Exotic Catalyst IV

Overview

Exotic Catalyst IV is a Triumph worth 5 points. It is earned by finishing the quest "Should You Choose to Accept It, Part IV", which unlocks the fourth Exotic Catalyst for Revision Zero, an Exotic Pulse Rifle from Season of the Seraph. This catalyst is the 4-Timer Refit.

How to complete

1. Finish Parts I to III first. Part IV starts after step 53 of More Than a Weapon.
2. Get the cryptographic index from an Annex (Archimedes or Diocles), then travel to the Cosmodrome for instructions.
3. Decrypt the passcode cipher (SHASKI) by clearing patrols and enemies there, then upload it at the dead drop in the Exodus Garden 2A Lost Sector.
4. Run Operation: Seraph's Shield on Legend difficulty and find the weapon schematic it contains.
5. Complete the operation to receive the 4-Timer Refit. Part IV adds one final step, a visit to a weapons expert to analyze the catalysts, before the triumph completes.

Catalyst

The 4-Timer Refit gives Revision Zero the Fourth Time's the Charm perk: rapid precision hits return two rounds to the magazine.

Notes

These quest steps are from the Season of the Seraph launch (December 2022 to January 2023). Later seasons may have changed them.
