Getting More Coal
It is a total bottleneck and it is for a really long time. You basically have three options outside of just mining more coal.
- You can grind up on Silver and Gold bars (really just gold) because it doesnt need coal until you get the Cape which halves coal requirements.
- You can Mine till you get THAT cape and you get one coal whenever you mine anything.
- You can work on Alt Magic till you get super good at that and can smelt with no coal.
None of those are great, they require a LOT of grinding and levels, but the are options.
Personally, I would just mine coal overnight every few days till you dont need as much anymore (thats what I did).
