Every player needs a way to breathe underwater in Oblivion Remastered. The Fin Gleam Helm gives you water breathing, night vision, and the power to sense life nearby. Knowing the Oblivion Remastered Fin Gleam Helm location will help you get this powerful gear fast.
Start by finishing the prison escape at the beginning of the game. Open your map and look for Anvil, a city on the far west side of Cyrodiil.
You can travel there quickly using fast travel. When you arrive, walk to the docks near the water. You will see the sea and some small islands far away.

Where You Find The Island
From the docks in Anvil, walk west along the shore. You will see a small island close to the coast. This island has no name on the map, but it is easy to spot. Climb to the highest rock on the island. Stand on the northwest side of this rock and look out over the water.

Save your game again before you jump into the water. Face west or a little to the southwest, then jump in and swim straight out. Dive down to the bottom of the sea. The water is deep, so keep swimming until you see the ground.
Look for two big rocks close together on the ocean floor. Between these rocks, you will see a skeleton. Next to the skeleton lies the Fin Gleam Helm. Pick it up and put it on.

The helmet will give you water breathing, night vision, and the ability to sense life around you.
This concludes the guide on the Oblivion Remastered Fin Gleam Helm Location, so get ready to explore all the hidden spots under the sea.
