Tips and Tricks to Complete the Triumphs for Destiny 2 ‘The Discerptor’ Title

Thoughtstealer, Solo, and Master

To learn how to beat the Duality dungeon, you can check out the in-depth guide from YouTuber KackisHD above. It’s better that you run these Triumphs with a Fireteam for (much-needed) extra firepower and especially since Caiatl, the final boss of the dungeon, is such a slog to beat. You have to kill the closest Bellkeeper to a Bell that Caiatl is going to ring, and if you time it right, Caiatl will be stunned and anyone nearby will get a damage boost for 10 seconds. While missing a Bell won’t count as a failure, it is still as annoying as it sounds.

Also, don’t forget that there are active modifiers for Master Duality Dungeon:

  • Master Duality: +30 Power over the Pinnacle cap.
  • All Bellkeepers have Void shields.
  • Barrier and Unstoppable Champions are present:
  • First Encounter: Unstoppable Champions
  • Second Encounter: Barrier Champions
  • Final Encounter: Barrier Champions
  • Match Game is active.

Duality Badge and Assassin’s Lament

  • First Encounter: Unstoppable Champions
  • Second Encounter: Barrier Champions
  • Final Encounter: Barrier Champions

To complete Duality Badge Triumph you’ll need to get all the Duality Dungeon items:

Heartshadow Exotic Sword has a 10% drop chance per character every week and you can increase the drop rate by completing the following Triumphs:

  • Solo Thoughtstealer
  • Master Thoughtstealer
  • Mind Heist

Mind Heist

To locate all Calus’s repressed memories, YouTuber Esoterickk has made a pretty handy guide, so I recommend watching it.

Others

The other Triumphs are pretty straightforward. But you might want to check out our Solar 3.0 build guides for Solar Fireteam Completion, United in Secrecy, and United in Class Triumphs. For the last two Triumphs, the health regeneration abilities in a Solar build can be a huge deciding factor when running a Dungeon as tough as Duality:

  • Solar 3.0 Titan build
  • Solar 3.0 Warlock build
  • Solar 3.0 Hunter build

We also have a more general-purpose collection of Titan and Warlock builds for Season 17. Meanwhile, you might want to wait until Arc 3.0 rework is introduced in Destiny 2 Season 18 to tackle the Arc Fireteam Completion to make things easier for you and your friends.
