To access the Seiraimaru shipwreck in Genshin Impact, players must find The Intact Key. They will need to solve a puzzle to get the Key.

The Intact Key is required to open a door within Seiraimaru in Genshin Impact. Genshin Impact recently introduced its new Inazuma region for players to explore. It features new level-up items, missions, and underground passageways with puzzles to solve. Seiraimaru is a location near the islands of the Asase Shrine and Amakumo Peak in the region. It's an abandoned shipwreck that includes puzzles to solve.

In order to grab everything this area has to offer, players will need to get the Intact Key. Finding the key itself isn't too difficult if players know where to look, but it's fairly easy to miss on the first visit. Players will need the Intact Key in order to complete the puzzle hidden within Seiraimaru. Inside, after players complete the puzzle, they will be rewarded with Luxurious Chests. These contain Primogems, Mora, Electro Sigils, Berserker's Indigo Feathers, and much more.

The nearest Waypoint to get to Seiraimaru will be located near Koseki Village. Players can warp to this location and travel to the western end of the island to find and enter the shipwreck.

Get the Intact Key in Genshin Impact

Inside the ship, the floor features glowing yellow panels. To light them, players will need to step on the shapes with the same corresponding symbol. There will be a group of Geo enemies that spawn, but players can take these out quickly. Ignoring the floor panels, players should search for a large crack in the floorboards. There will be a chest floating on the water between the broken planks. Inside the chest, players will find the Intact Key.

Now, players can head over to the locked door in the room and use the Intact Key to open it. There will be a puzzle featuring four wheels that players can interact with. To complete this puzzle, players should make sure each wheel's pointy end face towards the center. This will create a square and will unlock the Luxurious Chest.

Inazuma itself features 21 Luxurious Chests, each requiring players to solve puzzles to access them. Players should seek these out since the rewards inside them make it easier to Wish for 5-star characters. Primogems are amongst the most valuable resource in Genshin Impact, and collecting more of them becomes harder the higher level the player is, so Luxurious Chests will be especially important for these players.
