The number of Spoils of Conquest you can earn per raid in Destiny 2 varies depending on the raid. For example, in the King’s Fall, Vow of the Disciple, and Vault of Glass raids, you can earn five Spoils of Conquest for each encounter completed and an additional five for each hidden chest you find. However, legacy raids might offer fewer spoils per encounter and none for the chests. Thus, the total spoils can range significantly based on the raid and your ability to access all encounters and chests.
