The Barrow-Dyad Catalysts have finally started to arrive in Act 2 of Destiny 2: Heresy. But unlike previous episodic Exotic Catalysts, these dont come from running a mission multiple times. Instead, youll need to fulfill some secret conditions.In this Destiny 2 guide, well walk you through how to unlock the first Barrow-Dyad Catalyst in Destiny 2. This Catalyst is called High-Impact Reserves. Barrow-Dyad can also have the The Hatchling, One For All, and Target Lock Catalyst Refits, but theyre currently unavailable in-game.This walkthrough assumes youve finished the Dyadic Ascension quest already to fully upgrade your Barrow-Dyads Intrinsic Perk. How to get the High-Impact Reserves Catalyst for Barrow-DyadTo get the High-Impact Rounds Catalyst Refit for Barrow-Dyad, youll need to complete an Expert version of the Court of Blades activity with the Exotic submachine gun equipped. When the activity ends, youll 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 Needles 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 youve completed the Dyadic Ascension quest already, A Needles Path will skip to its second and final step.Once youve reached rank 12 on the Path of Resolve and completed the first step, youll need to do another Expert level Court of Blades. However, this time, youre limited to using precision weapons only (plus Barrow-Dyad). Heres everything thats fair game to use:Scout riflesLinear fusion riflesSniper riflesBarrow-DyadIf 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.When will the other Barrow-Dyad Catalysts be available?The other Barrow-Dyad Catalysts will become available as Heresy continues in Destiny 2, but as of this writing, are not yet available.Its possible that one or more of the missing Catalysts could be hidden in Act 2 or even time-gated until Act 3 begins on April 1. Based on how theyre organized in the crafting menu, it seems that after High-Impact Reserves (detailed above), well get the other three Catalysts in this order: Hatchling, One For All, and Target Lock.Well update this guide with instructions on how to get the other Catalysts as they release.
