Where is the Forbidden Treasury in Diver Dave? As you progress through the main storyline of Diver Dave, you will encounter a mission to go to the Merfolk's Forbidden Treasury. However, the location of the treasury is not very clear and needs to be found through specific methods. But don't worry, the process described below will allow you to find the location of the treasury with 100% certainty, and you can immediately head inside for your adventure once found.

To go to the Forbidden Treasury and get the key to the Glacier Passage, you first need to advance the main story to Chapter 4, which will unlock the missions related to the treasury and allow you to explore it. Once the mission is triggered, there's no need to rush to find the location of the treasury; instead, follow the main story's guidance back to the Merfolk Village to look for Tianjin and have a conversation with him to learn about the Forbidden Treasury.

After talking with Tianjin, he will have Suwan guide the players to the Forbidden Treasury. This trip to the treasury will be shown in an animated form, requiring no player input throughout the entire process. After the animation ends, the player will appear at the entrance of the treasury with Suwan. Engage in the main dialogue with Suwan again, and interact with him to open the door to the Forbidden Treasury, allowing the player to venture into the treasury alone for their adventure.

In addition, it's best to complete all the tasks inside the treasury after entering, as John Watson will destroy the entrance with missiles after you leave, preventing any further exploration of the treasury. After dealing with John Watson, return to Tianjin and give him the key from the treasury to complete the mission.

The above is the answer to where the Forbidden Treasury is in Diver Dave. The method described above is the fastest way to find the treasury, and it does not require players to perform overly complex operations. All you need to do is prepare for exploring the treasury. You can try this method in the game.
