The Yellow Wonderstone is a special item that can be placed into any windmill to create extra processed items when you process larger batches.
You can purchase the Yellow Wonderstone from Felipe’s Fineries at the bazaar for 140,000 G. It is available year-round after you unlock the stall (requires Bazaar Rank 5 and a bazaar request).

Effect Details
When active in a windmill, the Yellow Wonderstone grants bonus items based on how many items you process in a single batch:
| Batch Size | Bonus Items |
|---|---|
| 1–4 items | No bonus |
| 5–9 items | +1 item |
| 10 items | +2 items |
The bonus items are the same quality as the rest of the batch. This effectively gives you free extra products from the same ingredients.
Example: If you process Milk (x10) into Cheese (x10) with the Yellow Wonderstone active, you’ll receive 12 Cheese instead of 10.

Usage Tips
The Yellow Wonderstone is particularly valuable for:
- Maximizing profits: The bonus items are essentially free profits.
- Efficient resource use: Get more output from limited materials, especially useful for rare or seasonal items.
