How to Get Legendary Class Mods in Borderlands 4

By Ambar Jimenez | 2025-09-14 12:52:57
In the adrenaline-fueled world of Borderlands 4, players are introduced to a fresh cast of Vault Hunters, each with their own unique abilities and playstyles. While skill points offer a way to customize and grow a character's strengths, the true power lies in a Legendary Class Mod. These coveted items are the ultimate key to creating an overpowered build, fundamentally changing how a Vault Hunter's skills function and amplifying their destructive potential.The hunt for these game-changing items is a core part of the endgame experience, and for players looking to nab a specific Legendary Class Mod, the quest leads to one of the most challenging bosses in the game. Here's a breakdown of where to find and farm these legendary drops and the incredible power they unlock for each of the four new Vault Hunters.

Borderlands 4: Get Legendary Class Mods

The Primordial Guardian of Legendary Loot

The primary source for all Legendary Class Mods in Borderlands 4 is the Primordial Guardian Inceptus. This formidable boss resides within the Arch of Inceptus in The Fadefields region. To even face this beast, players must first embark on a scavenger hunt to collect the three Vault Fragments scattered across the region.This is a familiar process for veteran Vault Hunters: locate and activate the three Silos in The Fadefields to receive hints about the fragment locations, then use the "Hot and Cold" meter on your HUD to track them down. Once all three fragments are collected, the Vault entrance will be revealed, and you can prepare to face Inceptus.While Inceptus is the dedicated source for these mods, it's important to note that the drops are a matter of luck. The loot table for this boss includes a wide range of legendary items, and the specific Class Mod that drops, if any, is completely random. This means you may need to farm Inceptus multiple times to get the mod you want, and even then, it might be for a different Vault Hunter than the one you are currently playing.

Legendary Class Mods and Their Effects

Each of the four Vault Hunters has a signature Legendary Class Mod that drastically alters their playstyle and offers powerful stat bonuses. Here's a closer look at each one:

Amon the Forgeknight: Chilling Elementalist

  • Skill Bonuses: +3, +2, +2, +2
  • Description: "Whenever an Affinity Skill gains a Stack, all unlocked Affinity Skills also gain a Stack. For each Stack of Affinity from all Affinity Skills, Amon gains increased Movement Speed."
  • Stat Increases: +35% Splash Damage, +30% Skill Damage

Amon's Chilling Elementalist mod transforms him from a brute into a highly mobile, elementalpowerhouse. By amplifying the effects of his "Affinity" skills, itallows him to quickly build up stacks of elemental damage buffs and gain a significant boost to his movement speed, making him a fast-paced,close-range menace. This mod is perfect for players who want to buildaround his elemental skill trees like Cybernetics and Vengeance,stacking Cryo and Incendiary damage for massive explosions and statuseffects.

Rafa the Exo-Soldier: Rewarding Filantropo

  • Skill Bonuses: +3, +2, +1, +1
  • Description: "Whenever Rafa retriggers his Action Skill, he spawns a free Grenade.If he has a Grenade equipped, he spawns one based on that. This Skillhas a 4 second cooldown."
  • Stat Increases: +20% Damage Dealt, +45% Ordnance Damage

The Rewarding Filantropo Class Mod for Rafa is a game-changer for players who love to usegrenades and ordnance. By spawning a free grenade every time hereactivates his action skill, this mod allows for an almost constantbarrage of explosive damage. The added bonuses to Damage Dealt andOrdnance Damage make every thrown grenade a small nuke, perfect forcrowd control and melting large groups of enemies. It synergizesparticularly well with builds focused on his Peacebreaker Cannons or the Apophis Lance, keeping the pressure on enemies with both gun andgrenade fire.

Vex the Siren: Electric Avatar

  • Skill Bonuses: +3, +2, +1, +1
  • Description: "Vex and her Minions deal increased Damage for each active Attunement,and gain Damage Reduction against each Elemental Type she is Attunedto."
  • Stat Increases: +36% Attunement Duration, +30% Reload Speed

For players who prefer a pet-based or elemental build, Vex's Electric Avatar is a must-have. This mod dramatically increases the damage output ofboth Vex and her summoned minions for every active elemental attunement. This encourages a versatile playstyle where the player constantlyswitches between elemental weapons to stack bonuses. The added damagereduction against attuned elements also makes Vex significantly moresurvivable, allowing her to stand her ground in the face of elementalthreats while her minions wreak havoc. The boost to Reload Speed is anadded bonus, ensuring she can keep her attunements active with minimaldowntime.

Harlowe the Gravitar: Atomic Driver

  • Skill Bonuses: +3, +2, +1, +1
  • Description: "Whenever Harlowe fires CHROMA Accelerator, she drains all but 1 of her Health and Amps CHROMA Accelerator. CHROMA Accelerator gains +20%Lifesteal."
  • Stat Increases: +20% Lifesteal, +36% Action Skill Cooldown Rate

Harlowe's Atomic Driver mod is designed for high-risk, high-reward gameplay. It taps into aclassic Borderlands mechanic by converting a massive portion of herhealth into a "damage amp" for her action skill, CHROMA Accelerator. While this leaves her incredibly vulnerable, the mod's built-inLifesteal and a high Action Skill Cooldown Rate allow her to quicklyregain her health by dealing massive damage. This mod is a perfect fitfor an aggressive playstyle that relies on rapid-fire action skill usage to dominate the battlefield, turning her into a glass cannon that cansustain herself through sheer destructive force.

The Legendary Class Mods in Borderlands 4 offer an unparalleled level of customization and power, allowingplayers to fine-tune their builds and conquer the most challengingcontent in the game. While the farm for them may be a grind, the uniqueabilities and stat bonuses they provide are well worth the effort. Nowget out there, collect those fragments, and prepare to face Primordial Guardian Inceptus for your chance at a legendary drop!
