HardHeim

Odin's world, just brutal.

HardHeim is a Valheim difficulty mod built with BepInEx and Jötunn. It makes progression more demanding through heavier copper ore, a custom death penalty for skills, and dark crypts that require a handheld light source.

Features

• Copper Ore Weight: Configure the weight of copper ore on the server.
• Surtling Core Weight: Configure the weight of Surtling Cores on the server (defaults to 150 kg).
• Crypt Surtling Core Scarcity: Burial Chambers contain at most 1 Surtling Core (configurable spawn chance, defaults to 30%).
• Custom Death Penalty: Skills below level 50 use percentage-based loss; skills from level 50 use fixed reductions, with a smaller reduction at level 60 and above.
• Dark Crypts and Caves: Ambient lighting, environmental light, fog, and dungeon light sources are disabled indoors, making handheld lighting necessary for exploration.
• Enhanced Handheld Lights: Player torches and Dvergr lanterns have adjusted light intensity and range while inside dark interiors.
• Lighting Note: Camera zoom can affect the perceived brightness and range of handheld lights because Valheim adjusts light detail based on distance.
• Server Synchronization: Configuration is synchronized to clients, and every player must have the mod installed.

Installation

The easiest way to install HardHeim is using a mod manager like r2modman or the Thunderstore Mod Manager.
