ValheimGuideTurning a Valheim world setting off only applies to new worlds. The console commands that clear baked-in modifiers, and the 1.0 achievements warning.
Valheim writes your world's modifiers into the world file the first time the server starts that world. After that, turning a setting on works any time: change it in the dashboard, restart, done. Turning a setting off does not take effect on an existing world; you clear it from inside the game with the admin console. This is a Valheim engine behavior on every host, not a Haptic restriction. And from Valheim 1.0 on, the console route has an achievements cost worth knowing about first.
When the server boots, Valheim reads the settings you chose and writes them into the world file as global keys (for example nomap, passivemobs, nobuildcost). Once a key is in the world file, Valheim treats it as part of the world's permanent state. Later starts can add new keys, but they never remove keys that are already written.
Read this first if you play with achievements (Valheim 1.0). The console commands below require devcommands, and from the 1.0 release on September 9, 2026, Iron Gate has said using most developer commands permanently flags your character and the world as modified, which locks achievements for them. If achievements matter to your group, consider a fresh world with the right settings instead: your old world stays in your backups, and characters carry over. See keep your world or start fresh.
You need to be a server admin first: add yourself in your server's Admins section and restart. See Admins, allowlist, and bans.
Join your server and press F5.
Type devcommands and press Enter. The console replies with Devcommands: True.
Use the reference list below for the setting you want to clear.
Type save to write the world to disk immediately. Then turn the same setting off in your Haptic dashboard too, so the server does not re-apply the key on its next start.
Sliders reset with setworldmodifier:
Combat Difficulty: setworldmodifier combat normal
Death Penalty: setworldmodifier deathpenalty normal
Resource Drops: setworldmodifier resources normal
Raid Frequency: setworldmodifier raids normal
Portal Restrictions: setworldmodifier portals normal
Toggles clear with removekey:
No Map: removekey nomap
Passive Mobs: removekey passivemobs
Player Events: removekey playerevents
No Build Cost: removekey nobuildcost
Fire Hazards: removekey fire
No Boss Portals: removekey nobossportals
No Craft Cost: removekey nocraftcost
No Workbench Required: removekey noworkbench
All Pieces Unlocked: removekey allpiecesunlocked
All Recipes Unlocked: removekey allrecipesunlocked
The Hammer preset is five build and craft toggles at once, so clear each of its keys individually: nobuildcost, nocraftcost, noworkbench, allpiecesunlocked, allrecipesunlocked.
If a setworldmodifier command does not seem to take, use setworldpreset default instead: it resets all five sliders to Normal at once, and you can then re-apply the ones you still want from the dashboard.
Not sure what is set? listkeys prints every global key on the current world.
Just turn it on in your Haptic dashboard and restart. New keys apply on the next start, no console needed, and no achievements impact.
If a command does not work or your world reverts after a restart, message us in Discord or open a ticket, and we will sort it out with you.
