Valheim Swamp Key: Where to Use It & How to Get It

Valheim’s Swamp Key is one of the key items you’ll find on your adventure across the world teeming with Norse mythology and Viking culture. Whether you’ve come across the door that requires it and you’re wondering how you get it, or you’ve already obtained it but don’t know where to use it, we’re here to help. Here’s everything you need to know regarding the Swamp Key in Valheim.

How to Get the Swamp Key

The Swamp Key is dropped from The Elder in the Black Forest. The Elder is the second boss in Valheim, and is a giant tree. It can be summoned by obtaining three Ancient Seeds and burning them at the sacrificial altar in the Black Forest.

Upon defeating the Elder, you’ll be rewarded with the Elder Trophy and the Swamp Key itself.

Where to Use the Swamp Key in Valheim

The Swamp Key is used to unlock the Sunken Crypts inside the Swamp. It can be used multiple times, too, meaning you can revisit this location, though it’s worth noting that both the loot and monsters don’t respawn, so their probably isn’t that much point coming back.

Inside the Sunken Crypts, you’ll find all kinds of resources such as Amber, Coins, Rubies, and Ancient Bark, among other things.

After you’ve visited the Sunken Crypts, you will no longer have a use for the Swamp Key, so you can throw it away if you really want to.
