When you enter the instance area, Anise's magic disguises you as a bandit so that you can enter their hideout without any trouble. Since you're new in the crew, you have to gain their trust before they'll let you in on any secrets. Crusher Dan first asks you to clear some skale out of the cave. This could be one of your first times dealing with underwater combat, so it can be a little tricky. Be sure to use your left click to look around while underwater, as you can aggro things above and below you as well, and it's easy to grab more enemies than you are ready for. Also, if you haven't done any water combat yet, your weapon skills won't be unlocked and you might have a starter underwater weapon still. If that's the case, just get the skale above the surface and fight them on land. It can be a lot easier.

After clearing the skale out, Crusher Dan isn't quite finished with you, so he asks you to take out Ol' Scabfin, a large veteran skale. He gives you the bait and you set it outside to fight him. He has a good amount of health, and hits pretty hard. Be sure to use your dodge when you can, and keep on him, as he regens health. Also, don't keep the bait as a weapon. It's not very good.

Once you take him out, Crusher Dan suggests you check in with others to ask how you can help. First go talk to Doc Howler, who asks you to get some plants for the plan. Get them for her and she lets you know that Pete's crew is going to poison the water in the Salma district.

Finally, talk to Riot Alice, who will end up fighting you. Afterwards she thinks she recognizes you, and says that Pete's not the man he once was, that he's dangerous now and only cares about gold. You suggest she gets out of the gang and she says she's considered it. Now to head back to Logan with your newfound information. He tells you that Quinn has been taken to one of Two Blade Pete's hideouts in Claypool. You can either help Logan take care of the poison, or save Quinn again.
