Version: 1.0.0
Author: Marsarah
Marsarah Tweaks is a modular and optimized port of my previous project, MarsarahMod.
It features numerous code improvements, cleaned-up logic, and ServerSync integration โ all wrapped into a cleaner, more maintainable package.
Each feature is grouped and configurable, allowing players or server admins to tweak Valheimโs grind and balance just the way they want.
Reuploading this mod, whether in part or in full, is not permitted.
This mod requires BepInEx for Valheim, available here:
https://valheim.thunderstore.io/package/denikson/BepInExPack_Valheim/
.zip file.MarsarahTweaks.dll into your Valheim/BepInEx/plugins folder.โ ๏ธ Note: This mod must be installed on both the server and all clients.
This mod is modular and customizable.
Valheim/BepInEx/config/Marsarah.MarsarahTweaks.cfgโ All gameplay-affecting features are synced using ServerSync.
โ UI-related features are local and not synced.
๐ Players will be disconnected if their mod version differs from the server.
Prevents non-admin players from modifying any configuration values while in-game.
