Coal can be mined from concentrated coal rocks in the Living Rock Caverns. Concentrated coal rocks have a chance of yielding two coal at once, unlike normal coal rocks, and can give multiple coal before collapsing. Players should mine from the 3 concentrated coal deposits in the south-eastern part of the Living Rock Caverns. When the player’s inventory is full then they can bank their coal using the bank deposit, located in the centre of the cavern.
