If you’ve ever played a Dark Elf campaign in Total War: Warhammer 2 and left your Black Ark sitting idle in a coastal bay, you’re far from alone. Most new players write these floating fortresses off as overpriced naval curiosities, but they’re one of the most powerful unique faction tools in the entire game. Learning how to use Black Arks in Warhammer 2 can turn a slog of a Dark Elf playthrough into a hyper-aggressive, conquest-heavy run where you never run out of resources or reinforcement options. I’ve put over 120 hours into Dark Elf campaigns across every difficulty level, and I still get shocked by how much utility these ships pack if you use them right.
Core Basics: How to Use Black Arks in Warhammer 2 for New Players
You’ll unlock your first Black Ark automatically within the first 10 turns of any standard Dark Elf campaign, and you can build additional ones in level 4 or higher port settlements once you expand your territory. Each Black Ark functions as a mix of mobile port, army support hub, and independent naval combat unit, all in one package. You don’t have to assign a lord to a Black Ark to use its core functions, though adding a dedicated admiral will unlock far more perks as it levels up.
Black Arks have two primary operating modes that you can swap between at any time for no cost. When anchored, it projects a 3-province range buff that applies to all your owned coastal settlements in the area, including reduced recruitment time for Dark Elf units and a small boost to local slave income. When mobile, you can sail it across any ocean tile, engage enemy fleets in battle, and launch raids on coastal enemy settlements without needing a dedicated ground army. It even has its own permanent garrison that replenishes automatically over time, no recruitment cost required.
Don’t make the common new player mistake of sailing your first Black Ark straight into a cluster of high-level pirate fleets right after you unlock it. Its base garrison is strong enough to take on small, unupgraded raider groups, but it will get wiped out instantly by Dwarf ironclads or High Elf dragon fleets if you encounter them too early. Stick to safe home waters for the first 20 turns while you build up its strength.
Maximizing Raid and Conquest Potential With Your Black Ark
The biggest perk of Black Arks for early and mid-game play is their ability to generate massive amounts of resources without forcing you to commit to full wars. Black Arks can launch land raids on coastal settlements without putting your ground armies at risk. You’ll send the Ark’s garrison to fight the settlement’s local defenders, and if they win, you get all the gold and slaves from the raid. If they lose, you just wait 10 turns for the garrison to replenish for free, no penalty other than lost time.
When you do start conquering coastal territory, park your Black Ark adjacent to any settlement you’re sieging for an immediate 15% siege strength buff, plus you can recruit units directly from the Ark to your besieging army in a single turn. That cuts out the need to march reinforcements across half the map from your home territory, which is a game-changer when you’re invading far-off continents like Lustria or the Old World. Every battle or raid your Black Ark participates in also gives a 20% bonus to slave gains, which is the backbone of any strong Dark Elf economy.
If you’re not sure where to start with your first Black Ark, these are the most high-impact early uses:
- Raid coastal Bretonnian and Empire settlements for the first 20 turns to stock up on slaves and gold without declaring full wars
- Park adjacent to your first few conquered coastal provinces to reduce recruitment time for Dark Elf infantry and cavalry by 1 turn
- Use it to clear out minor pirate fleets in your home waters to secure trade routes, as its base garrison is stronger than most early pirate groups
Raiding with your Black Ark doesn’t count as a formal declaration of war if you don’t get caught, so you can farm resources from much stronger factions early on without triggering a full-scale invasion of your territory. Just make sure to sail away quickly if you spot an enemy fleet patrolling the area.
Upgrading Your Black Ark for End-Game Campaign Dominance
Most players ignore the Black Ark upgrade tree entirely, but it’s what turns these ships from useful support tools into unstoppable conquest machines. You’ll unlock new upgrade slots as your Black Ark gains experience from battles and raids, with two general upgrade paths to choose from based on your playstyle. The economic path focuses on boosting adjacent province income, increasing slave gains from all activities, and reducing building costs for coastal settlements in its range. That path is perfect if you’re playing a more defensive, territory-focused Dark Elf run.
The military upgrade path unlocks far more aggressive perks, including the ability to recruit elite Dark Elf units directly from the Ark, from Cold One Knights to Black Guard to fully upgraded Hydras. You’ll also get buffs to naval combat strength, larger garrison sizes, and even a perk that lets you replenish adjacent ground army units twice as fast when parked in a coastal tile. You don’t have to stick to one upgrade path – mix and match perks based on your campaign goals. For example, if you’re planning to invade the High Elf homelands, grab the military upgrades first so you can recruit full elite armies right on the coast without shipping them from Naggaroth.
Fully upgraded Black Arks with a level 20+ admiral are almost unbeatable in naval combat. They can take on full stacks of High Elf dragon ships or Dwarf ironclads without breaking a sweat, and they’ll generate enough passive slave income to fund 2 to 3 full ground armies all on their own. I once ran a campaign where I used four fully upgraded Black Arks to conquer every coastal settlement on the map before I even touched any inland territory, and it was one of the easiest legendary Dark Elf runs I’ve ever completed.
Common Black Ark Mistakes to Avoid
Even experienced players make simple mistakes that waste their Black Ark’s potential, and most of them are easy to avoid if you know what to look for. The most common one is leaving your Black Ark parked in your home port for the entire campaign. I’ve seen so many players forget they even have it after the first 10 turns, and they miss out on thousands of extra gold and slaves as a result. Even if you only use it for passive income buffs, it’s worth moving it to your most developed coastal province cluster to get the most value.
Another big mistake is sending an unupgraded Black Ark against high-tier enemy fleets early on. If you run into a full stack of Dwarf ironclads in the first 30 turns, your base Black Ark will get sunk in two or three volleys, and you’ll have to wait 20+ turns to build a new one. Always scout ahead with a cheap hero unit before sailing your Black Ark into unknown waters, and run from any fleet that looks stronger than your current garrison.
Don’t sleep on the recruitment discount, either. All units recruited from a Black Ark are 20% cheaper than units recruited from standard settlements, so if you’re building a new army, recruit 80% of its units from the Ark to save thousands of gold. You can even recruit units to the Ark and then transfer them to a ground army waiting on the coast for no extra cost, which is perfect for building new armies far from your home territory.
Losing a fully upgraded Black Ark can set your campaign back by 20+ turns, so always scout ahead before moving it into unknown waters. It’s easy to get cocky when your Ark is fully upgraded, but even a maxed-out ship can get overwhelmed by three or four full enemy fleets if you get caught off guard. Keep a small escort fleet with it if you’re sailing through hostile territory, just to be safe.
At the end of the day, Black Arks are what make Dark Elf campaigns feel so unique and dynamic compared to every other faction in the game. You don’t have to follow any strict meta to get value out of them, either – even if you just use yours for occasional raids and extra slave income, you’ll notice a huge difference in how smoothly your campaign runs. I’ve used these tricks to beat legendary Dark Elf campaigns three times now, and I still find new little perks of using Black Arks every time I start a new run. If you’ve been sleeping on these floating fortresses, take 10 minutes in your next playthrough to test out the tips we covered here, and you’ll quickly get the hang of how to use Black Arks in Warhammer 2 to dominate every coast on the map. Oh, and one last little tip: if you’re playing as Malekith, you get an extra 10% buff to all Black Ark combat stats, so lean into that hard if you pick his faction.
