About Coal
"Hmm a non-renewable energy source!"
Coal is a free-to-play Mining resource obtained at level 30 from coal rocks, granting 50 Mining experience per ore. It is the universal secondary ingredient for steel, mithril, adamantite, and runite bar smelting (2/4/6/8 coal per bar respectively), making it one of the highest-volume traded items in the game. Blast Furnace dwarves consume coal in massive quantities daily, keeping demand consistently high.

Market Strategy
- Highest-demand secondary ore in the game (every steel-and-up bar consumes coal)
- Blast Furnace halves the coal cost per bar, dramatically improving high-tier margins
- Coal bag (Prospector Percy reward) lets players carry 27 extra coal — essential for Blast Furnace
- Wilderness Resource Area and Mining Guild provide the densest sustained gathering rates
- Stable price floor — heavy production from miners is met by heavy consumption from smithers
