Elementary, My Dear

Overview

"Elementary, My Dear" is a Triumph in Destiny 2 that is listed among the secret triumphs. It asks you to complete a timed Deepsight puzzle, and its objective counts the Deepsight chests you open. It awards 25 Score.

How to complete

1. Find a timed Deepsight puzzle. Players report that you click a Deepsight to start it.
2. Open the chest the puzzle reveals. The chest is either behind a newly exposed hidden nook or at the end of newly revealed platforms that you need to jump to.
3. Finish the puzzle inside its time limit. Each chest opened from a puzzle counts toward the objective.
4. If no puzzle appears, returning to orbit and re-entering the area has been reported not to bring one back.

Tips

• The companion triumph Disbelieve asks for chests opened from timed Deepsight puzzles, so the two progress together.
• Some players report that progress did not update even after the puzzles were finished, and that some puzzles never appeared for them.
