How do I produce more resources in Dragonfire?

Production runs through the resource buildings in your Stronghold, upgraded via the Infrastructure research tree:

• Granary → Food/Grain
• Lumber Mill → Wood
• Quarry → Stone
• Foundry → Iron

Each research node at max level (I) gives +6,000/h of production on its resource (Granary I, Lumber Mill I, Quarry I, Foundry I = +6,000/h each).

Two levers to go faster:

1. Level your Infrastructure research
2. Harvest the resource tiles on the map (see the "how to farm" articles)

A reminder: building production resets every Reign, so you re-grind your output each new season.
