|pirate coin necklace|
Gerbard the Snitch in the Sunken City (-42, 0) has a problem. He has gambled away all of the booty. He will reward you with a necklace if you can scrounge up five pirate coins.
The Pirate Coins drop on Cursed Cutthroats in the zone. These come in groups of 3-4 typically, so you may need a group.
Return to Gerbard the Snitch for your reward.
