What Is Lucian’s Flank?

• Type: Legendary Assault Rifle (Vladof)

• Effect (“Trample”): Critical hits have a chance to refill up to 2 ammo in the magazine (on internal cooldown)

• Usage: Best for high fire-rate, crit-focused builds, since it gives sustain in long fights

Where to Farm Lucian’s Flank

1. Go to The Old Scrape (Ripper Drill Site)
   In the Terminus Range region, locate the Old Scrape Ripper Drill Site—this is the area housing the boss Saddleback.

2. Defeat Saddleback (Meathead Riders)
   Lucian’s Flank is a chance drop from Saddleback, who fights alongside Immortal Boneface.
   You may need to reset or re-trigger the boss engagement repeatedly to farm the drop.

3. Use Encore Machine (if available)
   Some maps or boss arenas may include a device (Encore Machine) to replay the boss fight. Use it to redo the fight without leaving the area.

Tips to Improve Your Odds

• Speed & efficiency matter: Build your loadout to clear the boss fight fast.

• Loot bonuses: Use gear or skills that boost legendary or rare drop rates.

• Farm in groups: More players = more loot rolls → higher chance someone gets the drop.

• Be consistent: Since the drop is RNG, repeated attempts are expected.

Builds & Synergies

• Crit-based builds: Because of “Trample,” builds with high critical damage or crit rate get the most out of Lucian’s Flank.

• Sustained combat: Use it in scenarios where ammo sustain matters (long fights, boss runs).

• Balance damage and utility: Don’t neglect elemental weapons or utility gear in favor of just chasing this rifle.

Should You Go After Lucian’s Flank?

Yes — especially if your build leans into crits and sustained DPS. While the drop is rare, this weapon can significantly improve ammo sustain for aggressive, high-output builds. But don’t abandon farming other strong legendaries if Lucian’s Flank takes time.

Skip the Grind (Optionally)
