Is your Light bright enough to stand in full gaze of the Hive’s abyss?

Arise for Crota, Son of Oryx, the Hope-Eater! He who has seized the Sky lair above Ceres, which peers into other planes, now vassal to the might of the Worldbreaker! Within these keyholes our brood communes with unheard voices. They who whisper that the curse of our Thralls is a blessing granted by the Deep. Now, in honor of the God-Knight, we fashion these gluttonous whispers into death. His Hellmouth becomes home to the profane: the corpse of the Sky, reborn in the abyss.
— Enkaar, the Anointed

Necrochasm Exotic Catalyst Steps

To acquire the Exotic Catalyst for the Necrochasm, complete both timed trials in Crota’s End raid, and ensure that one player has the Necrochasm equipped while standing on a plate. Players without the Necrochasm won’t receive the Catalyst.

Timed Trial #1

Time limit: 1 minute, 30 seconds

  • Find and activate the glowing plate located after the Bridge encounter. Once activate it will say “Crota’s Minions appear”.
    • Plate location: When looking at the stairs that go to the next encounter, go to the far upper right, you should see a glowy plate.
    • Make sure at least one fireteam member has the Necrochasm equipped when activating the plate, or it will not work.
  • Take out all Swordbearers and many enemies (swords can be dropped and picked back up). If you beat all the enemies in time, you’ll see a message saying “Crota’s minions are defeated.”

Time Trial #2

Time limit: 1 minute, 30 seconds

  • Find and activate the second glowing plate, located after completing the Ir Yut, Deathsinger encounter.
    • This plate is located in the room on the bottom right, below where Hive Boomer Knights spawn.
  • Repeat the process of defeating all enemies within the time allowed.
    • Heads up: This Timed Trial is much tougher. There are three Swordbearers (left, right, middle) and a significant amount of powerful Wizards and Gatekeepers.
  • Once you see the message saying “Crota’s minions are defeated” the Catalyst for Necrochasm will drop.

How to Unlock the Exotic Catalyst

  • Collect 20 Essence of the Oversoul (this is earned by completing encounters in Crota’s End raid).
