Additionally, those who have purchased the Master Vacation Bundle for Like a Dragon: Infinite Wealth receive access to the exclusive endgame dungeon The Big Swell.

To effectively prepare for their late-game and endgame adventures, players should certainly consider crafting the highest quality weapons for their favorite jobs. Each job in Like a Dragon: Infinite Wealth has its own ultimate, 7-star quality weapon that players can craft at Julie’s Gearworks with the right materials and a moderate sum of cash. Each of these weapons requires a specific base weapon that the players must first obtain, and locating these weapons isn’t always a straightforward task. Infinite Wealth’s Aquanaut is a wacky surfing and sea-themed job available for its male characters. Players looking to craft its ultimate weapon, Ocean King’s Board, will first need to get their hands on a specific five-star weapon before they can proceed. Here’s where players can find the Aquanaut’s Board in Like a Dragon: Infinite Wealth.

Where to Find the Aquanaut’s Board

The Aquanaut's Board is a five-star quality surfboard that is essential for crafting the Aquanaut's ultimate weapon, the Ocean's King Board, alongside other materials. To obtain the Aquanaut’s Board, players will need to seek out and defeat a specific pack of Keepers of the City within Hawaii. These enemies are more difficult than regular enemies encountered on the apparently mean streets of Hawaii and can be easily identified by a gold crown icon over the head of their leader.

Keepers of the City which drop the Aquanaut's Board in Like a Dragon: Infinite Wealth.

The Aquanaut’s Board is obtained by defeating a group of Keepers of the City located on the eastern end of Aloha Beach. To quickly reach these enemies, players should fast-travel to the E Aloha St. taxi stand and proceed along the beach until directly south of Makani Ave. The group is found near an outdoor shower below a patch of grass on the map. The level of these enemies will depend on the player's current progress in Infinite Wealth's main story.

If the Aquanaut's Board does not drop after defeating the Keepers, it may be due to their level being too low. In such cases, players must leave the area and then return, causing the enemies to respawn at a higher level. This more challenging group of Keepers, typically level 30 or above, will always drop the Aquanaut's Board as a guaranteed item upon their defeat.
