving perks; refinery perks change the value of large batches.

Refined Rockery removes the base time

Refined Rockery reduces every Stone Refinery recipe by 10 in-game minutes. Because Refined Stone normally takes 10 minutes, the perk brings that recipe to zero processing time.

Break One, Get Two can add a bonus output

The Break One, Get Two perk may create a bonus item from Stone Refinery recipes. Do not budget a required project around a chance; count only the guaranteed output and treat bonuses as savings.

Field notes
  • Keep separate Stone stacks for confirmed construction needs and optional refinery conversions.
  • If you only need Clay, its Stone Refinery recipe uses 6 Stone rather than the 10 required for Refined Stone.
