There are many side quests in Assassin’s Creed IV: Black Flag that give you some spending money. This is good, because upkeep on the Jackdaw, your hideouts, and your crew can get expensive. One side mission you can do to get some extra Reales is find warehouses all across the map. These guarded warehouses have some pretty sweet rewards inside, so plundering them is worth your while. Learn more about finding these buildings below.
The warehouses are all guarded fairly heavily. You will need to take them out in order to get the rewards inside. However, you can get a bonus for being stealthy while taking over the warehouse. Keep this in mind before you rush in. You may want to wait until you get the blowpipe before you start attacking the warehouses.
Only three warehouses will be available to be plundered at a time. One you loot one, another one will unlock shortly after.
