Borderlands 4 Wiki: Legendaries, Builds, Bosses & Shift Codes

Borderlands 4 Legendary Weapons: What’s New and What’s Back Borderlands 4 launches with over 30 legendary weapons, and I’ve spent about 80 hours testing most of them. The standout this time is the new anointment system—each legendary now has a special effect slot that can be rerolled using Eridium. That alone makes farming more forgiving than in Borderlands 3. ### Returning Favorites

**Unkempt Harold** – The classic Torgue pistol returns with a fixed +50% splash damage anointment. It drops from the mini-boss "Harold the Unhinged" in the Dustlands.

**Lyuda** – Zer0’s sniper rifle is back with a new scope variant that increases critical hit damage by 30%. Farm from the rare spawn "Lyudmila" in the Frozen Tundra.

**Conference Call** – Shotgun still fires projectiles in a spread pattern. Now has a chance to ricochet off enemies for 25% extra damage. ### New Legendaries Worth Farming

**Void Cannon** – A Maliwan heavy weapon that fires a slow-moving orb that pulls enemies in before detonating. Drops from the raid boss "The Maw."

**Laser Sploder** – Tediore SMG that, when reloaded, throws a turret that fires tracking lasers. Excellent for mobbing.

**Time Slicer** – Vladof sniper rifle with a unique ability: landing a critical hit slows the enemy by 50% for 3 seconds. Great for boss fights. ### Legendary Drop Rates Based on community data from the first two weeks:

Bosses: ~10-15% drop rate for a legendary item

Badass enemies: ~3-5%

Chests: ~1-2%

Dedicated drops (specific bosses): 20-25% ---

Vault Hunter Builds: Best Starter and Endgame Options Borderlands 4 features four Vault Hunters: Amara, Moze, FL4K, and Zane. Each has three skill trees. Here’s what’s working early on. ### Amara – Elementalist Build (Best for Beginners)

**Skill Tree:** Mystical Assault (right tree) – focuses on elemental damage and splash.

**Key Skills:** "Searing Wrath" (increases fire damage by 20%), "Conflux" (chance to apply a second element on hit).

**Weapons:** Any high-fire-rate elemental SMG or pistol. The "Laser Sploder" is perfect.

**Shield:** Transformer (absorbs shock damage).

**Why it works:** You can melt groups without aiming perfectly. Great for story mode. ### Moze – Iron Bear Demolition (Endgame Viable)

**Skill Tree:** Bottomless Mags (left tree) + Demolition Woman (middle tree).

**Key Skills:** "Stoke the Embers" (increases incendiary damage by 25%), "Vampyr" (heal 5% max health on grenade damage).

**Weapons:** Any high-magazine AR (e.g., "Shredifier" legendary).

**Grenade:** Cloning Maddening Tracker (splits into 6 child grenades).

**Why it works:** Moze can spam grenades and never reload. Endgame Mayhem 10 viable. ### FL4K – Crit Build (Sniper/Damage Dealer)

**Skill Tree:** Hunter (left tree) – boosts critical hit damage and pet damage.

**Key Skills:** "Furious Attack" (gain 2% gun damage per kill, stacks up to 25), "The Power Inside" (enemies below 50% health take 30% more damage).

**Weapons:** Lyuda or any high-crit sniper.

**Why it works:** One-shots trash mobs and melts bosses if you can hit crits consistently. ### Zane – Barrier/Drone Support (Co-op Focus)

**Skill Tree:** Doubled Agent (middle tree) – allows two action skills.

**Key Skills:** "Synchronicity" (action skills active increase gun damage by 15% each), "Good Misfortune" (kill skill: reduce action skill cooldown by 20%).

**Weapons:** Conference Call or any fire-rate SMG.

**Why it works:** Constant uptime on Barrier (makes you immune to projectiles) and drone for healing. Best for co-op. ---

Boss Guides: Strategies for the Toughest Fights Here are three early-to-mid game bosses that give players trouble. ### The Gravewarden (Story Boss, Level 15)

**Location:** The Crypt, Dustlands.

**Recommended Gear Score:** 450+ (Normal), 600+ (True Vault Hunter Mode).

**Mechanics:** He slams the ground (knockback), fires homing skulls, and summons skeletons at 50% health.

**Strategy:** Stay at mid-range. Shoot the glowing chest weak spot. When he slams, jump to avoid the shockwave. Kill skeletons quickly to avoid being overwhelmed.

**Loot:** Guaranteed legendary class mod for your Vault Hunter. ### The Maw (Raid Boss, Level 35)

**Location:** The Abyss, Endgame.

**Recommended Gear Score:** 900+ (Mayhem 1).

**Mechanics:** Three phases: Phase 1 – punches and tail swipes; Phase 2 – spawns minions and fires lasers; Phase 3 – enrages, doubles attack speed.

**Strategy:** Use a corrosive weapon for Phase 1, shock for Phase 2, and fire for Phase 3. Bring a Transformer shield (absorbs shock). Moze with Iron Bear can tank Phase 2 lasers.

**Loot:** Void Cannon (legendary heavy), The Maw’s Eye (legendary shield). ### The Unstoppable (Optional Boss, Level 20)

**Location:** Highway 66, The Highlands.

**Recommended Gear Score:** 600+.

**Mechanics:** He’s a giant loader with a rocket launcher arm. He’s slow but hits hard. He will repair himself if not damaged fast enough.

**Strategy:** Use shock damage to deplete his shield, then corrosive to eat through armor. Stay mobile—his rockets track slightly. FL4K’s crit build can kill him in under 30 seconds with a Lyuda.

**Loot:** The Unstoppable’s Legs (legendary artifact – increases movement speed by 15%). ---

FAQ **Q: What is the best legendary weapon for early game in Borderlands 4?** A: The "Unkempt Harold" is my pick—it drops from a level 10 mini-boss in Dustlands and melts everything up to level 20. You can farm it in under 5 minutes per run. **Q: How do I unlock Mayhem mode in Borderlands 4?** A: After completing the main story, talk to Marcus in Sanctuary. He gives the mission "Mayhem Rising." Complete it to unlock Mayhem 1-10. Each level increases enemy health and damage but boosts loot quality and cash. **Q: Can I respec my Vault Hunter without paying?** A: Yes. In Borderlands 4, respeccing costs Eridium (50 per respec). But you can also find "Respec Tokens" as random drops from Badass enemies—they’re rare but free. I’ve found about 10 in 80 hours of play.
