Starsteel is a valuable resource that can be obtained in the location The Edge of the World. To start collecting it, you need to unlock the Starlight Mine building.

Inside the Starlight Mine, you can gather several types of resources:

• Construction gneiss

• Blacksmith quartz

• Starsteel

Each of these resources has a different chance to get. Some are guaranteed with every attempt, while others belong to the “chance to get” category, meaning they won’t appear every time.

If you want to increase your chances of receiving rare resources like Starsteel, you should upgrade the Starlight Mine.

With each upgrade, the chance to obtain these valuable items grows, making it easier to stock up on Starsteel over time. On the screenshots, you can see how the chance to get each resource increases with building upgrades.
