Port Growth
How upgrades, production, storage, population, and Docks progression affect a port.
Port growth is shaped by buildings, resources, storage, population, ships, and map pressure. Each upgrade changes what the port can store, build, defend, unlock, or produce.
Core buildings
Section titled “Core buildings”HQ supports broad progression and faster growth. Docks shape fleet access and shipbuilding pace. Warehouse sets resource capacity. Farmland affects available population for construction and ships. Trade Post, Port Defenses, Forest, Workshop, and Mines add logistics, defense, and production functions.
The buildings interact. A high Docks level can still be limited by population. Production above Warehouse capacity cannot be stored. A port with valuable stored resources can attract raids, especially when Port Defenses and stationed ships are low.
Resource production
Section titled “Resource production”Forest, Workshop, and Mines provide steady wood, cloth, and metal. Their value depends on current resource needs, upgrade costs, ship costs, storage capacity, trade access, and raid income.
Wood-heavy needs often come from broad building growth. Cloth and metal become important for ships, defenses, and higher upgrades. Repeated shortages can come from production levels, spending patterns, trade limits, market activity, or losses from attacks.
Storage and population
Section titled “Storage and population”Warehouse and Farmland affect capacity rather than direct map power. Warehouse decides how many resources the port can hold. Farmland affects whether construction and ship orders have enough population available.
Warehouse capacity matters when production, trade arrivals, market activity, voyage rewards, or raid loot add resources. Farmland matters when construction chains or ship queues require population. Population pressure becomes visible when an order cannot start.
Upgrade pacing
Section titled “Upgrade pacing”Long upgrade chains depend on several constraints at once: HQ requirements, resource costs, storage capacity, population, build time, Docks progression, and the port’s defensive situation.
Useful facts to compare before an expensive upgrade:
- Whether the upgrade unlocks a ship, building, trade option, or defensive tool.
- Whether the port has enough resources, storage, and population after the order starts.
- Whether another support building is the current source of a visible bottleneck.
Specializing ports
Section titled “Specializing ports”Ports can develop around different roles. A staging port often involves Docks, ships, and nearby defense. A resource port involves production and Warehouse capacity. A trade port involves Trade Post progress, Trade Ships, and enough storage to handle resource movement. A border port is exposed to different attack pressure than a safer interior port.
Specialization changes dependencies. Armadas and Trade Routes can move resources between ports, while local storage and local defense still affect how much a specialized port can hold and how exposed it is.
