History of Dyadic Perfection

Dyadic Perfection is the final Exotic quest for the Barrow-Dyad. It is offered at the Shaping Slab after Dyadic Ascension is complete. Its reward is the fifth and final intrinsic upgrade for the Barrow-Dyad.

Overview

The quest is given at the Shaping Slab once the Guardian has finished Dyadic Ascension and the episode story has unlocked The Sunless Cell strike. It has two objectives, both short.

Walkthrough

1. Collect six Taken Osseous Fragments in The Sunless Cell strike. Fragments are spread through the strike: near the start between The Mausoleum and The Founts, in the room before the central room of The Founts, and several in The Asylum, including one under the central platform where you enter. The last is just past the room with the Subjugator and Ogre.
2. Max the Path of Ambition track at the Shaping Slab. Destinypedia lists three Path of Ambition upgrades to complete for this step.

Rewards

• The fifth and final Panic Response intrinsic upgrade, which improves the Barrow-Dyad's stats.

Trivia

The quest is listed on Destinypedia as a stub without a full walkthrough. The guide used here is dated April 2025, so fragment positions and rank requirements may have changed since.
