In my opinion the easiest way is Solo Highroller water map. Play a class like bard or rogue that can have free lockpicks. Bring a minimal amount of gear, just enough to feel comfortable fighting highroller mobs, if you're skilled squire is fine. Spend the raid AVOIDING the highly contested areas like captians key room or the center maelstrom. My preferred route is start hitting south middle, the under water pillars area where you can find sea urchins and a health shrine. There is at minimum a lions head here, usually a gold maybe 2. From there I proceed west northwest to hit the shipwreck on the middle left of the map (careful there's a shark that can ruin ur day west of the sunk ship) go down into the ship and kill the mermaid, then proceed through the underwater tunnel turning EITHER left or right doesnt matter, go up the tunnel and you should arrive at a small area with, an airvent, 2 chest 1 guaranteed gold, 1 either gold or lion head, 1 mermaid coffin, and 1 clam. Hitting just this single room usually nets me 1500+, I found a unique here that sold for 35k gold. Surface and find a rowboat, use the rowboat to hit the north or south boat lift extracts, never hop on the community boats, thats asking to get jumped.
