History of Umbral Engram

Overview

Umbral Engrams are darkness-infused Legendary engrams introduced in Season of Arrivals, which can be focused to choose reward types. After finding Eris Morn on Io, players decrypt them with the Umbral Decoder and the Drifter's Prismatic Recaster. The first three each week were free; others cost Altered Element (50 to 250) and a Trace Override.
