Concentrated coal rocks

Concentrated coal rocks are located in the Living Rock Caverns.

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 Varrock armour 2 or 3, they will even have the chance for their armour to mine an additional ore, resulting in up to 3 ores.

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.

These rocks require 77 mining to mine. These rocks do not have gems!

Some players may use this to mine lots of coal rather quickly as there is a bank deposit nearby.
