History of Umbral Decoder

Overview

The Umbral Decoder is a device that extracts the Darkness from focused Umbral Engrams and reveals the gear inside; rewards depend on how much was spent focusing at the Prismatic Recaster. It stands in the Annex of The Tower, next to The Drifter, in Season of Arrivals.
