How to complete the quest for the Exotic Catalyst from revision 7.2.2 in Destiny 2

Each season in Destiny 2 unlocks access to an iconic exotic. For the Season of the Lost it's the Lorentz Driver Fusion Rifle. You will also have access to the Exotic Weapon Catalyst, but there are several steps you will need to get it through a mission called Review 7.2.2. You can acquire this mission by speaking to the traveler's gunsmith, Banshee-44.

How to complete the review 7.2.2

Step 1

You will need to collect field data for the Lorentz Pilot Catalyst by fighting against challenging fighters, Guardians and high-value champions or targets. Your best bet to complete this fast enough is to take part in the Vanguard, Gambit, or Crucible activities for each one. Of the three choices, we recommend Crucible for taking out the Guardians and playing Vanguard Strikes for the toughest opponents.

• Defeated Challengers Fighters: 50
• Defeated Guardians: 50
• Defeated champions or high-value objectives: 15
