Dungeon: Sundered Doctrine

Overview

Dungeon: Sundered Doctrine is a Triumph associated with the Sundered Doctrine dungeon. It is the last of the ten triumphs that unlock the Delver seal. It is completed by earning the dungeon's trophies, which are its weapons, armor and collectibles.

How to complete

1. Unlock the dungeon. Complete the Final Shape campaign and own either the Final Shape Deluxe Edition or the Final Shape Dungeon Key. Open the destination menu on Savathûn's Throne World and select the activity, which takes place on Rhulk's pyramid ship.
2. Start the quest first. Talk to Ikora Rey in the Tower and pick up "The Drowning Labyrinth" before launching. The quest progresses per character, so do its steps on the same Guardian.
3. Collect every trophy. Keep clearing the dungeon until you have every weapon and armor piece it drops. The Delver title is tied to collecting the full set from the dungeon.

1. The Sundering: complete the dungeon.

Encounter tips

• Riddle (first encounter): kill a Truthspeaker in a side room to get a symbol, then find the wheel with the matching symbol. Subjugator enemies drop lenses that redirect the light onto the symbol plates. Expect three rounds. Assign one player to lens placement and rotation while the others handle adds. Each lens can be rotated only three times before it shatters, and a beam sent to the wrong plate summons a dangerous Tormentor.
• Shrieker boss (second encounter): start with the rightmost wheel and set it to STOP. The suggested order is STOP, STOP, STOP, KILL, which leaves the most time for damage. Linear fusion rifles are a strong choice for damage.
• Kerrev, The Erased (boss): write the six wheel symbols in chat so no one has to memorize them. The symbol the Truthseeker drops decides which side of the wheel to darken and which to light. Lighting the "truth" symbols resets the encounter. Hide behind a pillar when you activate the main wheel to avoid the arena-wide burn that lowers the boss shield. Divinity helps the team land critical hits.

Rewards

• The Delver seal and title.
• Military Doctrine also grants the Future Proof Exotic sparrow. Lonely Travels, Military Doctrine and Laboratory Inspector each raise the initial drop rate of Finality's Auger.
• The Sundering grants an Unsounded Legendary emblem.
