History of Reflection Detection

Overview

Reflection Detection is a legacy Episode: Echoes triumph in Ritual, Encore. Drop the data partition by completing the final Coda secret-chest puzzle.

How to complete

During the original Act III progression, reach Encore: Coda and unlock the Ancillary Transit Nexus through its conflux puzzles. Use the Ishtar Research Facility portal hub to reach the newly available puzzle containing ruins behind a Vex barrier.

Defeat the enemies carrying Connection Modules and place the modules in the indicated nodes. Defeat the Uplifted Choral Minotaur, collect its Arc Cranium, and fire through the plates to destroy the targets within the barrier. Repeat module placement and cranium shots until every target is destroyed.

The barrier disperses and the secret chest becomes available; collect it to complete the puzzle. The original Echoes seasonal route retired in July 2025.
