Riddle

The Riddle is the first encounter of Sundered Doctrine, the Dungeon in Destiny 2: The Final Shape. It is a light-lens symbol puzzle.

The opening room has two symbols on the wall and one blank slot. Defeat the Truthspeaker, a special Grim enemy in one of the side rooms, to find the missing symbol. Defeat Subjugators in each room to collect Lenses, then place them in empty Holsters to reflect the light beam along a chain. Aim the reflected beam at the wheel that shows the correct symbol. Hitting the wrong wheel spawns a Tormentor, and turning off the central light makes the Lenses disappear and resets progress.

The puzzle has three rounds. Round one requires lighting one wheel, round two requires two, and round three requires three. Each new symbol means finding the Truthspeaker again. There is no time limit.
