Foothills mining ingredient
Windrose Sulfur: How to Get & Use
Windrose sulfur is half of the gunpowder recipe and one of the few resources you can only collect from a single biome. Every batch of Gunpowder consumes 25 units of windrose sulfur, so once you commit to crafted production this becomes a constant background errand. This page lays out where to mine it, what tool you need, the secondary purchase route, and the most efficient circuit for a single afternoon’s farming run. The only meaningful change to sulfur supply across the game’s run history was the Hands boss reward, which we cover under the alternate sources note below.
How to Get Sulfur in Windrose
Windrose sulfur drops only from yellow rocky outcroppings scattered across the Foothills. The outcroppings are visually distinct — bright yellow against the muted green of the biome — so once you have seen one you will spot the others quickly. Each node yields between two and four units per swing and depletes in three to five swings before respawning on a fixed timer of roughly twenty in-game minutes.
You cannot harvest these outcroppings with anything weaker than an Iron Pickaxe. A wooden or stone pickaxe simply bounces off, and the game shows no contextual hint, which is why new players sometimes assume the resource is bugged. Craft an Iron Pickaxe at the Workbench using Iron Ore from the Coastal Jungle before your first Foothills run and you will avoid an embarrassing return trip.
There is one alternate source. After defeating the Hands boss, the Natural Resources Merchant adds yellow ore to its rotating stock. The merchant’s prices are not cheap, but the route is invaluable when you need to top up between expeditions and do not want to commit a full mining circuit. Treat the merchant as an emergency valve, not a primary supply line — the math always favors the Foothills run for raw volume.
Windrose Sulfur Uses
The dominant use for windrose sulfur is the Gunpowder recipe at the Millstone. Twenty-five units feed every craft of one Gunpowder, paired one-to-one with twenty-five Ash. Because Gunpowder powers every ranged firearm in the game, this single recipe drives essentially all sulfur demand across a typical save.
A small amount also feeds late-game alchemy and demolition charges, but those routes are optional and most players never touch them. If you only ever use the Millstone, the planning numbers stay simple: one craft, two ingredients, and twenty-five of the yellow stuff per round.
The Production Planner above the page can convert any target stockpile into the exact sulfur, ash, charcoal, and wood you need. Pair it with a single Foothills mining circuit and you will have a precise picture of how many trips a real production run actually requires before you set out.

Best Sulfur Farming Locations
The Foothills hold roughly fifteen outcroppings spread across three loose clusters. The northeast cluster, near the cave entrance most players use to enter the biome, is the closest to camp and worth running first. The central cluster sits along the river bend and tends to have the most nodes per square meter, which is where serious mining circuits anchor.
The far western cluster is harder to reach but yields denser nodes — five or six together — and is where weekend stockpile runs pay back the travel time. Mark these clusters on your map the first time so the second loop is half as long as the first.
Windrose Sulfur Tips & Strategy
Three habits make windrose sulfur farming feel cheap instead of grindy. First, never enter the Foothills without an Iron Pickaxe — the resource cannot be harvested without one, and a return trip costs more than the missing tool ever could. Second, batch your circuits: hauling 100 units back per trip is twice as efficient as two 50-unit trips. Third, sweep wild Corn on the same circuit; Corn shares the biome and lands free in your inventory while you are already moving.
