How to complete the ‘Dyadic Ascension’ quest in Destiny 2

The “Dyadic Ascension” quest in Destiny 2 is how you’ll unlock the upgraded Intrinsic Perks for the craftable Heresy Exotic, the Barrow-Dyad submachine gun. To unlock these upgrades, however, you’ll need to comb through the Dreadnaught looking for Taken Osseous Fragments in The Nether activity.

If you don’t have access to this quest yet, or the Barrow-Dyad Exotic, make sure you complete “The Taken Path” quest and the “Derealize” mission. “Dyadic Ascension” will be waiting for you at the slab in Eris’ apartment once those are both complete.

In this Destiny 2 guide, we’ll walk you through where to find all of the Taken Osseous Fragments in Heresy, as well as what the “Moment of Clarity” quest step refers to.

Where to find Taken Osseous Fragments in Destiny 2

Steps 2 and 4 of “Dyadic Ascension” ask you to hunt down six and then 12 Taken Osseous Fragments inside the Dreadnaught (these steps are collective, so it’s six per step, not 18 total).

These are little collectibles, similar to the ones you found during “The Taken Path,” and they show up on your radar once you’re close to them — making them easy to spot if you know the general locations, which we’ll give you below. As of this writing, there appear to be 15 of them, five in each of the main Dreadnaught areas.

Steps 1 and 3 require you to unlock certain perks on the Mastery of Resolve reputation track. Step 1 requires you to hit rank 5 with the Shaping Slab, which will net you the “Steel Your Nerves” perk. Step 3 will ask you to hit almost max rank, rank 9, to get the “Unbreakable Will” perk.

Rank 5 is extremely quick to hit, and you should be there, or close to there, if you’ve finished the seasonal story thus far. Rank 9 is a bit more of a grind, but you can manage to get it pretty quickly if you play The Nether and get some of the secret chests inside each time.

Below, we’ll tell you where to find the Taken Osseous Fragments in each of the three main areas. You’ll unlock the Panic Response II and Panic Response III Intrinsic upgrades when you finish steps 2 and 4 respectively.

Hall of Souls Taken Osseous Fragment locations

There are five Taken Osseous Fragments scattered around the Hall of Souls, often in places that are easy to fall off of, so make sure you have revive tokens on hand or Strand grapple equipped.

Hall of Souls Taken Osseous Fragment 1

When you spawn into the Mausoleum from the Trenchway — and you have that long, chitinous bridge — to the left of the main arena, head right and through the doorway. You’ll find a Taken Osseous Fragment hiding behind some of the big stone slabs in the hallway.

Hall of Souls Taken Osseous Fragment 2

After Taken Osseous Fragment 1, through the main weapon chamber with the Tormentor, jump down and back when you reach the next bridge to find a Taken Osseous Fragment resting below the platform.

Hall of Souls Taken Osseous Fragment 3

Across the same bridge for Taken Osseous Fragment 2, past The Ravenous enemy, jump along the big pillars and land on a lip to your right, where you’ll find another Taken Osseous Fragment.

Hall of Souls Taken Osseous Fragment 4

Continue jumping on the slabs from Taken Osseous Fragment 3 and round the corner. Walk forward from where you land, and instead of jumping up to the next platform, look under it to find a cylinder with a Taken Osseous Fragment resting on it.

Hall of Souls Taken Osseous Fragment 5

From Taken Osseous Fragment 4, take a left and run through the next chamber until you reach an exit barred off by Taken energy. Facing the door, look to your left and you’ll find the final Taken Osseous Fragment for this area resting on a pillar.

Mausoleum Taken Osseous Fragment locations

There are five Taken Osseous Fragments in the Mausoleum, including one in the final boss arena.

Mausoleum Taken Osseous Fragment 1

At the back of the area, across from the trench and near the infected ship, you’ll find a Taken Osseous Fragment glowing on top of a pillar.

Mausoleum Taken Osseous Fragment 2

Near the opening of the trench but still on the upper floor, you’ll find a Taken Osseous Fragment hidden under the large tentacle on the left side of the room.

Mausoleum Taken Osseous Fragment 3

Under the elevated platform in the middle of the room, you’ll find the third Taken Osseous Fragment glowing in a corner under the crumbled bridge.

Mausoleum Taken Osseous Fragment 4

Inside the trench, on the way to the final boss, you’ll see a cliff of crystals to your right. There is a Taken Osseous Fragment resting on one of the crystals.

Mausoleum Taken Osseous Fragment 5

In the boss arena, on the right side if you’re facing the Ogre, you’ll find a Taken Osseous Fragment sitting on the back of a rock.

Trenchway Taken Osseous Fragment locations

There are five Taken Osseous Fragments in the Trenchway, including two in the boss’ general area, so be careful as you explore.

Trenchway Taken Osseous Fragment 1

To the left of where the boss is standing, doing his ritual, you’ll see a Taken Osseous Fragment resting on a curled up lip of the Dreadnaught. Jump up the pillar to grab it.

Trenchway Taken Osseous Fragment 2

To the left of Taken Osseous Fragment 1, you’ll find another tucked into some rubble on the ground.

Trenchway Taken Osseous Fragment 3

Inside, where the pair of Subjugators typically spawn, you’ll find a rectangular platform. Jump onto it and you’ll find another Taken Osseous Fragment.

Trenchway Taken Osseous Fragment 4

Across the gap from Taken Osseous Fragment 3, you’ll find a large lip curled up on the wall. Jump up to it to get another Taken Osseous Fragment.

Trenchway Taken Osseous Fragment 5

Inside, on the far right side of the arena, you’ll find the area where Oryx’s throne was back in The Taken King — a circular outcropping. Use the invisible platforms to jump over and you’ll find a Taken Osseous Fragment embedded in a stone pillar.

How to get past the ‘Moment of Clarity’ step in ‘Dyadic Ascension’

Unfortunately, as of this writing, the rest of the quest appears to be time-gated. Step 5’s only step is “Moment of Clarity acquired.”

But if you look below that, it says “Acquire the Moment of Clarity upgrade from the Shaping Slab.” This suggests that, much like the Step 3 of the quest, where it asks you to unlock “Unbreakable Will,” you’ll need to upgrade your reputation with the Shaping Slab in order to proceed. However, the reputation track currently ends at level 10, and there is no “Moment of Clarity” upgrade to get.

Bungie has confirmed, both in public communications and in an email to Polygon, that the “Moment of Clarity” upgrade won’t be available until March 11 when Heresy Act 2 drops.

As of this writing, there is no known information on how to get the four Catalysts for Barrow-Dyad. It’s unclear if these also won’t be available until Act 2 or later.
