Among the many side missions you can complete in Assassin's Creed Black Flag Resynced, one type is known as Naval Contracts. These missions task you with sinking enemy ships or gathering certain materials, which can be obtained by attacking ships or looting warehouses. These missions have difficulty ratings ranging from 1 to 5 stars. The more stars a contract has, the harder it will be and, generally speaking, the better the reward.
