The Flagship is the centerpiece of every fleet in Sea of Conquest. It functions simultaneously as an aggro tank that absorbs enemy fire, as a cabin host providing all production and support facilities, and as the fleet anchor whose level caps the maximum level and strength of all companion ships. Upgrading the Flagship is therefore the most important ongoing task in the game: every level gained unlocks new cabin slots, potentially adds fleet slots, and raises the ceiling for the entire fleet.
The Flagship is the only vessel in the fleet where cabins can be constructed and upgraded. These cabins produce raw materials, cook food for gold, or enhance combat capability. Because the Flagship level defines the maximum level of every other ship in the fleet, each Flagship upgrade is simultaneously an investment in overall fleet strength.
In every naval engagement, the Flagship fulfills the role of the aggro tank. It draws all enemy attention, allowing companion ships to deal maximum damage without taking fire. For this reason, the Flagship should be built as defensively as possible — emphasizing HP and Armor — while the side ships are specialized for offense.
| Role | Description | Build Focus |
|---|---|---|
| Aggro Tank | Draws enemy attacks away from fleet | High HP and Armor (AMR) |
| Cabin Host | Houses all production and utility cabins | Prioritize cabin upgrades |
| Fleet Anchor | Caps the maximum level of all fleet ships | Regular level upgrades |
The Flagship level unlocks new cabin slots, fleet slots, and gameplay systems. The table below summarizes the most important milestones:
| Level | Fleet Slots (Side Ships) | Key Unlock |
|---|---|---|
| 1–4 | 2 | Basic cabins; gang join unlocked at Level 4 (costs 400 Emeralds) |
| 5 | 2 | Gathering nodes on the map become accessible |
| 8 | 2 | Beginner's protection ends — players can now attack you |
| 13 | 2 | Gold becomes the primary limiting factor for upgrades |
| 21 | 2 | Requires Astrologer's Chamber Level 20 |
| 22 | 3 | Third side ship slot unlocked |
| 31 | 4 | Fourth side ship slot unlocked |
| Endgame | up to 5 | Maximum fleet: 1 Flagship + 5 side ships (6 total) |
The Flagship houses four specialized food-production cabins. These supply ingredients for the Galley and Mess Hall and contribute indirectly to gold generation:
| Cabin | Primary Product | Bonus Products | Usage |
|---|---|---|---|
| Chicken Coop | Eggs | Agave, Maize, Potatoes | Cooking in the Galley |
| Cattle Shed | Milk | (Raw meat possible) | Cooking in the Galley |
| Salvage Bay | Fish (aquatic products) | Various seafood | Cooking in the Galley |
| Water Cabin | Fresh Water | Berries, Honey, Grapes | Cooking and brewing |
Production cabins must be emptied regularly. Assigning sailors to each cabin as workers maximizes output rate.
Galley (Kombüse): The Galley processes raw ingredients gathered from the four production cabins into cooked dishes and beverages. Recipes range in tier from common to legendary; higher-tier dishes sell for significantly more gold in the Mess Hall.
Mess Hall (Messe): The Mess Hall is the onboard sales facility. Cooked food is sold here for gold, subject to daily transaction limits that increase with each upgrade. Regular Mess Hall upgrades are worthwhile for consistent gold income.
In addition to cabins, the Flagship has four technical upgrade categories that raise its base combat stats:
| Upgrade Area | Primary Effect | Priority |
|---|---|---|
| Hull (Rumpf) | Increases HP and Armor | Highest priority |
| Weapons (Waffen) | Increases Attack and damage output | High |
| Engine (Antrieb) | Increases sailing speed | Medium |
| Crew (Besatzung) | Increases crew capacity and efficiency | Medium |
A core principle for the Flagship build: HP is the most important stat when selecting ship parts. Since the Flagship absorbs all enemy fire, it must be as durable as possible. Ship parts consist of four types — Cannon, Sail, Figurehead, and Navigation Helm. Each part carries random attributes that can be improved through enhancement, with additional bonus stats unlocked at enhancement levels 5, 10, and 15. Set bonuses (equipping 2 or 4 matching pieces) provide further combat advantages.
| Level Range | Recommended Focus |
|---|---|
| 1–7 (Beginner phase) | Build Shipbuilder's Study (double it if possible), Astrologer's Chamber, Cargo Hold upgrades |
| 8–12 (Exposure phase) | Gun Bay cabins for combat power, Oarsmen Quarters for sailing speed |
| 13–20 (Gold bottleneck) | Optimize trading routes, upgrade Mess Hall, activate auto-trading |
| 21–30 (Advanced) | Bring Astrologer's Chamber to Level 20, unlock 3rd fleet slot at Level 22 |
| 31+ (Endgame) | Unlock 4th and 5th fleet slots, bring all fleet ships up to Flagship level |
