Today we're going to explore a few ideas for new carts. We'll begin with something that would make the lives of every miner a lot better: the Mine Cart.
A Mine Cart would be a large objects you can pull, much like the cart we have now. The main difference would be that instead of accepting liftable objects, it would have a special inventory (similar to a stockpile) that would only accept mining byproducts. It could be limited to stone and ore, but frankly I believe it would be best if it accepted other things like petrified seashells, strange crystals, and gems as well.
A Mine Cart would require the Wheel Wrighting and the Metal Working skills for sure, but it might also require Basic Mechanics or even Deep Artifice.
To buil a Mine Cart you would require some wood components, as well as metal (hard metal, most likely). [Note: one or two Strange Crystals could also be added to the recipe as a decoration, just to make those crystals useful for something].
The Mine Cart should be more efficient at moving ore than the current system of carts, wheelbarrows, and boats. A normal cart filled with wheelbarrows can bring up to 450 ore. That's 525 if you also lift a wheelbarrow, or 600 if you lift a boat with two wheelbarrows in it. That being considered, the Mine Cart should carry at least 750 ore/stone, or more.
It's time to give miners some well deserved love.
