History of Lightning Round

Overview

Lightning Round is a Triumph in Destiny 2 that requires the completion of all encounters within the Sundered Doctrine dungeon using a full fireteam of Arc subclasses. The triumph awards 15 Triumph Score. It is one of the records counted toward the Delver title for the same dungeon.

How to complete

The Sundered Doctrine dungeon is for one to three players and requires the Dungeon Key. Your whole fireteam must use Arc subclasses for the entire run. The three encounters are:

1. Riddle: Read the missing glyphs in the central sentence. For each one, kill the active Truthspeaker, then route a lens beam from an unused source to the matching target plate. This runs in three rounds of one, two, then three truths. A wrong target summons a Tormentor, so reset and rebuild the route.
2. Zoetic Lockset: Four Shriekers read four wheels. Spend Resonance Splinters to move each wheel's glyph, then lock Stop three times and Kill last. Once the Shriekers' shared health bar is exposed, damage them. Afterward, push the loose core into its receptacle to open the exit.
3. Kerrev, the Erased: Defeat the Truthspeaker to learn which three-glyph column is true. Light all three glyphs in the false column and leave the true column dark. Then activate the console from behind a pillar, survive the burn, and damage Kerrev while avoiding its pulls and the second burn.

Tips

• Learn the official glyph names in the gallery behind the first rally area, and agree on calls before starting.
• Assign Reader, Mechanic and Control roles. Solo players should perform these jobs one at a time.
• Plan lens routes backward from the target while the source is inactive. Energized lenses break after their third rotation.
• Area-of-effect damage does not activate pyramid switches, so aim at the crux.
• Drowning Labyrinth steps must be completed in the same instance as the final boss clear.
