World seed

The in-game dialog for creating a new world. The seed input field can be seen below the name input field.

A world seed is a map seed used to initialize Valheim's pseudorandom number generator that determines how a world is generated. All worlds generated from the same seed will have the same layout for any given game version.

When creating a new world in the main menu, the game opens a dialog where the player can enter the world name and seed. The input field for entering the seed is initially filled with a random seed that can be replaced with a custom seed.

Generating Online Maps

You can also generate worlds online using the website listed below created by wd40bomber7. You can easily view all boss locations, tombs and other important land marks. One thing to note though, only the first trader you visit will spawn. The others will not actually be created. Also, this generator is in very early development. Some maps may be slightly incorrect or different from in-game maps and can become incorrect after new updates to the game have been published.
