"Shaped like a cobra poised to attack, the Darkmatter mine is a scary machine that shows just how far we've come."
The Darkmatter Mine is a Legendary-tier mine. It's the cheapest dropper in the shop that has an ore value in the millions. By the time you can afford this dropper, you would already have a more powerful dropper (most likely from rebirth or from unboxing vintages or exotics). However, some people use it in Overlord setups due to virtually no risk of clogging.
