A free mod for Valheim, by Sixefyle.

Repair All is an easy-to-use tool that can be used to repair all items, including weapons, armor, tools, and more. To use it, you just need to press the repair button once.

You can configure it in the settings if you want to check if the item can be repaired in the crafting station you’re using! It is also possible to set a default configuration, in which case the tool will be used every time you launch the game.

Extract the BepinEx zip file where the game is installed, then place RepairAll.dll in the plugin folder to complete the process.
