Bireme

Overview

The middle upgrade in the Chronicles ramming-ship line, between Monoreme and Trireme.

Availability and investment

Bireme becomes available in Chronicles. It is associated with Chronicles (Chronicles naval & specialist roster). The listed cost is not separately recorded and the training time is not separately recorded. This tells you when it can first join an army and which resources must be reserved alongside Villager production, upgrades, and other military lines.

• Upgrade path: Monoreme → Bireme → Trireme

Combat profile

The available combat values are included here so the numbers can be read as a profile rather than an isolated list. Hit points and armor describe how long the unit can remain exposed; attack and any bonus damage describe what it threatens; range, reload, accuracy, and movement describe how reliably it can engage or disengage. A value shown for a whole upgrade line applies to the listed stages as recorded, so compare the stage names instead of treating the line as one base unit.

• Melee attack: 10
• Hit points: 120
• Melee armor: 3
• Pierce armor: 4
• Ship armor class: 9
• Line of sight: 5
• Attack bonus vs. Rams: 3
• Attack bonus vs. Buildings: 3

Field use

Use the unit where water control matters: protect fishing and transport routes, contest enemy ships, or support a landing. Its impact depends on the map’s shore access and the rest of the fleet.
