Valheim portal settings: block or allow portals

Open the World page, find the Difficulty card and change Portals. You can choose Everything can go through, Not during a boss fight or No portals. Save, then restart the server. The change applies at the next start. More about the game: Valheim servers.

What each choice does

As the preset sets it keeps the game’s normal rule, or the rule your Preset gives.

• Everything can go through. The wiki says everything can be portalled at all times, except tamed animals.
• Not during a boss fight. Portals do not work while a boss is active, says the wiki.
• No portals. No portal works anywhere in the world. Players must walk or sail.

What a portal normally cannot carry

On the normal rule, a player can use a portal, but some items cannot go through. The wiki lists:

• all ores, and the metals made from them: copper, tin, bronze, iron, silver, black metal, flametal and their scrap,
• the dragon egg, Hildir’s three chests, the mechanical spring, the charred cogwheel, the Dvergr extractor and the iron pit.

A portal stone lets these through, says the wiki. Everything can go through lets them through without one.

Change it

1. Open the World page.
2. In Difficulty, open Portals (1) and choose a value (2 to 4).
3. Choose Save. The panel says: “Saved. The game reads these when it starts, so restart the server to use them.”
4. Choose Restart at the top of the server page.

If you pick a Preset as well, your Portals choice is applied after the preset and wins for portals.

Go back to normal portals

A world remembers the modifiers it was started with. Choosing As the preset sets it later does not remove a setting the world already holds. The Difficulty card shows what the world remembers: “The world remembers: …”.

To return to the normal rule, set Portals to As the preset sets it, tick Clear the world’s own modifiers first, then Save and restart.

By hand

The panel writes one of these on the start line. Put it after any -preset. The values are in the game’s own manual.

• -modifier portals casual for Everything can go through.
• -modifier portals hard for Not during a boss fight.
• -modifier portals veryhard for No portals.

That pairing is the panel’s own.

If it does not work

• Portals still work. Restart the server. A saved change is read at the next start.
• No Save button. Your role may not allow editing the startup settings.
• A choice will not go away. Tick Clear the world’s own modifiers first, save and restart.
• Players are stuck far from base. Choose Everything can go through or set Portals to As the preset sets it (after clearing the world’s modifiers).

The Map page still shows portals players built, in its Portals layer. It draws them from the world’s last save and does not read this setting. See world modifiers for the others.
