WHERE & HOW TO FARM

Where to farm

Swamp Caves and Deep Swamp; Deep Desert Caves for Ancient Fossil Ore.

Swamp and Desert cave systems serve different ore targets. Swamp Caves contain Ivy Ore, Deep Swamp is the location for Mycelium Ore, and Deep Desert Caves contain Ancient Fossil Ore. Pick one destination based on the recipe you intend to make instead of expecting all three materials in one region. Deeper cave travel needs appropriate combat supplies and a Pickaxe. After mining, return to the settlement to smelt the ore and decide which progression craft to pursue next.

GET STARTED

How to farm

Before you go

Access to the target biome and cave depth.
A Pickaxe for the relevant ore-bearing rocks.
Combat equipment, food and inventory space.

Check your crafting goal and write down whether you need Ivy, Mycelium or Ancient Fossil Ore.
Travel to the matching region: Swamp Caves for Ivy, Deep Swamp for Mycelium, or Deep Desert Caves for Ancient Fossil.
Explore the cave corridors while clearing threats near the route.
Mine exposed veins of the target ore with your Pickaxe.
Inspect nearby branches for more target rocks and collect useful Stone as space allows.
Return to the settlement before supplies or health are depleted.
Smelt the ore into bars and use them for the selected equipment or crafting recipe.

Farming tips

Keep the target region matched to the ore; a Swamp trip does not substitute for Deep Swamp when seeking Mycelium.
Process one ore goal at a time to avoid hauling unrelated materials.

Repeat, collect and use

Repeat the relevant cave route for additional ore; individual cave yields are variable.

Common mistakes

Searching the wrong depth: go to Deep Swamp for Mycelium rather than stopping in Swamp Caves.
Expecting Ancient Fossil in Swamp: seek it in Deep Desert Caves.
Continuing with low supplies: return and restock before pushing deeper.
