How to unlock all Barrow-Dyad Catalysts in Destiny 2

All Barrow-Dyad Catalysts are now in Destiny 2. But unlike previous episodic Exotic Catalysts, these don’t come from running a mission multiple times. Instead, you’ll need to fulfill some secret conditions.

In this Destiny 2 guide, we’ll walk you through how to unlock all Barrow-Dyad Catalysts in Destiny 2. These quests will net you the High-Impact Reserves, Hatchling, One For All, and Target Lock Catalysts.

This walkthrough assumes you’ve finished the “Dyadic Ascension” quest already to fully upgrade your Barrow-Dyad’s Intrinsic Perk, and also that you’ve collected all Coalescence collectibles.

Update (April): Added the third and fourth Barrow-Dyad catalysts.

How to get the High-Impact Reserves Catalyst for Barrow-Dyad

To get the High-Impact Rounds Catalyst Refit for Barrow-Dyad, you’ll need to complete an Expert version of the Court of Blades activity with the Exotic submachine gun equipped. When the activity ends, you’ll get an Exotic quest called “Sharp Osseous Spine.” Take this quest back to the Shaping Slab in Eris’ apartment and exchange it for the “A Needle’s Path” Exotic quest.

The first step of this quest is to fully rank up the Path of Resolve, getting it to reputation level 12. Complete various episodic activities (wearing the episodic armor gives you a boost here!) to level up until you reach the final level and claim the Moment of Clarity upgrade. If you’ve completed the “Dyadic Ascension” quest already, “A Needle’s Path” will skip to its second and final step.

Once you’ve reached rank 12 on the Path of Resolve and completed the first step, you’ll need to do another Expert level Court of Blades. However, this time, you’re limited to using precision weapons only (plus Barrow-Dyad). Here’s everything that’s fair game to use:

• Scout rifles
• Linear fusion rifles
• Sniper rifles
• Barrow-Dyad

If you complete the Court of Blades on Expert with the proper loadout, the High-Impact Reserves Catalyst will drop from the final chest. Head to The Enclave to re-craft Barrow-Dyad with your new Catalyst.

How to get the Hatchling Catalyst for Barrow-Dyad

To get the Hatchling Catalyst Refit for Barrow-Dyad, you’ll need to find and open a secret portal in the Dreadnaught. There is some contention among the community on what allows you to open this portal, but we recommend you do the following to increase your chances:

• Get the High-Impact Reserve Catalyst Refit for Barrow-Dyad and recraft the weapon with it attached
• Complete the second week of the Act 2 story
• Unlock the Path of Ambition (even if you don’t need to do this for the portal, you definitely will need to do it to get Hatchling, so get it out of the way now)
• Equip Barrow-Dyad when looking for the portal

Once you’ve done everything above, you’re ready for a bit of portal hunting, which is, mercifully, pretty simple. Load into The Nether (ideally the private version so you don’t ruin the experience of any other Guardians) and reload the activity until it starts you in the Trenchway — the area with the Tormentor boss that’s the exterior of the ship.

In the Trenchway, take your Guardian and your Barrow-Dyad and head inside. Cross the big chasm and head to the left side of the platform (where the fire crystal event sometimes spawns). Turn around and look across the chasm to the area you came from, then look up and to the right. On the wall, you’ll see an indent that leads into a secret room.

Walk up to the edge of the platform you’re on and pull out your Ghost. You’ll see a bunch of the invisible Dreadnaught platforms ahead of you. Carefully use the platforms to reach the secret room.

Once you arrive, you’ll see a strange device on the left wall. If you get close, you’ll see a prompt that says “Rites of the Deep Tithe Found Worthy.” If you see this, interact with the device and jump through the Taken portal that appears. Loot both chests and you’ll get a Heavy Osseous Spine, which you can take back to the Shaping Slab to get the “A Hammer’s Path” quest.

Some players have reported issues with getting into the portal due to what appears to be a bug. Destiny YouTuber Skarrow9 has discovered a workaround. Even if you can’t interact with the device, you can enter a friend’s portal and get the Catalyst quest if they open one in their game and you join their instance. We were able to confirm that friends can enter a hosts portal that was opened before they joined.

Once you have “A Hammer’s Path,” you’ll need to reach rank 12 in the Path of Ambition — be forewarned, this is quite time consuming. You can earn reputation by swapping to the Path of Ambition at the Shaping Slab (make sure you do this or you will earn 0 reputation for anything you do) and then completing seasonal activities like the Court of Blades or The Nether.

Once you reach rank 12 and collect all of the Path of Ambition Perks, the quest will ask you to complete an Expert version of The Nether using only close-range weapons. Here’s what you’re allowed to use:

• Shotguns
• Glaives
• Swords
• Barrow-Dyad

Similar to the precision weapon run of the Court of Blades for Barrow-Dyad’s first Catalyst, you’ll receive the Hatchling Catalyst as an activity completion reward as long as you adhere to the loadout requirements listed above. Note that you’ll need to complete the entire Expert Nether, not just the first encounter.

Once you’ve unlocked the Hatchling Catalyst, you can reshape your Barrow-Dyad in Savathun’s Throneworld at The Enclave.

How to get the One for All Catalyst for Barrow-Dyad

To get the One for All Refit for the Barrow-Dyad, the first step is to complete the reprised “Sunless Cell” Strike with the SMG equipped. Completing the Strike will grant you the Trembling Osseous Spine, which you can bring to the Shaping Slab to begin the “A Hundredfold Path” catalyst quest. The first step of this quest is to find all 10 Tithing Wormspawn in the Dreadnaught.

To do this, first make sure you are on the Path of Ambition, which you can set at the Shaping Slab, and make sure the orb is changed to white. Once all of this is done, head to the Dreadnaught and grab the Tithing Worms in the following locations.

Tithing Wormspawn Locations

• Starting in the Trenchway region, go to the outside landing area. At the far end, you’ll find several tall, pointed rocks in a circle, the worm is on top of the central rock.
• Also in the Trenchway, head to the interior of the ship where the giant chasm is. Cross the bridge to the right and continue in that direction. You’ll see a ledge sloping down on your left, and you’ll find the worm at the bottom of that ledge.
• Next, head to the Hall of Souls. In the side room where the Taken are often found gathered around a large Blight, jump on top of the blight to find the worm here.
• Staying in the Hall of Souls, head towards the far end of the area, near the exit to the Mausoleum. Before the exit, look down to the right beneath the platform, and you’ll see some holes in the wall. Jump down to the one on the right and proceed to the end of this small cave to get the worm.
•  At the loading zone for the Mausoleum, immediately go right. Drop down into the lower area, then look up to find a pair of Taken Blights, one large and one small, in the rocks in front of you. The worm here is on the smaller Blight.
• The second worm in the Mausoleum is toward the back of the lower region, on top of one of those blue tentacle-looking things. Use the tentacles to climb up higher, and you should easily spot the worm at the far end of the area, above where the boss of this region would typically appear.
• The next region to search is The Founts. Start by heading to the central chamber with the rotating object in the middle. Head towards the large door at the end of the room, then jump up to the tentacles on the left. Climb up the wall to find a worm nestled among some silver-coloured, veiny blobs. This place is unpleasant to describe.
• To get the second worm in The Founts, go through the ground-level doorway directly below the first one. Follow the tentacles to the right, you’ll find the worm nestled at the back of the room between the tentacles and more veiny blobs.
• Finally, we have the Hull Breach region. From where you enter, turn immediately right and climb up the rocks to find the worm hidden above the door.
• The last worm in Hull Breach is in the far left corner of the area. You’ll see what looks like a cave entrance with a Taken barrier blocking it. Go there, then jump up onto the makeshift awning above the entrance, and you’ll find the worm tucked in the corner behind some rubble.

With all that work done, the only thing left to do is complete the “Sunless Cell” strike again, with only SMGs, Auto Rifles, Machine Guns, and Barrow-Dyad equipped. Once the strike is completed, you will be rewarded with the One for All Refit and a shiny new catalyst for the Barrow-Dyad.

How to get the Target Lock Catalyst for Barrow-Dyad

As with some of the previous Catalysts for this weapon, you’ll need to meet some prerequisites to get your hands on the Target Lock Refit for Barrow-Dyad. The exact details aren’t explained in the game, but it does appear you will need to have all of the Coalescence collectables. They don’t appear in your inventory, but it appears that you need them all for this Catalyst.

Once you’ve found all of the Coalescences, you can access the portal to begin this quest. It can be found in a small room at the back left of the Hull Breach region. This is much the same as the one from the Hatchling Catalyst quest, and if you see a prompt that says “Crossed Blades Tithe Found Worthy”, you can open the portal.

Go through and open the chests to receive the Warped Osseous Spine, which you can bring to the Shaping Slab to begin the A Silken Path exotic quest. The first step of this quest is to find all ten Ravenous Wormspawn, so much like the last Catalyst, we need to do some worm hunting.

Before leaving Eris’ Flat, be sure to change to the Path of Resolve, and make sure the Taken orb is changed to black to begin your search.

Ravenous Wormspawn Locations

• Starting again in the Trenchway, make your way from the landing zone towards the interior entrance. When you get there, turn around and jump up onto the T-shaped structure to find the worm. There are two here; you want the one on the left.
• The second Trenchway worm is in the interior chasm area. Cross the bridge and follow the walkway to the left. The worm is on a ledge directly above the end of the walkway.
• On to the Hall of Souls, start at the Court of Oryx. While facing the portal location here, look left and head towards the entrance to the Trenchway. The first worm here is on a pillar below the platform to the left of this area.
• The second worm in the Hall of Souls can be found by going right instead of left from the Court of Oryx. Head towards the side room, but before entering the room, go to the right. You’ll see parts of the wall curled up, creating a walkway you can jump to. Do so, and follow the path ahead to find the worm at the end.
• Moving on to the Mausoleum, once again take an immediate right turn from the spawn location to head down into the lower area. Just over the little wall to your right, you’ll see a blue tentacle. Jump onto it and then drop down to the rocks below, you’ll find the worm tucked into a small crevice there.
• Back to the starting location in the Mausoleum, go forward towards the far end of the area. On the right side of the room, you’ll see a cluster of glowing yellow blobs on the wall. There is a platform halfway up the wall there. Jump up, and you’ll find a worm.
• Next up is The Founts. From the starting point, go to the left of the twisting object in the center of the room. Jump through the broken window into a room with four rows of three coffin-like objects on the far wall, each with Hive runes on them. Climb up the second row from the right, you’ll find the worm at the top.
• For the second worm in The Founts, start again from the twisting object. Go forward into the second part of this central room, then go through the ground-level door to the right. Hug the wall to your left as you enter, and you’ll find the worm just around the corner.
• Finishing up in the Hull Breach, the first of the two worms here can be found near the massive hole in the hull at the back of this region. Here, you’ll find a gigantic rock structure with three large holes going through it. Use the holes to jump from one to the next, and you’ll find the worm in the third hole.
• The final Ravenous Wormspawn is also at the edge of the Hull Breach region. Go to the hull breach itself at the end of the area, near where the previous worm was found. Go all the way to the right, where a large red spike is sticking outwards at an angle. Look down over the edge and drop down to where you see a small platform. Look up, and you’ll find the worm under the ledge above you.

Once you’ve acquired all of the Ravenous Wormspawn, the last step of the quest is to complete the “Derealize” exotic mission with the Barrow-Dyad equipped. You’ll have already done this mission to get the weapon in the first place, so another run-through shouldn’t be anything new.

You don’t necessarily have to use the Barrow-Dyad throughout the mission, just be sure you have it equipped at the end. So long as you do, you’ll be awarded the Target Lock Refit upon completion.
