Concentrated coal rocks

Concentrated coal rocks are located in the Living Rock Caverns. They require a Mining level of 77 to mine ore from them and give 50 experience per ore mined. There are 8 concentrated coal rocks in the game, which is double the number of concentrated gold rocks in the game. These rocks do not have gems! It's maybe advised to go from 65 - 77 with granite and mine coal to 80.

Concentrated coal can be pretty good experience, although granite or concentrated gold are better alternatives. With 77 mining and a rune pick you can get about 27k experience per hour. With 99 mining, dragon pickaxe, lava titan, and a coal bag, it's possible to get 45k experience an hour.

While mining, players can get either 1 or 2 coal ores at a time; when 2 ores are mined, players get the message: "You manage to mine two pieces of coal!" If a player is wearing any level of Varrock armour, they will even have the chance for their armour to mine an additional ore, resulting in up to 3 ores.

It is recomended to mine in one of the unofficial worlds due to the high combat levels of the Living Rock Protectors and Living Rock Strikers.



Trivia

 * Unlike all other rocks (except those in Living Rock Caverns) these do not run out of ore; rather, they are collapsed by the stomping and fist pounding of the Living rock creatures.
 * Some players may use this to mine lots of coal rather quickly as there is a bank deposit nearby.
 * Currently, Worlds 84, 77 and 88 are the unofficial worlds to do this in. There are a lot of players, so the chance of getting hit by a creature is greatly minimized. Be aware though that these worlds, World 84 especially can become very Laggy when large numbers of players attempt to access the servers. As always players are recommended to log on to a world that has a geographically close server and low Ping value.
