If you’ve ever played a Dark Elf campaign in Total War Warhammer 2 and left your Black Arks sitting unused in coastal waters, you’re missing out on one of the faction’s most overpowered unique mechanics. I spent 30 hours testing different Black Ark loadouts and use cases on my last Legendary difficulty run, and the difference between ignoring them and using them well was night and day. I went from getting pushed back by High Elf naval raids every 10 turns to wiping out entire coastal factions before they even got a chance to siege my settlements. This guide breaks down exactly how to use black arks total war warhammer 2, no convoluted meta tricks required, just actionable steps you can implement on your next playthrough.
Core Rules for How to Use Black Arks Total War Warhammer 2 for Maximum Impact
First, let’s get the basic ground rules out of the way, because a lot of new players treat Black Arks like regular naval ships, which is a huge waste of their potential. Black Arks are mobile, self-sustaining bases that can operate completely independently from your mainland settlements, and leaning into that flexibility is where they shine. Black Arks never need to dock at your own settlements to recruit units, replenish troops, or build new structures, as long as they’re not in an enemy coastal zone of control.
Each Black Ark gets a unique lord that levels separately from your land armies, so you don’t have to waste a high-skill general on naval duty if you don’t want to. You’ll get your first Black Ark for free around turn 15 of a standard Dark Elf campaign, and you can unlock up to 4 total as you conquer specific coastal landmark settlements across the map. I used to waste 5 turns sailing my first Black Ark back to Naggarond every time I needed new units, until I realized I could build a recruitment building right on the ark itself and cut that travel time out entirely.
They also have a 10-slot build queue just like a regular settlement, so you can specialize each one for a specific job instead of trying to make them do everything at once. Trying to fit raiding, recruitment, and naval combat upgrades on a single ark will leave you with no maxed-out bonuses, so pick one role per ark and build for that exclusively.
Best Unit Loadouts for Every Black Ark Role
Once you’ve picked a role for your Black Ark, you can tailor its unit roster and build upgrades to match that job perfectly. I’ve tested dozens of loadouts across 6 different Dark Elf campaigns, and these three setups work for 90% of common play scenarios, no matter what difficulty you’re playing on:
- Raiding-focused loadout: 6 units of Dark Riders (crossbow), 4 units of Shades, 3 units of Cold One Knights, 2 units of Black Guard, 5 cheap naval ram ships. This setup lets you hit unprotected coastal settlements, steal thousands of gold in slaves and loot, and escape before enemy land armies can reach the shore. The fast cavalry units can wipe out settlement garrisons in minutes, and the cheap ram ships let you escape any small naval patrols that try to intercept you.
- Invasion support loadout: 4 units of Doomfire Warlocks, 6 units of Darkshards, 3 units of Repeater Bolt Throwers, 2 Hydras, 4 units of Corsairs, 2 high-tier naval combat ships. This loadout is designed to reinforce your land armies during coastal sieges, providing extra artillery and mobile flanking units that don’t take up slots in your main army. You can also use the ark to replenish your land army’s troops after a big battle without waiting 3 turns in a captured settlement.
- Naval dominance loadout: 8 high-tier Black Ark frigates, 4 units of Scourgerunner Chariots, 3 units of Harpies, 3 units of Dark Elf Assassins. This setup lets you wipe out entire enemy naval fleets in one battle, and intercept trade routes to steal thousands of gold per turn without ever touching land. The assassins can also be sent to sabotage enemy coastal settlements to weaken their garrisons before your raiding parties hit.
You don’t have to stick to these exact numbers, of course. If you’re fighting a lot of melee-heavy factions like the Lizardmen, swap a couple of ranged units for more Black Guard to hold the line during boarding actions. I usually keep one raiding ark and one invasion ark active for the first 50 turns of my campaign, then add a naval dominance ark once I start expanding across the great ocean.
How to Pair Black Arks with Your Land Campaign Operations
Most players only use Black Arks for naval fights, but their biggest strength is how well they support land-based expansion, especially for the Dark Elf faction that relies on constant raiding to keep slave numbers high. First, when you’re planning to siege a coastal settlement, park your Black Ark just outside the settlement’s zone of control 2 turns before your land army arrives. The ark’s global support aura will give all your land units a 15% attack and defense buff during the siege battle, which can make the difference between winning a siege on the first attempt and losing half your army to garrison archers.
After you capture the settlement, you can use the Black Ark to recruit extra garrison units without spending build slots in the new settlement, so you can move your main army on to the next target faster. You can also park a raiding ark just off the coast of an enemy faction’s territory to generate constant slave and gold income, even if you’re not actively at war with them yet. The raiding income won’t trigger a war declaration, so you can build up your strength for a few turns before you launch a full invasion.
If you’re dealing with constant naval raids from the High Elves or Vampire Coast, park a naval dominance ark in the middle of your coastal trade routes. It will automatically intercept any raiding fleets before they can hit your settlements, and you won’t have to waste time moving land armies around to deal with small raiding parties. I once saved over 20,000 gold in lost settlement income in a single turn by doing this, after spending months getting frustrated by constant High Elf raids on my northern Naggarond ports.
Common Black Ark Mistakes to Avoid on Higher Difficulties
Even if you have the perfect loadout, a few common mistakes can make your Black Arks way less effective, especially on Legendary difficulty where you can’t reload saves to fix bad decisions. First, don’t send a Black Ark into a coastal zone controlled by multiple full enemy land armies. Even the strongest Black Ark garrison can’t beat 2 or 3 full land armies if they all attack it at once from the shore, and losing a fully upgraded Black Ark can set your campaign back 15 turns or more.
Second, don’t waste skill points on your Black Ark lord’s land combat skills if you’re only going to use that ark for raiding or naval fights. Focus on naval combat, recruitment cost reduction, and raiding income bonuses first, those will give you way more value across the whole campaign. You can respec your lord later if you decide to switch the ark’s role, but it’s a waste of gold to do that unnecessarily.
Third, don’t forget that Black Arks can be used to move your land armies across the map for free, without paying the extra movement cost for embarking and disembarking. I’ve used this trick to launch surprise invasions on High Elf islands that were 20 turns away from my nearest mainland settlement, catching them completely off guard before they could build up their garrisons. A lot of players miss this feature entirely, and it’s one of the most useful parts of owning multiple Black Arks late game.
At the end of the day, Black Arks are one of the most unique and fun mechanics in the entire game, and they’re a big part of what makes Dark Elf campaigns feel so different from every other faction. You don’t have to follow every tip in this guide to the letter, but even making small changes to how you deploy and equip your arks will make a huge difference in how easy your campaign is.
