Borderlands 4 Kill Major Bosses To Get The Legendary Gear Loot
Posted: Sep 15, 2025 Views: 82
From the moment you launch Borderlands 4, you'll be transported to the dangerous and challenging planet of Kairos, where you'll battle your way through the main story while strengthening yourself.
Like most games, Borderlands 4 offers multiple quests along the way, some of which feature dangerous bosses to defeat. Fortunately, these bosses also offer loot.
Below, we'll cover all the major bosses you might encounter, their rewards, and strategies for defeating them, based on the known playable content in Borderlands 4.
Idolator Sol
This boss is part of the quest Rush the Gate and can be found in Fortress I Indomita in The Fadefields. Although he appears large, he only has three flesh bars, requiring you to deal sufficient burn damage to defeat him.
To achieve this, it's recommended to wait until the boss fires its locust cannisters before attacking. You can pick up and throw the green locust cannisters to destroy the boss's armor, making him more vulnerable.
Beyond your normal attacks, you can also shoot the green orbs on the boss for extra damage, quickly ending the fight and earning Borderlands 4 cash and the following legendary gear:
- Golden God - Shotgun
- Goremaster - Shotgun
- Kickballer - Shotgun
- Onslaught - SMG
- Bio-Robot - Harlowe Class Mod
- Dancer - Rafa Class Mod
- Furnace - Amon Class Mod
- Technomaster - Vex Class Mod
Vile Lictor
This boss is encountered during the quest His Vile Sanctum in Terminus Range deep within Windspear region. It appears as a purple, floating behemoth.
Perhaps because quests focus more on unlocking more story content and providing rewards, Vile Lictor isn't particularly difficult to defeat. Initially, the boss has an armor bar and, upon emerging from the machine, uses Corrosive and Cryo abilities.
Once his armor is depleted, Vile Lictor begins a new phase, where you need to seize the opportunity to use the Impact ability to destroy his shields.
In addition, throughout both phases of Vile Lictor's fight, he will continuously fire deadly beams at you from his multiple hands, requiring you to defeat them while simultaneously damaging the boss.
Vile Lictor loot pool includes:
- Super Soldier - Shield
- Ruby's Grasp - Pistol
- Blacksmith - Amon Class Mod
- Undead Eye - Vex Class Mod
- Instigator - Rafa Class Mod
- Generator - Harlowe Class Mod
- Blockbuster
Callis, The Ripper Queen
After completing Her Flaming Vision quest, you'll need to travel to Fallen Crown area of Carcadia Burn and find Moon-Called Throne to encounter this boss.
Before starting this boss fight, make sure you have a weapon that deals Corrosive or Cryo damage to break through the boss's shield, allowing you to deal more damage with Incendiary weapons.
As for Callis's abilities, be careful of her metal arms, which attempt to stomp you and cause flaming ruptures. Also, one of the best times to attack her is when she's retreating and web-slinging you. Defeating her has a chance to drop:
- Queen's Rest - Pistol
- Illusionist - Vex Class Mod
- Viking - Amon Class Mod
- Esgrimidor - Rafa Class Mod
- Skeptic - Harlowe Class Mod
- Pandoran Memento - Shield
Moon-Maddened Callis
Another Callis! Similar in appearance and combat mechanics to Callis, the Ripper Queen, this boss isn't too difficult to defeat. After completing Another Day, Another Universe quest, you'll encounter this boss at the end of Elpis Orbital Shatterfield.
While similar in mechanics, Moon-Maddened Callis has double the armor and flesh bonuses of her predecessor. During the fight, she tends to stay in a ranged position, attacking with her barbed tail while covering the battlefield with webs.
Fortunately, you can still attack her using Corrosive or Cryo damage stacked with Incendiary weapons, but the fight may take longer. Note that this boss has no unique loot, only a random drop of Gamma Void.
Gamma Void is a heavy weapon ordnance. Its Radiant Exposure ability creates a singularity that lasts for 10 seconds, during which targeted enemies suffer 40% continuous radiation damage.
Timekeeper
This boss is located in Upper Dominion in Dominion City. Upon reaching this location, take the elevator up to encounter the boss. This boss actually consists of two characters, or you can think of it as two phases: Timekeeper and Primordial Guardian Timekeeper.
Timekeeper's main abilities include teleportation, blinding, and energy beams. You'll need to dodge his attacks while simultaneously penetrating his shields and armor and dealing damage.
After defeating Timekeeper, the fight enters the second phase, where Primordial Guardian Timekeeper appears. He has health bars and will stomp around to deal damage.
The main loot for this boss fight includes:
- Timekeeper's New Shield - Shield
- Symmetry - Sniper Rifle
- Star Helix - Assault Rifle
- Borstel Ballista - Sniper Rifle
Arjay
This boss is located in the same location as Timekeeper. If you're confident, you can continue the fight in Upper Dominion. During the fight, Arjay will launch Rippers, Vile enemies, and tornadoes to damage you.
Note that this boss currently does not reward legendary gear. So if you're not interested in pure combat, you can skip this boss fight until Arjay's loot is updated.
That's all for this guide! If your character hasn't yet acquired good gear or completed the main quest, start farming these bosses now!
