The Blue Wonderstone is a special item that can be placed into any windmill to dramatically speed up the processing times of your processed goods.

You will get the Blue Wonderstone as a reward for completing a request for Isaac. The other five wonderstones can be purchased from Felipe’s Fineries, making the Blue Wonderstone the only one you cannot purchase.

Effect Details

When installed in a windmill, the Blue Wonderstone cuts all processing times in half for all items made at that windmill.

This effect works independently of wind power bonuses, meaning that wind power effects & the Blue Wonderstone’s effect can both apply simultaneously to help you craft items even faster.

Example: An item that normally takes 8 hours to process will be completed in 4 hours with the Blue Wonderstone active. If wind conditions also provide a speed bonus, the total time will be reduced even further.

Usage Tips

The Blue Wonderstone is particularly valuable for:

  • Tool upgrades: Higher-tier tools like Orichalcum equipment require long processing times that benefit greatly from the 50% reduction.
  • High-volume fast production: When you need to process many batches of items quickly, the time savings can compound significantly.
  • Late-game crafting: Yellow Windmill recipes often have base times of 10+ hours, making the Blue Wonderstone useful for more efficient production.
