Skull and Bones Guide

Every pirate needs treasure and in the case of Skull and Bones, that takes the form of Silver. Silver is needed to purchase blueprints and to craft new ships, furniture, and weapons. You're going to need a healthy amount of Silver, and there are a few ways to get it. While completing contracts and taking out enemy ships will earn you some Silver, the best way to earn it is by selling commodities.
Commodities are a specific type of item that you can loot or purchase from commodity traders at some outposts. These items sell for a decent amount of Silver, but you can actually sell them for even more, if you head to a region where they are in higher demand. If you zoom out the map to the second highest level, the side tab will display which items are in high demand in the region you are hovering over. Selling those items in that region will net you more Silver, with green arrows shown next to the item on the sell screen.
