Withered Bones are Valheim items you’ll find in the Swamp Biome of the video game developed by Iron Gate, and even though they may seem important, they serve a single purpose.
The Valheim Withered Bones; however are also quest-items, and once you use them to complete your objective, you should not carry them anymore.
So, let’s quickly go over the Withered Bones in Valheim, and learn how to use them and where to find them.
What Is A Valheim Withered Bone
As said, the Withered Bones are quest-items, meaning that you’ll need them to summon the third boss in the game, named Bonemass.
Other than that they are pretty much useless; that’s why once you defeat Bonemass, you can stop carrying them.
According to the game’s description, a Withered Bone is “A giant bone, knotted like old wood”. A single bone has a weight of 1.0, and you can stack up to 30 in a slot.
Finally, they can be teleported, and you can see them below.
Where To Find Withered Bones In Valheim
These items are very easy to find provided you know where to look for them and you have the required equipment.
They are located in the Swamp Biome and they have two possible locations:
- You can find them by mining the Muddy Scrap Piles
- Or you can find them in small alcoves in the Sunken Crypts
Let’s start with the Muddy Scrap Piles.
These deposits can be found outside the Sunken Crypts as well but they require the Wishbone which is dropped by Bonemass.
Since you need the Withered Bones to summon him, you’ll want to look for the Scrap Piles inside the Sunken Crypts.
Once inside, use the Antler Pickaxe to mine the Muddy Scrap Piles and get these bones, as well as to move from one room to another.
You’ll be able to craft the said pickaxe after you deal with Eikthyr.
Keep in mind though that the Valheim Withered Bones can also be found without mining. Just look around for alcoves whenever you enter a new room.
The moment you get 10 you can stop searching for them because that’s the number of bones you need to summon Bonemass.
How To Use The Valheim Withered Bones
Assuming you have 10 Withered Bones, next you’ll want to find the location of Bonemass.
This means that you’ll continue to explore the Sunken Crypts until you find the Vegvisir Bonemass which is a runestone like the one below.
Examine it, then mark the location of the third boss on your map.
Next, exit the crypt and travel to the summoning altar. Here you should be able to see a rather large skull (pictured above).
Equip the 10 Withered Bones in one of your quick slots, then make the offering by standing in front of the skull’s mouth.
This will summon Bonemass, and this is why you need the Valheim Withered Bones.
Once you deal with him there is no point to collect these items anymore unless you want to fight the third boss again.
That’s how you use the Withered Bones in Valheim and where you find them, so start mining, and also don’t forget to look for Bloodbags.
