Spelunker

Overview

Spelunker is a legacy Episode: Echoes Ritual, Battleground: Echoes triumph. Complete each of the three Act II Battlegrounds on Nessus.

How to complete

Progress the original Act I story to unlock the Battleground activity, then complete Battleground: Delve, Battleground: Conduit, and Battleground: Core as Act II opens their routes.

Finish Delve's encounters with Kalliks, Baron of House Dusk and Hypolydron, Captive Mind, defeat Kamarian, Radial Overseer in Conduit, and finish Core against Antioptes, Hypogean Sentinel. Stay through each activity's result. Repeating only one Battleground does not replace the full set. The original Echoes seasonal story route retired in July 2025.
