After Each Boss
Killing a boss in Valheim changes the world itself, and this is exactly what starts appearing. 7 boss kills unlock 35 new spawn rules between them, from night raids in the Meadows to what begins roaming the biomes you have already cleared. Read from the spawn conditions rather than from patch notes.

Valheim World Change FAQ
Does the world get harder after killing a boss in Valheim?
Yes. 7 bosses each unlock new spawns, 35 rules in total. Killing the Elder, for example, starts Draugr appearing at night in biomes that previously had none.
Should I delay killing Valheim bosses?
It is a real trade-off. Each boss unlocks the gear tier you need next, but also makes the world more dangerous. This page lists exactly what each kill adds so the decision is informed.
Does killing a boss change the Valheim world?
Yes, permanently and globally. 7 bosses alter what spawns where, adding 35 new spawn rules between them — which is why creatures from a biome you have never visited start appearing near your first base.
Can you undo a world change in Valheim?
No. The flags a boss sets are stored on the world and there is no in-game way to clear them. Anything that starts spawning after a kill keeps spawning for that world.
Why are late-game creatures near my base?
Because a boss you killed unlocked them there. Those spawn rules are gated copies aimed at earlier biomes, so the creature is not native to the place you are finding it — it arrived with your progress.
