Demoskaggons - Borderlands 3 Farming Guides
Location: The Droughts on Pandora
Part of: Rare Spawn
Drops: Night Hawkin (Dahl SMG) and Monocle (Jakobs Sniper)
Demoskaggons are found in The Droughts on Pandora, around the same area you fight Dumptruck for the Buttplug gun. Right after going over the jump with your vehicle (heading towards the Demoskaggons) you'll find a save terminal which you'll want to grab if you plan to farm these enemies. This is the closest terminal to this spot and you'll enter here after every game reset.
Keep in mind that the Demoskaggons are not a "Crew Challenge/Target of Opportunity" which means they may not show up every time you venture to this location. If you come here and you fight nothing but regular Skags then exit/re-enter the game and try again.
As far as the loot goes, the Demoskaggons drop Night Hawkin (Dahl SMG) and a Monocle (Jakobs Sniper).
