SurtlingFuel

Tired of burning through wood to make coal? Put those surplus Surtling Cores to work! This mod lets you use Surtling Cores as a premium fuel source in both the Smelter and Blast Furnace.

Features

Surtling Cores as fuel — walk up to a smelter or blast furnace and add cores directly
4x fuel value — 1 Surtling Core provides 4 coal-equivalent fuel (smelts 2 ores)
2x smelting speed — ores process twice as fast while burning core fuel
Cores take priority — if you have cores in your inventory, they'll be used first over coal
Fully configurable — tweak all values via BepInEx config file

Configuration

After first run, edit BepInEx/config/com.dejan.surtlingfuel.cfg:

BlastFurnaceFuelPerCore	4	Coal-equivalent fuel per core in the blast furnace (2 coal per ore, so 4 = 2 ores)
SpeedMultiplier	2.0	Smelting speed multiplier while burning cores
