JotunnLib

Jötunn (/ˈjɔːtʊn/, "giant") Lib is a modding library for Valheim, with the goal of making the lives of mod developers easier.
Get the mod on NexusMods or Thunderstore!

❗❗ Deprecation notice ❗❗

JotunnLib is no longer under active development, and has not been for quite some time. If you are looking to create a mod, please use Jötunn, the Valheim Library instead! If you are installing JotunnLib as a dependency for any mods, go ahead, but please bug the mod author to make the switch to JVL instead :)

The only updates that will be made to JotunnLib going forward will be to fix any compatibility issues or game-breaking issues - no new features will be added.

Jötunn, the Valheim Library is the direct successor to JotunnLib. It was originally created by the teams behind ValheimLib and JotunnLib as a means to unify the Valheim modding community, and it has evolved into a massive project with many contributors from the community.

Thank you again to all the developers and players who tried out and used the original JotunnLib ❤️

    Note: If you already have used any other mods, you likely already have this installed.
