Billy The Anointed - Borderlands 3 Farming Guides
Location: Eden-6, Jakob's Estate
Part of: Lair of the Harpy Story Quest
Drops: Gatling Gun, Lead Sprinkler (Jakobs AR) and Raging Bear Moze Class Mod
Billy The Anointed is found in Jakob's Estate on Eden-6. He's located in the theater, the same location where you solved the stage puzzle earlier in the game. You know, the one where you had to match what is on the stage with the picture on the ground. Thankfully we don't have to do any of that nonsense this time. Billy will be spawned in the room when we arrive and all you have to do is take him out then smash his body to bits when it turns to crystal.
As far as loot goes, he has an increased chance to drop Gatling Gun and Lead Sprinkler (Jakobs AR) along with the Raging Bear which is a Moze class mod. The Moze class mod is a unique drop which only comes from this boss, everything else can be found as a world drop as well.
