Mission

Battleground: Delve

Descend into Nessus and explore the Vex structures within.

Overview

First of the Episode: Echoes Battlegrounds missions: a 1-3 player Strike-style activity on Nessus launched via Battleground: Echoes (or its Expert version, Battleground: Echoes (Expert)). It is also step one of the "A Rising Chorus" Act 2 quest (Delve, then Battleground: Conduit, then Battleground: Core).

Encounters

Guardians spawn at the Well of Echoes and kill marked Fallen to collect data that drops barriers. Fallen of House of Dusk and Vex of the Nessian Schism oppose you. The finale is a dual-boss arena: Kalliks, Baron of House Dusk (shielded by Siphon Servitors, remove those first) and the freed Vex Hydra Hypolydron, Captive Mind. A specimen collectible sits beside the second planetary piston.
