Finding a specific legendary weapon in Borderlands 4 can be a daunting task due to their incredibly low world drop rates. Instead of relying on random chance, savvy Vault Hunters target dedicated loot sources. For the devastating Jakobs Hot Slugger shotgun, that means farming a specific boss. This comprehensive guide will walk you through every step to locate, defeat, and claim your prize.
Locating the Boss: The Callous Harbinger of Annihilating Death
Your journey for the Hot Slugger begins not with a random enemy, but with a dedicated boss fight against the intimidatingly named
Callous Harbinger of Annihilating Death.
Prerequisite: You must first progress through the main story campaign until you gain the ability to leave the starting area of
The Fadefields. Your destination is the eastern region known as the
Terminus Range.
Finding the Bunker:
Navigate to the eastern mountains of the Terminus Range to find Craven's Nook, an Order bunker.As you approach, the location will automatically mark on your in-game compass.Let your Echo-4 device guide you through the surrounding cave network to the bunker's entrance.
Gaining Entry:The bunker door is sealed with reinforced Order armor. To break in:
- Look to the left of the entrance for a bio canister dispenser on a cliff edge.
- Grab a canister and throw it directly at the door to melt the locks and gain access.
Conquering the Callous Harbinger of Annihilating Death
Inside the bunker, you'll fight through waves of Order synths. Work your waythrough the complex by grappling through vents and ascending elevatorshafts until you reach the boss arena.
The Callous Harbinger is a large, slow-moving target, but it makes up forits lack of speed with a devastating array of area-of-effect attacks.Its primary weaknesses are Shock, Corrosive, and Cryo elemental damage.
Boss Attack Patterns & Strategies:
- Slam Attack: The boss raises its glowing fists and slams the ground, creating a forward shockwave. Simply jump to avoid all damage.
- Charge Attack: It will lower its shield and charge directly at you. Use a dash move to quickly sidestep and retaliate.
- Missile Barrage: When its shield glows, immediately seek cover. It will unleash a volley of missiles in a straight line ahead.
- Diamond Bullet Hell: Its shield will float above its head, firing lasers and releasing aspread of diamond-shaped projectiles in all directions. Find cover until this attack subsides.
- Energy Streaks: In later phases, raising its fists will release radial energy waves.Look for the gaps between streaks and jump into one to avoid damage.
- Elemental Puddles: The boss will stand still and summon damaging elemental pools on theground (e.g., poison goo). Continuously move to avoid standing in them.
- Mounted Turret Mode: The shield transforms into a turret, and the boss will fire sustainedlasers. Strafe and circle the boss to easily avoid these beams.
Farming for the Hot Slugger Drop
Once defeated, the Callous Harbinger has a chance to drop the legendary HotSlugger shotgun. If it doesn't drop on your first try, don't worry. Youcan replay this boss fight infinitely using Moxxi's Big Encore feature at the end of the mission to farm for your prize.
Why the Hot Slugger is Worth the Farm
The Hot Slugger is not just any legendary; it's a top-tier Jakobs weapon with a unique and powerful effect.
- Massive Damage Stacks: The standout perk is "Consecutive Hits". With every kill, you gain a +30% bonus to all damage dealt (gun, grenade, action skill). This stacks up to three times for a massive +90% total damage increase.
- Jakobs Ricochet: True to the manufacturer's style, critical hits with the Hot Sluggerwill ricochet bullets to nearby enemies, making it excellent for crowdcontrol.
- Trade-Off: The only downside is its single-shot magazine. You must fire and reload after every shot, making accuracy crucial.
This combination of perks makes the Hot Slugger an exceptional weapon formelting through tough bosses and large groups of enemies, securing itsplace as a must-have item in your arsenal.
