The cave goblin miner is an NPC found outside of Dorgesh-Kaan in the Dorgeshuun Mines. They can be found strutting about the rocks or mining ore. They wield a bone pickaxe that is not obtainable by players, but instead is just used to symbolize the Dorgeshuun's ability to adapt to new use of materials. If you are found attacking one, a cave goblin guard will yell, "Stop that!", and will target you.
