Mine Craft is a short world quest available in Genshin Impact in the Mondstadt region.
Your only objective is to speak to Wagner to learn more on mining.
Here’s a walkthrough of Mine Craft in Genshin Impact.
Speak to Wagner
Wagner is the blacksmith inside Monstadt near the front gate. Talk to him and he’ll tell you more about finding ores.
You will then unlock rich ore reserve icons on your map. If you go to that area on the map, you’ll find some ore deposits that may be useful for you.
