How to farm Lucian’s Flank legendary Assault Rifle in Borderlands 4

- Travel to the Cuspid Climb area located on the right of the Terminus Range.
- Navigate to the Southern boundary of the region and go towards the right edge of Cuspid Climb from Checkpoint Vermillion POI.
- You will be able to find a Ripper Drill Site called The Old Scrape here. This region has two boss monsters that you can defeat.

- Enter the Drill Site and defeat all enemies that block your way. Once you get to the enclosed rocky area, you will have to take down some waves of mobs emerging from the caves and makeshift houses.
- After some time, the bosses, The Immortal Boneface and Saddleback will come out into the arena and enter the fight. Defeat both of them to clear the arena.
- During the beginning of the boss fight, you should target Saddleback first and simply spam as many critical hits as possible.

- After taking down Saddleback, you can concentrate your abilities and complete firepower on Boneface. It is recommended to carry elemental damage weapons in your loadout, preferably legendary grade, when fighting this duo.
- You can use Moxxi’s Big Encore to challenge the boss fight again to farm for the preferred items. Since Lucian’s Flank legendary Assault Rifle in Borderlands 4 has a chance of dropping from this fight, you may need to grind for a few rounds before you obtain the gun.
