How to Unlock the Legendary Lucian's Flank Assault Rifle

Lucian's Flank is an impressively-fast Assault Rifle, making it useful for builds that can take advantage of its high Fire Rate. Its unique effect also allows it to refill its own Ammo whenever you Crit.

However, do note that it has an internal Cooldown, meaning it can't continuously fire non-stop. Regardless, it's still a great option for its speed and capacity.

Unlock Location:

• Progress through the Terminus Range region, heading south where it borders the Fadefields.
• Unlock the Old Scrape Drill Site, where Saddleback resides as the boss.

Farm Method:

• Defeat Saddleback, who can drop Lucian's Flank in addition to War Paint.
• Use the Encore Machine to reset the fight.
• Repeat farming runs for Lucian's Flank.
