Mining

 * Place a Wood Minion on your Private Island with an Auto Smelter to generate Coal.

Shop
You can buy Coal at the Mine Merchant near the hub spawn for  per piece or from the Iron Forger located near the Gold Mine.

However, after the recent Bazaar update you can buy a maximum of 640 Coal a day, limiting its effectiveness.

Collection
Collecting pieces of Coal increases the player's Coal Collection, which grants useful items and perks upon collecting certain amounts of pieces of Coal.

Usage
Coal can be used as a crafting ingredient, as Minion Fuel for Minions, and as a brewing ingredient. Coal increases Minion produce speed by for 30 minutes. Coal can also be used to brew Haste Potions.

Coal can be sold to any Merchant for apiece.

Trivia

 * The item description is frequently changed, rendering some Coal not stackable. This can be fixed by dropping old Coal on the floor to update all the items to the latest description.
