The Dyadic Perfection quest has you searching for the last batch of Taken Osseous Fragments within The Sunless Cell Strike.
This requires that you explore the areas that you pass until you find all 6 of them, which is required to complete Dyadic Perfection.
To make things easier for you, we have put together all their locations so that you can easily find them within a single run.
All Osseous Fragment Locations in The Sunless Cell Strike
Osseous Fragment 1
The first Taken Osseous Fragment can be found as you are making your way to The Founts after starting in The Mausoleum.
Once you enter the chamber that leads to a path going to The Founts, head straight to the end instead of turning left and you will find it near the bars.
Osseous Fragment 2
Once you reach The Founts, the second Taken Osseous Fragment can be found just as you turn to your right before going further within the area.
Upon reaching The Founts, turn right and look up and you will see the fragment above you, which you can reach using your jump/glide maneuvers.
Osseous Fragment 3
After obtaining Osseous Fragment 2, make your way straight and go down into the underground part of The Founts.
Proceed to make your way through the area until you see a gate with a barrier on your left, which you will head past until you reach the next area.
Turn to your left and check behind the Hive Crate and you will see the Osseous Fragment tucked away in a sneaky spot.
Osseous Fragment 4
Once you progress to the large room where you need to unseal the doors by destroying Taken Orbs within barriers, there will be two sets of stairs.
Take the stairs on the left and look over the edge, which will reveal one of the Taken Osseous Fragments at the end of a platform.
Osseous Fragment 5
In the same area as Osseous Fragment 4, you may reveal hidden platforms by summoning your Ghost and may jump on top of these. (Even if they become invisible)
Use these platforms to get under the bridge until you reach a small platform with a door inside, which is where a fragment can be found.
Osseous Fragment 6
After fighting your way past the room with the large eyes that cause Suffocating Terror where you need to “Clear the Area”, the next Osseous Fragment will be nearby.
Defeat the Consumed Ogre and head into the next room where there is a bridge but before continuing, head up to the platform above and the last fragment will be there.

Verdict
Some of the Taken Osseous Fragments can be hard to spot, which makes it important to look for their glow.
Try to get the two fragments as soon as you can since you will be moved to the next area if your Fireteam advances.
Some of the fragments may be tricky to spot until you are at a certain angle, but their locations are fixed in The Sunless Cell.
