There are currently three types of flags in the game. Player-crafted flags can be picked up, but the player can't remove Pirate and Merchant flags.
Other types of FlagsEdit
- Pirate Flag: Indicates a Battlemaster Settlement island containing dangerous pirates.
- Merchant Flag: This flag shows that there is a merchant on the island.
- The flag is the only customization item that can only be placed on islands, not on boats.
- Placing a flag on a particularly high mountain lets you complete the "Where everyone can see" Steam achievement.
