PC / Global, base game and released DLC
WHERE & HOW TO FARM

Where to farm

Research and Development, along the route through the map.

For players hunting a Celestial Vanquisher class mod, include EX Stalker in a Research and Development clear and inspect the drop after the fight. This is a focused check inside a map that also has chests, lockers, and other named enemies. The class mod is not guaranteed, so make each visit useful by gathering other relevant loot while passing through.

GET STARTED

How to farm

Before you go

  • Reach Research and Development through the story.
  • Bring a character build that can handle the enemies on the route.
  • Leave inventory room for class mods and other drops.
  1. Enter Research and Development and follow the main route into the area.
  2. Search ahead for EX Stalker as you clear the surrounding enemies.
  3. Defeat EX Stalker and inspect the drops for a Celestial Vanquisher class mod.
  4. Check whether the mod matches your character and improves the skills or stats you need.
  5. Collect useful loot from nearby chests and lockers while continuing through the map.
  6. Exit the area and save and quit to reset the encounter.
  7. Reload and return to Research and Development for another EX Stalker check if needed.

Farming tips

  • A class mod only helps if it suits your character and build; compare its bonuses before keeping it.
  • Combine the target check with the map’s other loot opportunities so a non-target drop still has value.

Repeat, collect and use

Repeatable by resetting the map and returning. EX Stalker’s class mod drop is a chance, not a guaranteed reward.

Common mistakes

  • Assuming any class mod is a Celestial Vanquisher can waste the run; read the item name and stats.
  • Rushing out immediately after the fight can miss nearby containers; collect useful route loot before resetting.
  • Continuing indefinitely after a useful mod drops may have low value; reassess your build and goals.

When to stop or switch

Stop once you have a class mod that supports your character, or switch to another goal if the available drops do not improve your setup.
