Prismatic Recaster
From Destinypedia, the Destiny wiki
The prismatic recaster added a new type of Engram in Destiny 2 in season 12: The Umbral Engram. Rather than going to Master Rahool, players could focus a new type of purple-dark colored Engrams next to the Drifter, at his "kitbashed" recaster.
The new umbral engrams allowed players to specify the types of weapons or armor that they wanted within three different tiers: Each higher tier provided more specific or better-rolled rewards.
