To find Bonemass in Valheim, you must explore the challenging Swamps biome, specifically searching within Sunken Crypts and certain ruined structures for a special runestone called a Vegvisir, which will mark his Forsaken Altar on your map.
Locating Bonemass in Valheim
Bonemass is one of Valheim's formidable bosses, and finding his summoning location is a key step in progression. His altar is always situated within the treacherous Swamps biome, but its exact spot is randomly generated in each world, requiring players to actively search for clues.
The Swamps Biome: Your Starting Point
The journey to Bonemass begins by thoroughly exploring the Swamps biome. This dark and dangerous area is characterized by its perpetually dim light, waterlogged terrain, and unique flora and fauna. Bonemass's Forsaken Altar, where he can be summoned, is hidden somewhere within these murky depths.
Unearthing the Vegvisir
The primary method for pinpointing Bonemass's exact location is by finding a Vegvisir. A Vegvisir is an ancient runestone that, when interacted with, reveals the nearest boss altar on your in-game map. For Bonemass, these crucial runestones are typically found in specific areas within the Swamps:
- Sunken Crypts: These dungeon-like structures are often found embedded in the ground within the Swamps. They are rich in scrap iron and other resources, but also contain various hazards. Vegvisirs are frequently located inside these crypts.
- Ruined Structures: Occasionally, you might encounter dilapidated stone or wooden structures scattered throughout the Swamps. A Vegvisir might sometimes be hidden within these ruins.
Reading the Map and Preparing for Battle
Once you interact with a Bonemass Vegvisir, a distinct skull icon will appear on your map, indicating the precise location of his Forsaken Altar. Traveling to this marked spot will bring you to his summoning platform, which is notably adorned with withered bones.

Essential Tips for the Search
- Be Prepared: The Swamps biome is dangerous. Bring good armor, powerful weapons, and always have Mead: Poison Resistance on hand to counter the prevalent poison effects from leeches and blobs.
- Mark Locations: As you explore, use your map to mark areas you've already cleared or discovered, especially crypts, to avoid revisiting them unnecessarily.
- Ship Exploration: Often, the easiest way to find new Swamps biomes is by sailing your ship along coastlines until you spot them.
Finding Bonemass requires methodical exploration and preparation, but with the help of a Vegvisir, you'll be ready to challenge the putrid mass of the Swamps.
