Today, we are going to talk about the Water Temple. Once Morga installs a treasure crane on your boat, you can now raise things from the bottom of the ocean. Try using this crane anywhere you see a shiny spot.

According to Morga, the Water Temple is sunk in southern dark sea. Follow Morga's advice and search for the temple.

When you pull the Water Temple out from the water, it's time to explore. There are water-type monsters inside the shrine, so make sure to prepare the right Denpa Men party and equipment. You will come across a door that won't open at the time, but remember where this door is. When the time is right, it will open for you.

Be prepared for a tough trial waiting for you in the deepest part of the Water Temple.
