As you advance through Pirates of the Caribbean Online, you will encounter special Quests giving you the ability to pursue unique Treasure Collections. To complete each collection, you'll need to find a series of elusive items –– often held by deadly foes. Some may find some treasure buried. You can find a buried treasure by accident, or a townsperson may tell you where to look. There are chests of riches hidden all over the Caribbean, so keep an eye out for green circles on the ground. If you see one, start digging!
