History of Burning Together

Burning Together is a triumph (15 points) in the Unleashed seal: complete all encounters in the Vesper's Host dungeon with a full fireteam of Solar subclasses.

How to complete

1. Form a full fireteam of three Guardians, all on Solar (Dawnblade, Sunbreaker, Gunslinger) subclasses; do not leave the activity.
2. Encounters: awaken Vesper Station (collect Nuclear Cores from the Heart, Lungs and Brain rooms using Scanner and Operator augments), defeat Raneiks Unified (shoot numbered panels 1-9 in sequence, using Suppressor augments to stun) and the Corrupted Puppeteer (all mechanics combined, with lightning during damage).
3. Needs Destiny 2: The Final Shape plus the dungeon key/Deluxe Edition and the Rogue Network quest from Spider.

A search snippet describes it differently ("on Master difficulty"), which is probably the Stationmaster triumph; the game text above is authoritative.

Rewards
