Part 3: Mining
You will need to mine to get materials. Slowly and slowly you will need to upgrade.
You will need a pickaxe to mine. In Terraria there are all types of ores. for example Diamond, Copper, Iron and more. The more advanced you get the more ores you will be able to mine.
You can also use a drill to mine ores. Most drills are better than pickaxes. Drills have more pickaxe power than pickaxes
