Necrochasm is the Crota's End exotic auto rifle, and on its own it is only part of the gun. The Catalyst — earned by killing Crota with Necrochasm equipped — is what turns Cursed Thrall explosions into the weapon's whole identity, and the Masterwork is what finishes it. This bundle is all three in one order.
What is in the bundle
| Part | What it takes |
|---|---|
| Necrochasm | Craftable from Crota's End red-border drops. We farm the patterns and shape the weapon. |
| Catalyst | A Crota kill with Necrochasm equipped, so it cannot be done before the weapon exists — this is why it is a bundle rather than two purchases. |
| Masterwork | The catalyst kill-tracker completed and the weapon fully upgraded. |
Why the bundle rather than the parts
Because the ordering is fixed. The Catalyst cannot start until the weapon is in your hands and the Masterwork cannot start until the Catalyst drops, so buying the three separately means three queues instead of one run of the raid.
If all you want is the weapon and the Catalyst drop, without finishing the Masterwork, that is a smaller order we sell on its own — this page is the version that completes the catalyst and fully upgrades the gun.
What it has cost
143 confirmed orders. About half of those were bespoke builds quoted in chat, so the cleanest read is the standard bundle: over the last two years it has ranged $63 to $108 depending on how much of Crota's End you had already cleared, and its four most recent orders — July 2025 through June 2026 — all went through at $95.
