As an Iron, stone spirits kind of just sit in my bank, and I'd imagine in mainscape these spirits have next to no use at all. My idea is a machine that uses stone spirits as fuel, and brings you back the ores based on X amount of spirits.
Example, the machine will take in 10 coal stone spirits and spit out 1 coal.
The machine will use fewer spirits the more valuable the ore is, because that's when the spirits become more valuable, such as using 2 Dark Animica Spirits to produce 1 ore.
the cost of running the machine can be Soul Runes and Body Runes.
