Ok this is a tricky quest. So please read caefully. There are a total of 10 slaves in the mines of nurga. Any 1 of these slaves can be 'free' at one time. When one of the slaves is freed another will take it's place. If Rock Shaper Dritam has already been freed you can do the hand in to him and not have to do the Free slaves part.

'Free the slaves'

In the Mines of Nurga, there are slaves of various races who wish to be set free. Each slave asks for 3 items:
a small iron shackle key
a pouch of supplies
and a strong restorative

The small iron shackle key drops from Overseer Pruckib, the pouch of supplies drops from Taskmaster Yajo, and the strong restorative drops from Slave Driver Nimol.

Once you've handed in the items, 6 waves of 5 goblins spawn. At the end, a named will spawn (Mine Overseer Narrik). When he is killed, the slave escapes and flees to his home where he gives another quest.

A different slave will spawn to take the freed slave's place.

First thing you want to do is see if Rock Shaper Dritam is already freed. Head to -1677, 2103 in the Frontier Mountains. If he's up you will not have to do the free slave part you can do the hand in below and get the gloves. Rock Shaper Dritam does not de spawn after a hand in the only time he de spawns is when somone does the 'free the slaves' part and releases another slave. If he is not up you will have to do the above part to free him.

'The hand in'

After Rock Shaper Dritam has been freed from slavery in The Mines of Nurga, he will respawn at -1677, 2103 in the Frontier Mountains. He wants you to bring him the following

3 Flame Dancer Beads (drops off goblin flame dancers lvl 47)
1 Blood Thirsty Rat Hide (drops off A Blood Thirsty Mine Rat lvl 48)

You receive Earthen Gloves of Wisdom
