The progression at a glance

Stone tools→Copper + tin→Bronze pickaxe→Iron→Steel pickaxe→Star Iron

Copper and tin are alloyed into bronze. Forge a bronze head and assemble the pickaxe to unlock iron mining. Do not travel for iron with only a stone pickaxe.

Open M and plan a route between regions. Resource availability varies across the world. These are biome clues, not fixed coordinates or a guarantee that a deposit is still stocked.

Two routes to iron

Iron Ore and Bog Iron use the same basic ratio: 2 raw material + 1 Charcoal → 1 Iron Ingot. Both need a bronze pickaxe or better to gather. Choose the route that fits the region you can reach.

At the next stage, one Steel Ingot takes 3 Iron Ingots + 2 Charcoal. If you are starting from Iron Ore, that means six ore and three charcoal just for the iron, then two more charcoal for the steel step.

Obsidian, Blacksteel and Star Iron

In Ashlands, look for large black glass deposits for Obsidian. Blacksteel combines Steel Ingots, Obsidian and an Ember Core, with Emberstone as fuel in a Blast Smelter.

Star Iron is gathered from meteorite craters with a Steel Pickaxe. Use a Blast Smelter to turn it into Star Iron Ingots. It no longer serves as an ingredient for ordinary steel.

Make the return trip count

Take food, set a rest point and leave nonessential valuables behind. Carry weight can prevent sprinting. Upgrade your bag or make shorter trips; dropped Pack goods have a recovery timer and are not private.
