Barrow-Dyad is a craftable Exotic SMG you can earn in Destiny 2’s
Heresy season. It’s a Taken-themed SMG that fires Blighted projectiles as you damage targets. It hits incredibly hard, fills a similar niche to Quicksilver Storm, and has a ton of customization options.

Some of those options come in the form of catalysts, additional perks you can forge onto the weapon to improve its performance. There are four catalysts in total for Barrow-Dyad, some of which drastically improve its damage output or general utility. Today, we’ll be going over how to unlock every Exotic catalyst for the Barrow-Dyad SMG.
Barrow-Dyad Catalyst – High-Impact Reserves
Quest |
A Needle’s Path |
---|---|
Activity |
Court of Blades |
Perk |
High-Impact Reserves |
The first catalyst for Barrow-Dyad is unlocked by completing an Expert
Court of Blades
run with Barrow-Dyad equipped. You’ll gain access to this activity at the start of Act 2 of Heresy’s seasonal storyline. We also believe you need to be at Rank 12 of the Shaping Slab while on the Path of Resolve to get this quest to drop, but we can’t confirm this for certain.
If you meet these conditions, then completing the Court of Blades run will drop “A Needle’s Path,” a quest that will award High-Impact Reserves as a craftable trait for Barrow-Dyad. You’ll need to complete another Expert Court of Blades run with a long-range loadout—Scout Rifles, Linear Fusion Rifles, and Sniper Rifles. Barrow-Dyad must also be equipped to complete this step.
You can wait for the timer to expire in your Court of Blades run to spawn the final boss. Melt the boss with your Heavy weapon or Super to unlock your new catalyst trait.
Barrow-Dyad Catalyst – Hatchling

The Nether |

Hatchling |
Barrow-Dyad’s second catalyst is found in
the Nether activity
, located inside The Tenchway tileset. Once you load into the tileset, run inside the Dreadnaught and head towards the cluster of spores in the corner of one of the platforms. Once there, pull out your Ghost to reveal a series of hidden platforms. Hop across the platforms until you reach the gap in the wall.
Some players are unable to interact with the device that activates the catalyst portal. If this is impacting you, join a fireteam with someone who can open the portal for you.
Interact with a device on the left wall to summon a portal to a series of chests. This will give you the quest for Barrow-Dyad’s Hatchling Catalyst. You’ll need to complete two steps:
- Reach Rank 12 with the Shaping Slab while on the Path of Ambition.
- Complete an Expert Nether run with Barrow-Dyad equipped and two close-range weapons—Shotguns, Glaives, and Swords.
