Banks Salt traces recovered from battlefield casualties. Level sets hourly processing throughput before excess spoils.
Process Salt recovered from enemy Swarm casualties. Hourly throughput limits the harvest and excess spoils, so a large battle does not guarantee unlimited banked Salt.
To establish this building, you need 🏛️ Main Building level 5; the Race restriction shown in the statistics below.
For later upgrades, the Main Building must also reach the target level. The level table shows the resource and time investment before bonuses.
The building definition has no direct structural or active power upkeep. Check the powered extractors, crafting and recruitment that support its use when planning the wider grid.
📸 Screenshot wanted: the Collector Spire detail panel in a colony (level, upgrade cost and its main controls visible). If the building has a Race name, one shot per Race is ideal.
