Port

What it does #

Builds additional trading ships one at a time after Port level 1. A starting city already owns one free trading ship, even before the Port is built. Ship prices depend on total ship number, not Port level.

Port level reduces ship construction time by 2% per level above 1. The marketplace unlocks at level 3. Each trading ship carries 5,000 resources; canceling its construction refunds 75% of the paid cost, rounded down.

The level table uses base values before VIP, active monument, and other conditional bonuses. A requirement is checked against the target level.

Every level #

Corrected: The marketplace opens at Port level 3, not 10 (see above).
