Flameheart’s haunted Sea Forts provide a short on-demand raid for any pirate brave enough to conquer one. Clearing an active Sea Fort of the Phantoms that defend it will give you access to its treasury. Inside the treasury, you will find Gold Piles, Treasure of the Damned, and more for you to plunder!

If you want to know everything there is to know about Sea Forts, including where to find one, active vs. inactive, and how to open the locked doors, check out our guide here!

How to complete a Sea Fort

To complete a Sea Fort, you will need to defeat eight waves of Phantoms.

The first seven waves contain four to five Phantoms you need to extinguish. You will hear the ringing of a bell at the end of each wave, letting you know you’ve destroyed the Phantoms required to complete the wave. After you have battled through seven waves, you’ll then have one more wave to finish.

The eighth and final wave will have you taking down another batch of Phantoms and a Captain of the Fortress! Unlike the Phantoms you’ve been fighting up to this point, the Captain of the Fortress has more health and is more aggressive. Don’t expect him to go down without a fight! You can pick him out of the crowd as he will be the only Phantom with an orange title above his head.

Captain of the Fortress

When you defeat the Captain of the Fortress, he will drop a Fortress Treasury Key. This key opens up the Fortress Treasury on the bottom floor of the Sea Fort.

Also, upon killing the Captain of the Fortress, the fort will no longer repopulate with Phantoms until you leave. So you can take your time moving treasure to your ship and exploring every nook and cranny inside!

The Sea Fort is packed with resources and Ammo Crates to help you during battle. We managed to complete a Sea Fort with a Cutlass and Blunderbuss equipped. Also, be on the lookout for Ammo Pouches that Phantoms drop when killed! The extra ammo will be handy to complete the Sea Fort quickly.

How long does it take to complete a Sea Fort?

The Sea Fort’s difficulty is dependent on the size of the crew who started the encounter. Depending on the crew size, it should take 10 to 15 minutes to complete a Sea Fort and retrieve the key to the treasury.

If you start a Sea Fort with a larger crew, you can expect to battle more challenging Phantoms. They will be more aggressive and have more health.

How much gold does a Sea Fort give you?

Inside the Sea Fort’s Treasury, you will find Gold Piles and around 12k worth of gold.

You can also find dozens of Gold Pouches and other pieces of treasure hidden in cabinets, cupboards, and crates around the Sea Fort. If you have a keen eye, you could earn yourself an extra 2k worth of gold!
