Best Legendary SMGs Ranked in Borderlands 4
These SMGs excel in distinct roles: Kaoson for raw sticky DPS and Atlas synergy, Darkbeast for piercing burst and corrosive applications, Hellfire for sustained incendiary damage, and Plasma Coil for fast shock/radiation status application. Each weapon’s strengths depend on build, element, and desired combat range.
Kaoson: Sticky Gyrojets and DPS Potential
Kaoson fires Torgue Sticky Gyrojets that attach to targets and explode after a short delay, enabling stacked damage against single targets and groups. It always comes with Atlas Trackers, which synergize well with Atlas Firmware and skills that amplify explosive or applied effects.
Best rolls prioritize the 4% Sticky Bonus and high fire rate to maximize the number of gyrojets attached before detonation. Players benefit from pairing Kaoson with magazine or reload mods that increase uptime between bursts.
Use Kaoson for boss fights and sustained DPS windows. It performs poorly at extreme range but dominates close-to-mid engagements where gyrojets reliably stick and detonate.
Darkbeast: Piercing Bullets and Corrosive Damage
Darkbeast shoots piercing bullets with a native Corrosive element, making it ideal against armored and high-armor targets. Its projectiles have a 20% chance to cause an explosion on hit, amplifying single-shot damage and applying Corrosive status quickly.
Optimal builds lean into accuracy and critical damage to make each piercing shot count, and a Maliwan-licensed underbarrel adds secondary elemental effects for hybrid damage types. Farming Darkbeast from Voraxis yields the best chance to obtain strong elemental rolls.
Darkbeast suits players who want precise, high-damage engagements and need to strip armor fast while keeping mobility between shots.
Hellfire: Elemental Burn and High DPS
Hellfire returns as a Legendary Ripper SMG focused on Incendiary/Explosive output in Borderlands 4, firing Torgue explosive rounds with high incendiary damage. It benefits characters that stack fire-damage multipliers and burn-duration bonuses to maintain consistent DOT (damage-over-time).
Prioritize rolls with higher incendiary base damage and parts that increase fire rate or magazine capacity. Skyspanner Kratch is the noted source for farming the Hellfire.
Hellfire excels in crowd control through burn and splash damage, making it a strong choice for aggressive players who want continuous area pressure and reliable burn application.
Plasma Coil: Shock and Radiation Specialists
Plasma Coil is a high-fire-rate Maliwan SMG that alternates between Shock and Radiation elements, offering rapid status application for shields and health-within-targets respectively. Its lack of licensed parts keeps the rollout focused on elemental effectiveness and rate-of-fire tuning.
Players should aim for Shock rolls to strip shields quickly or Radiation to exploit DOT interactions with certain enemy types and synergies. The Primordial Guardian Timekeeper is the main farm source for Plasma Coil drops.
Plasma Coil fits builds that rely on elemental status stacking and rapid target-switching, especially in fights that require repeated shield breaks or perpetual radiation ticks.
Iconic and Unique Legendary SMGs
These weapons stand out for distinct mechanics that change playstyle: energy-transfer effects that fuel shields and abilities, magazine systems that lean into sustained fire, homing projectiles for reliable crowd control, and hybrid burst/rapid-fire designs for single-target burst damage.
Ohm I Got: Energy Transfer Perks
Ohm I Got channels energy-transfer perks that convert weapon damage into shield or ability resources. When it hits, a percentage of damage returns as an electric charge that replenishes the user’s shield or primes power-based passives. Players relying on skill cooldowns or shield gating see the biggest payoff because the transfer sustains defensive uptime without sacrificing offensive output.
It pairs best with builds that stack electrical damage or shield-focused mods. Recommended stat priorities: high elemental amp, moderate fire rate, and stability to keep consecutive hits on target. In team play, Ohm I Got supports frontline durability while still dealing solid single-target DPS.
Luty Madlad: Unlimited Magazine Mechanics
Luty Madlad implements an unlimited magazine mechanic by drawing on an internal energy reservoir instead of traditional ammo. When activated, the gun fires until the reservoir depletes, then forces a short recharge window rather than a reload animation. This design favors long sustained engagements and strafing playstyles where stopping to reload costs more than a recharge cooldown.
Players should pair it with damage-over-time or bleed effects to maximize uptime across the magazine cycle. Recommended mods include cooldown reduction and recoil control to exploit long uninterrupted bursts. Luty Madlad excels at suppressing groups and maintaining damage on bosses without repeated reload interruptions.
Birt’s Bees: Homing Projectiles
Birt’s Bees fires erratic, insect-like projectiles that later home in on enemies, turning questionable accuracy into reliable crowd control. The projectiles disperse on exit, then correct toward targets, making the weapon forgiving at close-to-mid range and effective against clustered mobs. It scales with projectile count and homing strength rather than raw bullet damage.
This SMG performs well with splash or elemental combos because the homing rounds ensure status effects land. Prioritize projectiles-per-shot, elemental chance, and reload speed for optimal use. In PvE, Birt’s Bees removes the need for pinpoint aim and excels at clearing tightly packed enemies.
Onslaught: Burst Damage and Rapid Fire
Onslaught blends short high-damage bursts with a rapid-fire follow-up, giving players a two-phase combat rhythm: initial burst to chunk shields or armor, then sustained fire to finish. The weapon’s burst module increases per-shot damage for the first few bullets, then transitions to a high fire-rate mode that trades per-shot power for volume. This dynamic suits hybrid builds that alternate between precision strikes and spray damage.
Best practice: use the burst phase against single strong targets, then switch to continuous fire for groups or armor-broken enemies. Recommended stats include high critical multiplier, fire-rate tuning, and magazine resilience. Onslaught provides flexible crowd control and boss-killing capability when timed correctly.
