How to Get Barrow-Dyad in Destiny 2

Barrow-Dyad is the exotic submachine gun from Episode: Heresy, and Derealize is the only mission that drops it. Update 9.7.0 moved Derealize into Pinnacle Ops under Vanguard Ops, so you launch it straight from the Director with no quest prerequisite, provided you own the relevant content.

How to get Barrow Dyad

Your first Derealize clear drops Barrow-Dyad with Deepsight Resonance. Extract or dismantle that copy to unlock the pattern at the Enclave, then shape it there. It needs a single pattern, so one good clear plus the Enclave step is enough to craft your own.

Catalysts

Barrow-Dyad has four catalysts, separate from its intrinsic upgrades: Target Lock Refit, One for All Refit, Hatchling Refit, and High-Impact Reserves Refit. Higher difficulties inside Derealize pay out catalysts, and reshaping applies them. The intrinsic Panic Response line improves the weapon’s base trait rather than adding a catalyst perk.

Which difficulty to farm

Higher difficulties inside the activity are where catalysts and better rewards drop, but they also ramp the Vrhiisk relic phases. If you are solo, start on a lower difficulty to learn the No Escape puzzle and the relic mechanics before pushing for catalyst drops, because a failed boss phase wastes the whole run.

How it compares

Against other Void SMGs, Barrow-Dyad leans into sustained add-clear rather than burst, so it slots into builds that already plan around its trait. It is not a direct upgrade over every option, but its catalyst flexibility makes it a strong generalist once shaped. The exotic weapons guide lists every source, and how to get exotics covers the paths that actually pay off.

Build notes

Barrow-Dyad is a Void SMG built for add-clear and close-range DPS. It rewards buildcraft around its trait, and it pairs naturally with subclasses that handle the Tormentors and Subjugators in the mission. Bring healing for the Vrhiisk relic phases, which are noticeably harder solo.
