Refinery
In this building, you can pay minerals in exchange for sweet loot!
The Refinery is a building that is unlocked at Star base level 3, which allows you to turn minerals into presents similar to the mystery cubes.
It has three options for creating gifts, each of which required consumption of a certain amount of minerals. Before the 7-4-2023 update, this would be a percentage of your maximum mineral storage. However, this system was changed to be a fixed amount. The flawed present takes 8 hours to produce, the imperfect present 18 hours, and the perfect present takes 48 hours. Only one present can be created at once. The rewards inside each cube can be found on the Mystery Cubes page.

Trivia
- The characters on the sides of the Refinery presents are written in the Starling alphabet. It just translates to A 1 for level 1 Refinery's flawed present, up to C 4 for level 4 Refinery's perfect present.
