About Farm

Priority: Medium-High

The Farm produces grain, one of the three core resources needed for troop training, building upgrades, and research. Running out of grain is one of the most common bottlenecks for mid-game players, so upgrading your Farm early pays dividends across every other activity.

Upgrade Tips

1Upgrade the Farm as soon as you have surplus wood and herbs — it will pay back the cost quickly in passive grain income.
2Higher-level Farms dramatically reduce how often you need to gather grain on the world map.
3Combine Farm upgrades with Granary upgrades to avoid resource cap overflow.
