Don’t cross the bridge; instead, look up and to the right attached to the large pillar.

It’ll appear like our image above.

If it’s not there, close and reload the activity.

The hidden path to the Blight.

The Trenchways

The Blight in the Trenchways is the easiest one to find.

From the spawn area, head straight towards the Tormentor that’s participating in the ritual near the columns.

The Blight will be near the wall.

The symbol and its corresponding directive message

You’ll see a Taken Osseous Fragment in a stone bowl: collect it.

This is a tier three Runic Enhancement.

Lost Sector Blights

Head to the K1 Revelation Lost Sector in Sorrow’s Harbor.

The Taken Osseous Fragment

There, you’ll see a Blight leading to a plate, similar to the one from the Nether.

Repeat this process in the Forgotten Shore Lost Sector, Veles Labyrinth.

The Blight will be in the maze area.

Derealize Exotic Mission

Curse Quests

After completing the two Lost Sectors, return to the Slab in the Last City.

In each area you will find a Taken Relic.

Killing enemies will extend the timer that it shows.

Derealize Quest Entrance

Once an area opens up allowing you to do so, dunk the Taken Relic.

After doing this, you’ll need to head back into the Nether activity again.

This will spawn a mini-boss.

Taken Osseous Fragment 1 - The Hall of Souls

After defeating it, another Taken Osseous Fragment will be yours to collect.

Only after completing all of the steps will you begin the Exotic quest itself, named Derealize.

After empowering the curse with the Relic, the mini-boss can be damaged.

Taken Osseous Fragment 2 - The Hall of Souls

Repeat the process to take down the boss and enter another phase of seeking out Blights which contain symbols.

After completing it once, another quest begins which allows you to get intrinsic upgrades for Barrow Dyad.

Take note that you oughta be at least rank nine at the Slab for this to be achievable.

Taken Osseous Fragment 3 - The Hall of Souls

Barrow Dyad Exotic SMG

The Barrow Dyad Exotic SMG is a strange-looking weapon.

When it’s not firing, Blight depletes, and the weapon’s magazine is gradually refilled.

Reloading it converts stored Blight into Blighted Seekers which track enemies and cause huge amounts of damage.

Taken Osseous Fragment 4 - The Hall of Souls

After following the guide above and obtaining Barrow Dyad, pick up the Dyadic Ascension quest from the Slab.

The quest tasks you with finding more Taken Osseous Fragments in the Nether.

There are currently six available in each area.

Taken Osseous Fragment 5 - The Hall of Souls

As the quest is currently time-gated, you only need to collect 12 Fragments right now.

Continue forward until you find a bridge to the right leading to a higher platform.

Underneath that platform, there is a ledge you oughta jump to and collect the second Fragment.

Taken Osseous Fragment 6 - The Hall of Souls

From there, jump back towards the bridge and follow the room’s left wall from your current perspective.

Soon, to your left you’ll spot some columns.

From the third Fragment, jump to the next column and then to the platform on the left.

Taken Osseous Fragment 1 - The Trenchway

Look down and to the right for another ledge with the fourth Fragment on it.

Find your way back up to the bridge above the platform with the fourth Fragment on it.

Head through the passageway to the area that usually opens the King’s Fall raid.

Taken Osseous Fragment 2 - The Trenchway

From there, continue forward and through the passageways, past the large Blight.

Underneath the platform, on the left is the final Fragment in the Hall of Souls.

The Fragment is on a ledge to the right of the Taken wall.

Taken Osseous Fragment 3 - The Trenchway

From there, jump down from the ledge and continue in the same direction.

There is a hollowed out structure next to a large white wall.

The third Taken Fragment is inside.

Taken Osseous Fragment 4 - The Trenchway

Turn back on yourself and head back towards the spawn area.

Continue through the narrow, white corridor past the Dread enemies.

Jump up on to the ledge that overlooks the crossing area.

Taken Osseous Fragment 5 - The Trenchway

To your left is the fourth Fragment.

From the fourth Fragment, head across the crossing and to the left.

Jump up the wall’s structures and head back towards the center.

Taken Osseous Fragment 6 - The Trenchway

Almost opposite the fourth Fragment is the fifth one, sitting on a triangular jutted-out ledge.

Turn to face the opposite platforms and take out your Ghost to see some hidden platforms.

Use these to cross to the other side.

Taken Osseous Fragment 1 - The Mausoleum

Attached to the back of a large, spiked rock formation is the final Fragment in the Trenchway.

Jump down and to the right to find the first Fragment.

Turn back and follow the rocks back to the spawn point.

Taken Osseous Fragment 2 - The Mausoleum

Jump across the cavern, past the Taken enemies, and underneath the largest central platform.

On the right is the second Fragment.

Continue to the larger, green central area.

Taken Osseous Fragment 3 - The Mausoleum

Jump up the structures in the center.

The third Fragment is on the tallest structure.

Turn back towards spawn and follow the room to the left side.

Taken Osseous Fragment 4 - The Mausoleum

With the flying Dread enemies to your left, the fourth Fragment is under the large tentacle-like structure.

Continue in the same direction, and follow the rocks along the left side of the arena.

With a large gap, on the right is an even bigger rock formation.

Taken Osseous Fragment 5 - The Mausoleum

Roughly in the middle of this is the fifth Fragment.

Continue in the same direction as before, but jump down towards the pools of Taken energy.

Due to its coloring, it blends in.

Taken Osseous Fragment 6 - The Mausoleum

You’ll need a Moment of Clarity upgrade from the Slab which isn’t currently available.

This suggests there could be as many as six catalysts for Barrow Dyad.
