This guide will show you how to locate and use the mysterious Sea Salt-Crusted Key. You do need to complete Mona’s event portion, “Temple of the Star Latitudes,” before you do this.

If you’re stuck on Mona’s version of Minacious Isle, you can interact with a blue platform on the east side of the island to swap it back to the original island. To toggle the islands, the platform blue you used to access her domain may not be the one you are looking for. We’ve marked the location of one of the toggle-able platforms below:

How to locate the Sea Salt-Crusted Key

The Waverider can be used to sail from the western island to Minacious Isle once it has returned to its original state. You can jump into the hole. You should find a lock puzzle in the area you have just entered. But ignore it and jump into the hole. Break the rock it was digging in order to find a brilliant spot.

Use the Sea Salt-Crusted Key

When Minacious Isle is set in Mona’s form (with no islands to the west), head to the southern part of the island to access entrance to ruins.

Note that there is an entrance to ruins at the bottom of the island, where you beat up a digging Hilichurl for Mona’s story domain, but this is the wrong entrance. The entrance we’re talking about is above the one with the digging Hilichurl.

Follow the pathway once you are inside and flip the switches quickly. The one on your left is the closest to the entrance. The other can be found on top of a heap of rubble. After you have flipped them, go up the ladder to reach the opening at the ceiling.

Clear the Hilichurls after climbing up. The Sea Salt-Crusted Key can be used at the gate.

Strangely enough, there’s another Sea Salt-Crusted Key in the pot directly in front of the gate. We haven’t found a use for this key yet, but once we do, we’ll update this guide.

The puzzles in this room are for the “Thus Was the Work Done in Vain” world quest line.
