Destiny 2: Heresy – How To Unlock The One For All Catalyst For Barrow-Dyad
The Destiny 2: Heresy expansion has introduced a wealth of new weapons, activities, and secrets for Guardians to uncover. Among the most coveted rewards is the Barrow-Dyad, a kinetic pulse rifle that combines precision and versatility. However, its true potential is unlocked through its exotic catalyst, One For All, which enhances its damage output and synergizes with fireteam play.
If you’re eager to maximize this weapon’s power and dominate in PvE and endgame content, this guide will walk you through every step to unlock the One For All Catalyst. To learn more here about the Barrow-Dyad’s base perks and how it fits into the Heresy meta, check out Bungie’s official weapon database.
What You Need Before Starting
Before pursuing the One For All Catalyst, ensure you meet these requirements:
- Own the Heresy Expansion: The Barrow-Dyad and its catalyst are exclusive to the Heresy DLC. If you haven’t purchased it, visit the Eververse store or platform marketplace to acquire it.
- Unlock the Barrow-Dyad: Obtain the weapon by completing the “Echoes of the Fallen” questline on Europa. This quest involves defeating Hive lieutenants, collecting encrypted fragments, and surviving a showdown against a Lucent Hive Lightbearer.
- Reach Power Level 1810+: The catalyst quest involves high-difficulty activities like Master Dungeons and Legend Lost Sectors. Grind Powerful and Pinnacle gear from weekly challenges to reach this threshold.
- Fireteam Readiness: Some steps require teamwork in Nightfalls or Raids. Use LFG platforms like the Destiny 2 Companion App or Discord servers to find reliable teammates.
1: Activate the Catalyst Quest
The One For All Catalyst quest, “Strength in Unity,” isn’t handed out automatically. Follow these steps to trigger it:
- Visit the Tower: Speak to Banshee-44, who will mention rumors of an “ancient pact” tied to the Barrow-Dyad. This dialogue only unlocks after you’ve completed the Heresy campaign.
- Complete a Weapon Proficiency Task: Get 250 final blows with the Barrow-Dyad in any activity. Focus on Altars of Sorrow or the Vanguard Ops playlist for efficiency. For faster progress:
- Use mods like Harmonic Siphon to generate Orbs on rapid kills.
- Equip armor perks that boost pulse rifle ammo reserves or reload speed.
- Return to Banshee: He’ll decrypt a cryptic message pointing you to the Cosmodrome. This triggers the next phase of the quest.
2: Uncover the Hidden Quest in the Cosmodrome
Head to the Cosmodrome and follow these objectives:
Locate the Forgotten Outpost:
- Fast-travel to The Steppes and head northeast toward a collapsed bunker (coordinates: X-12, Y-7). Look for a rusted door marked with Hive runes.
- Clear the Hive enemies guarding the entrance to access the bunker.
Solve the Symbol Puzzle:
- Inside the bunker, interact with a terminal displaying three symbols: A Serpent (Hive), A Pyramid (Darkness), and A Shield (Alliance).
- Input the sequence Shield > Serpent > Pyramid to unlock a hidden chamber.
- Lore Insight: This sequence reflects the alliance between humanity and the Eliksni (Shield), their conflict with the Hive (Serpent), and the looming threat of the Witness (Pyramid).
Retrieve the Catalyst Fragment: Claim the Unity Shard from the chamber. This item starts the next phase.
3: Complete the “Bonds of Fire” Mission
The Unity Shard unlocks a new mission, “Bonds of Fire,” accessible via the Cosmodrome map. Here’s how to clear it:
Defeat the Hive Guardians:
- The mission throws waves of Lucent Hive at you. Use the Barrow-Dyad’s precision shots to break their Ghosts.
- Prioritize Lucent Swordbearers—they’re aggressive but vulnerable to Stasis crowd control.
Activate the Conduits:
- Three Hive totems must be charged simultaneously. This requires a fireteam—assign one player per totem.
- Communicate via voice chat to synchronize activations. Failure triggers a wipe mechanic.
Boss Fight: Kr’axesh, the Bound:
- Mechanics: Kr’axesh summons immune Hive Knights. Destroy their linked shields first.
- Damage Phase: Focus on his crit spot (head) while avoiding AoE blights.
- Reward: The Catalyst Core drops upon victory.
4: Charge the Catalyst Core
The Catalyst Core needs to be charged through specific activities:
Generate Orbs of Power: Create 500 Orbs using the Barrow-Dyad.
- Equip mods like Harmonic Siphon (generates Orbs on rapid kills) and Reaper (Orbs on class ability use).
- Farm the Shuro Chi checkpoint in the Last Wish raid for mass enemy spawns.
Defeat Champions: Eliminate 50 Champions in Nightfalls or Legend/Master Lost Sectors.
- Focus on Disruptor Rounds or Anti-Barrier Pulse Rifle mods to stun Champions efficiently.
Complete a Master Dungeon: Finish The Shattered Spire or any Heresy-era dungeon with the Barrow-Dyad equipped.
- Recommended Loadout: Pair with a void machine gun for add-clear and a solar fusion rifle for boss DPS.
5: Forge the Catalyst at the Enclave
Return to Mars and use the Enclave’s Relic to finalize the catalyst:
Shape the Catalyst: Insert the charged Catalyst Core into the Barrow-Dyad’s frame.
Solve the Resonance Puzzle:
- Align the resonance nodes to match the pattern from the “Bonds of Fire” mission (refer to your quest log).
- This grants the One For All perk: Landing rapid precision hits grants a stacking damage buff for you and nearby allies (up to 35%).
- Hidden Benefit: The catalyst also boosts the Barrow-Dyad’s stability by 20, making it laser-accurate.
Optimizing the One For All Catalyst
Now that the catalyst is unlocked maximize its effectiveness with these tips:
Synergize With Subclasses:
- Void Hunters: Use Invisibility to land precision shots safely.
- Solar Titans: Pair with Sunspots for added ability uptime.
- Strand Warlocks: Threadlings distract enemies while you stack buffs.
Mod Loadouts:
- Helmet: Pulse Rifle Targeting
- Arms: Reload Speed or Pulse Rifle Dexterity
- Chest: Pulse Rifle Reserves
- Legs: Pulse Rifle Scavenger
- Class Item: Reaper (generates Orbs on class ability use)
Fireteam Play: Stick with allies to maintain the damage buff. Ideal for Raids like King’s Fall or Root of Nightmares.
Why the One For All Catalyst Matters in the Meta
The Heresy meta emphasizes team synergy and burst damage, making the Barrow-Dyad a top-tier choice for:
- Grandmaster Nightfalls: Melt Champions and Overloads with stacked buffs.
- Raids: Boost team DPS during boss phases (e.g., Warpriest in King’s Fall).
- PvP (Limited Use): While less dominant here, the buff can clutch Trials of Osiris rounds.
Lore Behind the Barrow-Dyad
The Barrow-Dyad is tied to the ancient “Pact of the Concordat,” a forgotten alliance between Golden Age humans and a rogue Hive sect. The One For All Catalyst symbolizes this unity, channeling collective strength into devastating firepower. Ghost fragments found in the Cosmodrome bunker hint at a betrayal that doomed the pact—a cautionary tale for Guardians seeking power through unlikely alliances.
Conclusion
Unlocking the One For All Catalyst for the Barrow-Dyad is a grind, but the payoff is immense. This guide ensures you’ll navigate the quest efficiently, avoid pitfalls, and leverage the catalyst’s full potential. Whether you’re battling Lucent Hive or facing down raid bosses, the Barrow-Dyad’s enhanced synergy will make you an invaluable asset to any fireteam. Now gear up, Guardian; the stars await your legend.
