The most efficient method to get Lucian’s Flank is to farm the Saddleback boss at the Old Scrape Drill Site. This particular site is located in the southern end of Cuspid Climb, near the border of Terminus Range and Fadefields. Saddleback appears alongside the Immortal Boneface boss, and they make up the Meathead Riders boss duo.

After arriving at the Old Scrape Drill Site, defeat the initial wave of enemies, and the Meathead Riders will emerge simultaneously. Saddleback has a small chance of dropping Lucian’s Flank upon defeat. If he doesn’t, use Moxxi’s Big Encore station located at the drill site’s entrance to repeat the boss fight. The station accepts cash or Eridium for each repetition, and you can sell the unwanted loot from each one to avoid losing money.
