History of Unidentified Radiant Frame

Overview

The Unidentified Radiant Frame must be crafted in the Bergusia Forge. It is the last stage of the Black Armory quest for Izanagi's Burden: complete Lock and Key in the European Dead Zone, a final forge fight against a boss that needs drone destruction and sustained damage. Earlier steps include Dul Incaru in the Shattered Throne and Unidentified Frame.

The forge series is old content; Izanagi's Burden is also purchasable from the Monument to Lost Lights per Shacknews.
