Quick answer: To get Necrochasm in Destiny 2, beat the Crota's End raid, then grab the free "Bottomless Pit" quest from Crota's discarded sword in the boss room. Kill 100 Hive with the Husk of the Pit (it upgrades into the Eidolon Ally), then collect 20 Essence of the Oversoul from raid encounters and Triumphs to claim the gun. The catalyst needs 35 Essence total (your first 20 count, so 15 more). It's a 720 RPM Kinetic auto rifle whose Cursebringer perk makes precision kills detonate Cursed Thrall.
Necrochasm is one of the most iconic Exotics in the Destiny franchise — the Hive auto rifle that "blooms" enemies into explosions — and it's locked behind Crota's End, the returning raid that's still a weekly farm in Year 8 (Renegades). With Bungie's Monument of Triumph update (live since June 9, 2026) marking the final major content drop and old raids rotating through the new Pantheon boss-rush, plenty of Guardians are circling back to finish the Necrochasm grind before they move on. This guide covers the exact quest steps, the fastest way to farm Essence of the Oversoul, the full catalyst path, and whether the gun is actually worth your time in the current sandbox.
What Is Necrochasm and Is It Worth Getting?
Necrochasm is a 720 RPM Rapid-Fire Frame Exotic auto rifle with no elemental affinity — it sits in the Kinetic slot. Its identity comes entirely from its intrinsic perk, Cursebringer:
"Precision final blows with this weapon trigger a Cursed Thrall explosion. Final blows with Cursed Thrall explosions refill the magazine."
In practice that means precision kills spawn a chain-reaction blast, and if that blast finishes another target your magazine instantly refills — so in a dense room of red-bars you can rarely stop firing. It's a premier ad-clear / fun build weapon, not a boss-DPS option. Rapid-Fire Frames also get bottomless mags and bonus reload on empty, which stacks beautifully with Cursebringer's refill loop.
The catalyst transforms it from "fun" to "genuinely strong." The reworked catalyst grants One For Thrall (OFT) — an upgraded One For All that gives +35% weapon damage plus a boost to Range, Handling, and Aim Assist for 10 seconds, and crucially the timer refreshes on every kill. With OFT live you can hold near-permanent uptime while clearing trash, making catalyst-Necrochasm one of the best add-clear primaries in the game.
Verdict: If you enjoy Hive-themed chaos and want a top-tier PvE add-clear primary, Necrochasm + catalyst is absolutely worth it. If you only chase meta DPS, skip it — but you'll be missing one of the most satisfying weapons in Destiny 2.
What You Need Before You Start
There are no quest prerequisites beyond access to the raid itself:
- Crota's End raid unlocked (it's a free, permanently available raid — no expansion purchase required).
- A fireteam (or a confident solo/LFG plan) able to reach and defeat Crota in the final encounter.
- Patience for the Essence grind — the gun is fast, but the catalyst is a multi-week farm for most players.
That last point is the real wall. Reaching Crota is easy; stacking enough Essence of the Oversoul for the catalyst is where people stall. If clearing Crota's End reliably is the blocker — or you just want the catalyst farmed efficiently — a Crota's End raid carry removes the bottleneck entirely (more on that below).
How to Start the Bottomless Pit Quest
The Necrochasm quest is called "Bottomless Pit," and it does not drop randomly. Here's exactly how to begin:
- Complete the Crota's End raid through to the final boss.
- Defeat Crota in the last encounter.
- After Crota falls, walk to Crota's discarded sword (the relic) in the boss arena and interact with the vendor prompt.
- Accept "Bottomless Pit" — it's free and guaranteed to appear (no Spoils of Conquest or currency required).
You only have to do this once per account. From there it's a two-step weapon quest.
Necrochasm Quest Steps (Full Walkthrough)
Step 1 — Husk of the Pit: Get 100 Hive Kills
Accepting the quest hands you the Husk of the Pit, a basic auto rifle. Your job: defeat 100 Hive with it.
- Hive killed inside Crota's End count for more progress per kill.
- The Altars of Sorrow activity on the Moon is the classic farm spot — endless Hive, fast respawns, and it counts.
- Once you hit the threshold, the Husk of the Pit transforms into the Eidolon Ally, a Legendary auto rifle (rolling Perpetual Motion + Rangefinder). Equip the Eidolon Ally to continue — this is the weapon that completes the next step.
Step 2 — Collect 20 Essence of the Oversoul
The final step for the gun itself requires 20 Essence of the Oversoul. You earn Essence from:
- Weekly Crota's End completions — each weekly full clear is a guaranteed Essence source.
- Raid encounters — there's a small chance for Essence to drop per encounter on top of the weekly guarantee.
- Crota's End Triumphs and challenges — completing these awards Essence in chunks and is the fastest way to front-load your total.
Once you bank 20 Essence, the quest completes and Necrochasm is yours. For most players the gun takes one to two raid weeks; if you've been knocking out Triumphs along the way, you can finish it much faster.
How to Get the Necrochasm Catalyst (One For Thrall)
The catalyst is the real grind, and it uses the same Essence of the Oversoul currency.
- The catalyst unlocks at 35 Essence of the Oversoul total.
- The count is retroactive: the 20 Essence you already spent on the gun still count, so you only need 15 more after claiming Necrochasm.
- Triumphs and challenges are your friend — they hand out Essence in larger amounts than passive encounter drops, so a player chasing the catalyst should prioritize unfinished raid Triumphs over blind farming.
Be realistic about the time: because guaranteed Essence is largely weekly-gated, plus a small per-encounter chance, players have reported double-digit full clears plus repeated Crota/Ir Yut kills to top off the catalyst once the easy Triumphs are gone. There's no daily-spammable shortcut — this is a patient, week-over-week raid farm.
Once you hit 35 Essence, equip the catalyst, then masterwork it through normal weapon kills to activate One For Thrall and unlock Necrochasm's best version.
Fastest Way to Farm Essence of the Oversoul
Putting the efficient path in one place:
- Clear all unclaimed Crota's End Triumphs/challenges first — biggest Essence per run, and you'd want them done anyway.
- Run the full raid weekly for the guaranteed Essence — don't skip your weekly clear.
- Farm encounters (Crota / Ir Yut) for the small per-encounter chance once Triumphs are exhausted.
- Stack it with a fireteam — more clears per week = more guaranteed Essence; consistent, fast clears compound the farm.
If you can't field a reliable team, this is exactly the kind of weekly raid grind where a carry pays for itself — you get the clears, the Triumphs, and the Essence without spending weeks chasing a fireteam.

How Necrochasm Plays in the Current Sandbox
In Year 8 (Renegades / Season: Lawless), primary add-clear weapons that generate their own ammo loop are valuable for sustained content — and that's Necrochasm's whole game. With the catalyst's One For Thrall active, you get +35% damage on tap while you chain Cursed Thrall explosions through trash mobs, making it a strong pick for Nightfalls, seasonal activities, lost sectors, and the Pantheon ad-density encounters. Pair it with an Arc or Solar build that rewards rapid kills and it becomes a self-sustaining cleanup machine.

Common Mistakes That Slow the Necrochasm Grind
A few avoidable errors cost Guardians weeks on this quest:
- Skipping Triumphs early. Triumphs and challenges are the single biggest Essence source. Players who blind-farm encounters before clearing their Triumphs end up grinding far longer than they need to — do the Triumphs while you're already in the raid.
- Not equipping the Eidolon Ally for Step 2. After 100 Hive kills the Husk of the Pit becomes the Eidolon Ally; keep it equipped so the next step tracks. Some players swap it off and wonder why nothing progresses.
- Stopping at 20 Essence. If you want the catalyst, keep banking Essence — you only need 15 more after the gun, and the count is retroactive, so there's no reason to start over later.
- Treating it like a daily grind. Most guaranteed Essence is weekly-gated, so the realistic plan is a full clear (plus Triumphs) every reset until you hit 35. Plan around resets, not single sessions.
Knock those out and Necrochasm + catalyst is a clean, well-defined raid project rather than an open-ended slog.
FAQ
How do you get Necrochasm in Destiny 2? Beat the Crota's End raid, accept the free "Bottomless Pit" quest from Crota's discarded sword in the boss room, kill 100 Hive with the Husk of the Pit (it becomes the Eidolon Ally), then collect 20 Essence of the Oversoul from raid encounters and Triumphs to claim the weapon.
How much Essence of the Oversoul do you need for Necrochasm and its catalyst? The gun needs 20 Essence of the Oversoul. The catalyst needs 35 Essence total, but it's retroactive — your first 20 count, so you only need 15 more after getting the weapon.
What is the fastest way to farm Essence of the Oversoul? Knock out unclaimed Crota's End Triumphs and challenges first (they award the most Essence), run the full raid weekly for the guaranteed drops, and farm encounters for the small per-encounter chance. Most guaranteed Essence is weekly-gated, so there's no daily spam method.
Is the Necrochasm catalyst worth it? Yes — the catalyst grants One For Thrall: +35% weapon damage plus Range, Handling, and Aim Assist for 10 seconds, refreshing on every kill. It turns Necrochasm into one of the best add-clear primaries for PvE.
Is Necrochasm still obtainable in 2026? Yes. Crota's End is a free, permanently available raid, so the Bottomless Pit quest and Necrochasm remain obtainable in Year 8 (Renegades), even with Destiny 2 in its Monument of Triumph final-update phase.
Is Necrochasm good for PvP? It's primarily a PvE add-clear weapon — Cursebringer rewards killing chains of weak enemies. It can function in PvP as a 720 RPM auto rifle, but it's not a meta Crucible pick; build for PvE.
