Runecarved

Author: Izzemi

Built on the Jotunn mod stub by the Valheim Modding Community.

Runecarved adds rarity tiers and per-item modifiers to existing Valheim equipment, creating a more varied and unpredictable gear progression.

AI use disclosure

This mod was partially created with the assistance of generative AI (GitHub Copilot coding agents). All changes were reviewed and tested by the author. All assets, sprites, models, and artwork were created without any AI assistance.

Installation

Either:

Install from thunderstore. Requirements: BepInExPack Valheim and Jötunn (both are installed automatically if you use a mod manager).

• Install r2modman or the Thunderstore Mod Manager.
• Select Valheim, create a profile, and search for this mod.
• Click Install with dependencies, then Start modded.

Download one of the releases from the repo page.

• Install BepInEx for Valheim by extracting BepInExPack Valheim into your Valheim folder (usually C:\Program Files (x86)\Steam\steamapps\common\Valheim). Run the game once, then close it.
• Install Jötunn by placing Jotunn.dll in Valheim\BepInEx\plugins.
• Put the .dll file in Valheim\BepInEx\plugins. A subfolder such as plugins\ModName\ also works.
• Launch Valheim through Steam.

Building

Requirements: Windows, a Valheim install with BepInEx and Jötunn installed (for example through a mod manager profile), and the .NET SDK (or Visual Studio).

1. Clone the repository.

2. Create Environment.props in the repository root (it is git-ignored) with the paths for your machine:

   <Project>
     <PropertyGroup>
       <VALHEIM_INSTALL>C:\Program Files (x86)\Steam\steamapps\common\Valheim</VALHEIM_INSTALL>
       <BEPINEX_PATH>C:\path\to\BepInEx</BEPINEX_PATH>
       <MOD_DEPLOYPATH>C:\path\to\BepInEx\plugins</MOD_DEPLOYPATH>
     </PropertyGroup>
   </Project>
   

3. Build Runecarved.sln (for example dotnet build Runecarved.sln, or Build in Visual Studio). The build copies the plugin DLL into MOD_DEPLOYPATH.

4. Start Valheim.
