Coal is a basic resource. It can be obtained in many different ways, primarily from rocks or Dust Sprites in The Mines, purchased from Clint at the Blacksmith shop, or using a Charcoal Kiln. It may also be produced by recycling trash or found in Fishing Treasure Chests. A random amount of coal may be found in addition to metal ores by Panning.
