Terraformed Secrets

Overview

Terraformed Secrets awards 15 triumph score for looting both hidden chests in Root of Nightmares. It contributes to Dream Warrior and unlocks Oxidized Lead.

Locations

1. Between Cataclysm and Scission, leave the main traversal path and climb to the side room guarded by a Tormentor. Defeat the enemies and loot the chest.
2. Between Scission and Macrocosm, continue through the jumping section to the first door requiring the full fireteam. In the following large area, climb the steps and look over the right edge for a Darkness crux below. Shoot it, then return toward the entrance and climb to the high wall room it opens.

Loot both chests yourself. The separate guaranteed Deepsight weapon puzzle is not one of these two checkboxes.
