Valheim bosses: where every altar spawns and how to summon each
All 8 Valheim bosses: where each altar can spawn, which vegvisirs point to it, the summon, what it resists and what its drop unlocks.
Valheim has eight bosses, and each one waits at a fixed spot that world generation places when the world is made. Finding the altar is often harder than the fight. This guide covers where each altar can spawn, what points you to it, the summon, and what the drop opens up. For the gear to bring to each fight, see the progression guide.

Finding altars faster
- Read every vegvisir you pass. Each one adds the nearest altar for its boss to your map.
- Pick a seed with close altars. In seed bAHdRbYfkG, five altars are reachable on foot from the spawn, the nearest at 880 m. The best seeds guide has more.
- Check the map before you sail. The seed map shows every boss location for a seed, so you can plan a route instead of searching the coast.
