These vaults contain rare gear that can be helpful on your journey, and the region of "Marunweem Lake" iconMarunweem Lake has a high number of treasure vaults for you to explore. The guide below goes over how to overcome these treasure vaults’ tricky puzzles and where each of them is located on the map.

If you follow the road past the Coastal Mine Floo Flame, you will come to a treasure vault at the base of a mountain passage. There is no door, so run straight inside until you come to the room with the multiple pull levers.

Central Mountain Treasure Vault at Marunweem Lake

This treasure vault is a bit trickier to get to. You will want to pull up your map and mark it so that you can track it easily, as you will need to land your broom and go through the mountain passage on foot. Beside the treasure vault are several goblins. Defeat them and head inside. You will find a Depulso device and hit it until the rocks move across to the other side of the room.
