Void Fireteam Completion

Overview

Void Fireteam Completion is a Duality dungeon triumph worth 15 Triumph score. Complete each of its three encounters with a full fireteam using Void subclasses. The reward is score, not Glimmer, and the triumph does not directly award a weapon.

Completion

1. Access Duality with The Witch Queen Dungeon Key and the A Single Thread quest from Suraya Hawthorne. Assemble three players using Nightstalker, Sentinel, or Voidwalker; different character classes are allowed.
2. Defeat Nightmare of Gahlran, Sorrow Bearer. Collect the matching standards, open the corresponding doors, clear the shades, and return to the boss for damage. Defeat Bellkeeper enemies and gather at the return bell before the Nightmare timer expires.
3. Unlock the vault by collecting the standards shown on its floor and defeating the three successive Cabal Nightmare bosses. Keep everyone on Void for each encounter completion.
4. Defeat Nightmare of Caiatl, Princess-Imperial. Deposit four standards to start damage, kill the Bellkeepers, and ring the bell she approaches while the team stands nearby. Repeat the damage sequence until she falls.

Use Void abilities for survival and add clearing, but your weapons do not have to deal Void damage. Keep the required subclasses equipped through encounter completion; this is a fireteam subclass condition rather than a Void final-blow objective.
