Tips & Strategies

Great for farming Black Pearls for end game items such as the Tek Replicator, but they are very hard to find underwater so finding them can be a challenge. If you’re looking for these creatures I’d recommend scuba gear and high level water dinos just in case you run into a situation with a aggressive water dinos (Mosas, Plesis, Megladons, Squids, and etc.) One more tip, don’t let the Eurypterid attack, because of their poisonous attacks that can knock you out using a crossbow to kill them from a range is highly suggested.
More Eurypterid Utility Tips
If you need black pearls on valguero, there is a cave hidden in the jungle on a hill near green ob that you can enter and drop down a big hole into a water pool. There are 4 or 5 pools in the cave, each with up to 15 eurypterids in them, you just have to kill the eels before you get the eurypterids. And the beauty of this cave is that if you leave it (make sure to bring grapples to get out if you don’t want to go the long way) the eurypterids will be back and you can farm another few hundred black pearls. It’s even easier in single player where you can exit to main menu to refresh the spawns.
