Player Alliance is a mechanic in Sea of Thieves that allows multiple ships to work together and share their loot.
To form an Alliance, a ship must first raise the "Offer Alliance" pennant Flag in the Flag Box. This flag can be recognized by its triangular shape and white and red colour scheme. Only one ship needs to sail the "Offer Alliance" Pennant. After this, any ship in the vicinity of the Alliance Pennant can create an Alliance at their Flag Box. The game will assign a name and flag to the Alliance and players from both ships will see a banner on their screens notifying them that an Alliance has been created, or that a new ship has joined the existing alliance. There is also an option in the flag box to leave the Alliance.
- Up to six ships can be part of a single Alliance.
- When a crew sells treasure , that crew will get 100% of their rewards, while other crews in the Alliance will each receive 50% of the gold value.
- However, Emissary Flags sold to the Reapers Bones, as well as Reapers Chests don't share across Alliances.
- Ships in an alliance are visible to each other on their Map Table.
- Alliance members can place voyages on the voting table for other ships in their alliance.
- Alliance members can also solve Riddle Maps and dig up the treasure on a Treasure Map for other crews in the Alliance.
- When you form an Alliance with another Crew, the allied crews’ nameplates will become Purple to help identify those in your Alliance.
- Alliance crews can still kill, sink and steal from each other.
You can join in an alliance with a ship that's already sunk. Essentially, if the Alliance pennant is still visible above the water and you are in range to join the alliance, you can do it!
