The Seiraimaru is a wrecked ship in Genshin Impact that is host to several puzzles, one of which gives you a rust worn key. This large ship is near Koseki Village, on Seirai Island. It is definitely worth exploring, since it is full of treasure. However, it isn’t as easy as simply strolling into it, because these puzzles make walking around its interior quite challenging. Our Rust Worn Key Location – Seiraimaru Puzzle Genshin Impact guide will show you how to get this key in the easiest possible way. Since some things are easier to show than they are to put into words, we also have our very own video which also shows how to do this Seiai Maru Puzzle Genshin linked at the bottom of the article.
Genshin Impact Rust Worn Key Location
Head on over to the wreckage of the Seiraimaru. Once you are here, you will see four turning mechanisms surrounding an Exquisite Chest. To open it, rotate 90 degrees clockwise 1x the lower-left one, then rotate 90 degrees clockwise 1x the upper-left one. Next, rotate 90 degrees counterclockwise 1x the upper-right one and rotate 90 degrees counterclockwise 1x the lower-right one. The chest will now open, and with it – the way to the lower decks. Summon an Electrogranum and proceed to the lower decks. In here, there is a floor puzzle where you have to step on the plates in the exact order. Our video below shows the precise combination you have to do here.
As soon as you have done this correctly, another Exquisite Chest will open in that room, and a new way forward will become available. Loot this chest, turn around and walk up the stairs. You will see a Common Chest here and a point which you can investigate. Loot these and you will get the Rust-Worn Key.
