Valheim 1.0 Achievements & Devcommands Scope
How achievements operate across legacy saves, world modifiers, console commands, and dedicated servers.
1. Legacy Save Compatibility
Characters and worlds created during Early Access remain fully playable in 1.0. However, boss progression achievements trigger upon picking up or hanging the respective Forsaken Trophy on the sacrificial stones, rather than retroactively on login.
2. Devcommands & Achievement Locking
Using devcommands in local sessions or enabling console cheat modes sets an internal session flag that temporarily suppresses achievement unlocks for that play session. Restarting the client without console mode restored normal progression checks.
3. Multiplayer & Dedicated Servers
When defeating a boss on a dedicated server, all active players within the rendering proximity (roughly 64 meters) receive the victory flag and can claim the achievement upon trophy interaction.
