Assassin’s Creed IV: Black Flag Devil’s Eye Caverns Chests Locations
The first treasure chest in Devil’s Eye Caverns, is close to the diving bell, inside a shipwreck.
Stay away from the urchins and jellyfishes while diving inside the wreck, and loot the chest to get 169 R and a gold ring (100 Reales).
The second chest is north from the previous one, near an air barrel.
Look for it on the bottom of the ocean, under another shipwreck and loot it to get 279 Reales.
Chest 3 When you reach the northern section of the caverns, you will be able to find the third chest which is protected by a moray eel.
It is also located under a shipwreck and if you loot it you will get 118 Reales and a golden compass (75 R).
Continue to swim north and eventually you will reach another air barrel. Next to it you should see a shipwreck and a glowing hatch.
Open the hatch to get inside and collect the fourth chest which contains 1000 Reales. After you get the collectible, look around for a new tunnel that will take you to the western area of the caverns.
As you swim north you will find the first air pocket. Dive and look around to see the fifth chest near the entrance to the next tunnel you have to follow. Inside the chest you will find 325 Reales.
Chest 6 & 7
The next two chests are on the ground close to each other. You will find them in a cave above the water. One of them contains 273 Reales, while the other one the Elite Swivel Guns Plan.
Once you loot the previous two chests look around for another diving spot and perform a Leap of Faith in the tunnel below.
Dive to find the final chest, and then follow the tunnel nearby to return to the diving bell.
