All the recorded coal sources
- CoalCoalA basic fuel used by furnaces and several production loops. nodes and coal bags in the mining area: the structured record lists both at a 100% yield.
- Rock piles: a listed 9.61% coalCoalA basic fuel used by furnaces and several production loops. drop — the same rock piles that advance the Skull Hat pity counter.
- Hunting acid chameleon bugs: a listed 8% coalCoalA basic fuel used by furnaces and several production loops. drop.
- The blacksmith shop sells coalCoalA basic fuel used by furnaces and several production loops. at 50 G each; coal sells back for only 10 G, so buying is for emergencies.
- One faction material-exchange trade also rewards coalCoalA basic fuel used by furnaces and several production loops. for doomsday crops.
Mine it in the river valley

Head to the mining area in the lower-right part of the river valley map.

Look for the black stones — an independent player report confirms these always yield coalCoalA basic fuel used by furnaces and several production loops..
- 03
Clear the nearby rock piles too; they occasionally drop extra coalCoalA basic fuel used by furnaces and several production loops..

Every coalCoalA basic fuel used by furnaces and several production loops. node you clear also advances the Amber pity counter — 30 nodes guarantees one Amber.
Burn wood in the Charcoal Kiln
The Charcoal Kiln recipe sits in the Industry branch of the tech tree, and the quest line gives you one kiln for free, so you never farm coalCoalA basic fuel used by furnaces and several production loops. nodes forever. Each batch takes one hour. The structured record also lists higher-yield kiln batches from the rock-wood and bamboo-tube materials (3 and 2 coal per batch of four); those two item names follow the Chinese wiki, so their in-game English spellings may differ.
Burn it, don't gift it
- Smelting consumes coalCoalA basic fuel used by furnaces and several production loops. constantly: copper, iron, gold, and steel bars, plus glassGlassA processed material produced through furnace recipes. and rubber, each take 1–2 coal per batch.
- Generators burn coalCoalA basic fuel used by furnaces and several production loops. as fuel, so an automated base drains the stockpile faster than furnaces alone.
- Every villager listed in the gift table dislikes coalCoalA basic fuel used by furnaces and several production loops. (−7.5% friendship), so keep it out of your gift rotation.
- The hunting guild board can post a coalCoalA basic fuel used by furnaces and several production loops.-digging task, so a spare stack occasionally pays off directly.
