History of Raid Engram

A Raid Engram is an Engram redeemed for Raid loot. During the Leviathan raid era, Benedict 99-40 sold raid armor and weapons each week, in exchange for Emperor Calus Tokens, and a player had to complete the source raid before buying an item. Ghost Primus, a Legendary Kinetic Auto Rifle that dropped as random loot in Leviathan, is also listed as redeemable with Benedict. The sources differ on this point, so check the in-game vendor. Clan Raid Engrams are earned weekly by completing activities as a clan, and they are not sold by Suraya Hawthorne according to the Destiny 2 Wiki, while another source says they could be obtained from her.
