Valheim seed map guide: where your world's bosses and traders are

The seed map draws your whole Valheim world from its seed and marks every boss altar, trader camp and dungeon before you set foot there. In the game your map shows only the ground you have crossed, and a boss altar appears on it only after you read that boss's Vegvisir. A world holds up to three Eikthyr altars within 1,000 metres of the centre and up to five Bonemass altars between 2,000 and 10,000 metres out.

Find your seed

The start screen lists every world with its seed under the world name. Type that seed on the seed map and open it. The world is built in your browser the way the game builds it, terrain first and locations last. The first view shows the whole world, with the spawn point in the Meadows at its centre.

If you already play the world, use Load world and pick the folder that holds its world files. The map then shows what your save holds, including the places your visits have already fixed. The save file guide shows where that folder is on Windows, macOS and Linux.

Follow the boss order

Each boss waits at one of several altars of its kind. The Vegvisir you read in the game points to the closest one from that stone, which is often not the closest one to your base. Search a boss's name on the seed map and the results list every altar of that kind, nearest first from the spawn point. Use Choose on map and click your base to measure from there instead.

• Eikthyr: up to 3 altars in the Meadows, within 1,000 metres of the centre.
• The Elder: up to 4 altars in the Black Forest, 1,000 to 7,000 metres out.
• Bonemass: up to 5 altars in the Swamp, 2,000 to 10,000 metres out.
• Moder: up to 3 altars in the Mountain, within 8,000 metres.
• Yagluth: up to 4 altars in the Plains.
• The Queen: up to 5 entrances in the Mistlands.
• Fader: up to 3 altars in the Ashlands.
• Kall Fimbulbringer: up to 3 boss rooms in the Deep North.

Plan the next base around the altar you can reach first. A Swamp with a Bonemass altar close to the Black Forest edge saves a long sail once The Elder is down.

Traders, ore and dungeons

Haldor, Hildir and the Bog Witch each have up to ten possible camps. The first camp a player reaches becomes the trader's home and the game removes the others, so the map shows candidates rather than one fixed shop. The trader guide covers how to read them.

Ore follows the boss order too. Copper deposits sit in the Black Forest, and Sunken Crypts in the Swamp hold Scrap Iron. Search a location kind such as Troll Cave or Sunken Crypts to list every one on your world, nearest first. Each pin links to that location's page with its creatures and loot.
