The Unmanned Mining Tool, or UMT, is an automated drill that mines for you while you occupy yourself with other tasks such Battle Dungeons, Chip Wars, or just about anything else.
To start your unmanned mining session, you will need the right tools, which are far from cheap when compared to the ordinary mining tools and their respective batteries. Go to the Ore Refiner merchant and click on “Item trade” (a). Then purchase one of the three available UMT types (b). The only difference between the three UMT tools is the durability, outlined below. Because other races can attack and destroy your UMT, the durability acts as your UMT’s hit points. Lastly, you will want to purchase some batteries (c). The UMT has two battery slots, so it is best to buy two batteries.
