Shaft Miner - Digs the ores on the shaft and banks them to the crate near the elevator.

Although the miners might seem to just perform automated functions in the game, it is helpful to know that you can improve them individually. This is done by earning costumes that they can wear -- which in return will improve their stats. Costumes in the game can earned for free by drawing on Treasure Chests as reward on the expedition, or as a form of reward upon performing certain tasks in Events.There are multiple outfits drawn each time you open a chest, and the selection is always random. Rarer types of chests would draw out rarer types of outfit and a bigger collection of them to boot.

The main difference of each outfit can easily be spotted by checking the multiplier values seen on the upper left part of the costume. The higher the value, the higher multiplier you get with your miner’s performance. Each outfit can also be upgraded/leveled up as well by simply collecting a required number of copies of a pertaining costume, seen on the bottom part of it. If for instance your costume has the value (e.g. x / 9) at the bottom, you’ll need to earn 9 copies of that costume to upgrade it. Upgrading a costume will result to an increased value in its performance multiplier.
