About Lumberyard

Priority: Medium-High

The Lumberyard is your source of wood, which is consumed in massive quantities when upgrading high-level buildings and training advanced troops. A well-upgraded Lumberyard keeps your construction queues running without constant world map gathering.

Upgrade Tips

1Wood is consumed heavily at Sanctuary levels 20+, so keep your Lumberyard close to your current Sanctuary level.
2Upgrading the Lumberyard early reduces dependence on gathering, freeing your marches for combat.
3Pair with Lumber Depot upgrades to store the extra wood output without hitting your resource cap.
