In Valheim, players will come across a variety of biomes, each one more dangerous than the last. But each Valheim biome has its own secrets and hidden locations. A big hidden item in the swamp biome is the Swamp Key.

In the swamp biome, players will come across all manner of creatures and materials that they can use to create bigger and better tools and lodgings. Players will be able to find Valheim iron and bog iron in this biome as well as Sunken Crypts that are locked and cannot be breeched. Unless players have obtained a Swamp Key, anyway.

The Swamp key will open any locked Crypt door in the Swamp biome, giving players access to treasure and mud piles that can be mined for iron, leather, and withered bones. They also contain some difficult battles; in the Crypts, players will find Blobs, Draugr, and Draugr Elites.

Ironically enough, the Swamp Key is not found in the Swamp Biome. Instead, players will have to venture to the Black Forest biome, where copper ore is found in Valheim. Once there, players will need to battle Graydwarves Brutes and Graydwarves Shamans and collect three Ancient Seeds from them when they drop. Next, players will have to find the location of the Black Forest altar; since the locations in Valheim are procedurally generated, the exact coordinates of a player's altars will vary depending on their seed.

Next, lay the three Ancient Seeds on the Black Forest altar, and this will summon one of the secret bosses in Valheim: the Elder. The Elder is an Ent-like tree person that brings a lot of friends to the battle. The Elder and its minions are a difficult enemy to defeat, and will not fall easily even to those who have the best gear and weapons available to them. However, this co-op game does allow players to bring along some help; they will want to bring some of their own friends along as well to ensure that they are not overrun by the group of evil treefolk.

Once the Elder and his buddies are defeated, the Swamp Key will drop as loot from the battle. This will allow Valheim's Viking-themed co-op warriors to celebrate their victory by collecting the spoils from the Crypts in the Swamps. The dungeons inside the Crypts are not easy, but players who can defeat the Elder should be able to hold their own against the elite enemies.

Valheim is available now in Early Access on PC.
