Jabbermogwai - Borderlands 3 Farming Guides
Location: Voracious Canopy on Eden 6
Part of: Crew Challenge
Drops: Magnificent (Vladof Pistol) and Hellfire (Dahl SMG)
Jabbermogwai is found in Voracious Canopy, a zone on Eden 6. You'll find this enemy to the north of where the fast travel terminal is, on the opposite end of the zone as the crashed space ship with GenIVIV in the wide open area just outside the Jabber city. If you plan on farming this Crew Challenge be sure to grab the terminal where you see me standing on the map in the screenshot above. This is the closest terminal to the mob.
As far as loot goes, Magnificent (Vladof Pistol) and Hellfire (Dahl SMG) are both on the Jabbermogwai's dedicated drop list. For the Hellfire SMG to drop from this enemy you'll need to kill it with Incendiary damage. If you do that you'll have a much better chance of seeing Hellfire drop.
