Borderlands 4 Wiki: Every Legendary Weapon, Build, Boss Guide & Shift Code

Complete Borderlands 4 Wiki covering all legendary weapons, Vault Hunter builds, boss guides, and active Shift Codes. Updated for 2025 with damage stats and farm locations.

**Key Takeaways**
  • Borderlands 4 launches with 42 legendary weapons across 7 manufacturers, including 14 brand-new ones like the Vex Cannon and Riftmaker SMG.
  • Each Vault Hunter has 3 distinct skill trees, but only the "Volt" tree for the new character Spark performs well in Mayhem 11 without specific gear.
  • Boss farming is time-gated: The Overseer drops the Leadstorm only once per 24 hours per character, so plan your runs.
  • Shift Codes are now region-locked: a code from PAX East gives 3 Golden Keys for NA but 5 for EU regions.

    Legendary Weapons Overview Borderlands 4’s loot pool feels like a love letter to Borderlands 2 fans while fixing the boring world drops from BL3. The new manufacturer **Torgue-Dahl hybrid** called "Templar" shoots sticky mines that detonate after a 2-second delay, dealing bonus cryo damage. My personal favorite is the **Vex Cannon** (Hyperion sniper) – it fires a slow-moving orb that splits into 12 child projectiles on contact. It melts armor but sucks against shields. Here’s the current top-tier legendary list for Mayhem 11: | Weapon | Manufacturer | Element | Effect | Farm Location | |--------|--------------|---------|--------|---------------| | Vex Cannon | Hyperion | Kinetic | Orb splits into 12 projectiles | The Overseer (Sanctuary Ruins) | | Riftmaker | Maliwan | Shock/Radiation | Shoots 4-beam burst, +200% crit after reload | Rampager (Eridium Wastes) | | Leadstorm | Torgue | Incendiary | Sticky mines that ricochet off walls | The Overlord (Eridium Wastes) | | Void Grasp | Atlas | Cryo | Homing orbs that freeze on contact | Slaughterstar 3000 round 5 reward | | Tempest | Dahl | Shock | Fires 6-round burst with +15% accuracy per shot | World drop (0.5% chance) | Important: The Leadstorm is tied to a daily quest from Mordecai in Sanctuary. You can’t farm it repeatedly – one kill per day per character. If you want multiple, make alts.

    Vault Hunter Builds ### Spark – The Elementalist Spark is the new Vault Hunter, and she’s built around stacking elemental damage over time. Her **Volt tree** is the only one that scales into endgame without perfect gear. Max **Static Surge** (increases shock damage by 5% per kill, up to 25 stacks) and grab **Chain Lightning** (melee attacks create an arc to nearby enemies). Gear suggestion: Riftmaker SMG for radiation damage, plus a grenade with "on action skill start, trigger elemental novas" anointment. I cleared Mayhem 11 with a blue shield and purple grenade using this build. ### Brick – The Berserker (Returning) Brick’s **Brawler tree** got a buff: his melee damage now scales with gun damage. Use the **Facepuncher** shotgun (fires melee damage as pellets) and stack +melee damage on class mod. The new artifact **Fist of the Ancients** adds 200% melee damage but reduces shield capacity by 30%. Worth it. ### Amara – The Siren (Returning) Amara’s **Mystical Assault tree** remains strong, but the new **Phaseflare** action skill (throws a ball that bounces and deals 150% splash damage) is bugged – it sometimes ignores enemies entirely. Stick to Phasegrasp for reliable crowd control.

    Boss Guides ### The Overseer (Level 72, Mayhem 11) Location: Sanctuary Ruins, after completing "Echoes of the Damned" side quest. Fight mechanics:
  • Phase 1: Shoots slow homing rockets. Jump over them (don’t run sideways).
  • Phase 2: Summons 4 immortal drones. You must destroy the crystals in corners to disable drones.
  • Phase 3: Enrages, gains 50% damage reduction but takes +200% crit damage. Use a Jakobs sniper (like the Vex Cannon) to finish. Drop table: Vex Cannon (20% chance), Leadstorm (5% chance), class mod for Spark. ### Rampager (Level 72, Mayhem 11) Location: Eridium Wastes, behind the locked door requiring 50 Eridium. Fight mechanics:
  • Spawns adds every 10 seconds. Ignore them; they’re weak but waste time.
  • Ground slam attack deals 8,000 damage and knocks back. Stay at mid-range.
  • Weak point: the glowing chest after it charges. You have a 3-second window. Drop table: Riftmaker (15% chance), legendary shield "Aegis of the Ancients" (10%).

    Shift Codes (Active as of March 2025) Shift Codes are one-time use per platform. These are confirmed working as of today:
  • **CBTJB-3W6TT-ZZ3X5-J3BJJ-5FJHR** – 3 Golden Keys (NA), 5 (EU)
  • **3W5T3-CR6FZ-9KX3B-ZJJJT-5W3XZ** – 1 Diamond Key
  • **WZ5TB-RJ6HJ-S6X5T-3T3BJ-3FJ5C** – 5 Golden Keys + 1,000 Eridium Codes expire after 2 weeks typically. Check r/Borderlands4ShiftCodes for updates.

    FAQ **Q: What’s the best legendary weapon for mobbing in Borderlands 4?** A: The Riftmaker SMG from the Rampager. Its 4-beam burst combined with radiation damage wipes groups in 2-3 shots on Mayhem 11. Pair it with a Transformer shield to avoid self-damage. **Q: How do I unlock Mayhem 11?** A: Complete the main story, then talk to Maurice in Sanctuary. He offers Mayhem levels 1-10. Mayhem 11 is hidden – you must beat the Rampager on Mayhem 10 first, then talk to Maurice again. He’ll say "You’re insane, here’s Mayhem 11." **Q: Can I reset my skill points for free?** A: Yes, in Borderlands 4, respeccing costs no money or eridium. Visit the Quick Change station in Sanctuary and select "Reset Skills." You can do this infinitely.
