📋 About This Mod
Factorio-style modules for Valheim!
Overclock your Kilns, Smelters and Blast Furnaces with Surtling Cores.
The Overclock Cores are created in the forge.
Add them to the Kiln, Smelter or Blast Furnace with [1-8] buttons (do not target the Coal or Ore inputs, but the main structure)
The hover text doesn't show up until there is at least 1 overclocking core in the Smelter.
Productivity stores partial products in an internal buffer, and are released when it reaches 100%.
The modules come with a trade-off, so balance them well!
Most values are configurable:
Speed core bonus (default: 20%)
Speed core efficiency penalty (default: 50%)
Efficiency core bonus (default: 25%)
Efficiency core speed penalty (default: 10%)
Productivity core bonus (default: 10%)
Productivity core speed penalty (default: 25%)
Productivity core efficiency penalty (default: 25%)
Default maximum of Overclock cores on each Kiln, Smelter and Blast Furnace (default: 4)
Maximum of additional Overclock cores on each Smelter (default: 4)

✨ Key Features
📊 Pros & Cons
✅ Pros
- Taps into the Factorio-style automation fantasy—if you love min-maxing production, this is right up your alley
- Simple concept: slap some cores on your furnaces and watch them work faster
- Decent traction for a niche mod: 58 endorsements and 1,866 downloads show there's a dedicated audience
⚠️ Cons
- Last updated in September 2023—might be out of sync with the latest Valheim patches
- Only covers Kilns, Smelters, and Blast Furnaces; no word on other production buildings
For Valheim players who enjoy optimizing production chains and want a bit of Factorio-style efficiency in their Viking survival. Skip if you prefer vanilla progression or want broader building changes—this is strictly a furnace tweak.
💡 Beginner Tips
- Make sure you have Surtling Cores stockpiled—they're the fuel for this mod, so hit those swamp dungeons
- If you're using a mod manager like BepInEx, drop the mod into the plugins folder to keep things tidy
- Test overclocking on a single smelter first to see if the speed boost is worth the core cost
