History of Raid Engram

A Raid Engram is an Engram redeemed for Raid loot. For the Leviathan raid, raid engrams were redeemed with Benedict 99-40, and Clan Raid Engrams could be obtained from Suraya Hawthorne. Ghost Primus was one weapon obtainable this way, alongside random raid drops. Sources checked cover only the Leviathan-era use; later raids use different reward systems.
