Concentrated coal deposit

Concentrated coal deposits are clumps of coal located in the Living Rock Caverns beneath the Dwarven Mines. They require level 70 Mining to mine and have a durability of 500, a hardness of 140, and an experience multiplier of 0.8. There are eight of these deposits in the caverns. Concentrated coal deposits contain a much larger supply of coal than a normal coal
