Dedicated Boss Farming: How to get DRILLER HOLE in Borderlands 4

The quickest path to get DRILLER HOLE in Borderlands 4, is by accessing a specific Fast Travel spot and minimizing combat:

• Fast Travel Location: Begin your run from LowRise Safe House in Arcadia's cargo area.

• Initial Path: From the Safe House, take a southwest course through the first gap (typically requiring a vehicle jump) and proceed straight across the main bridge.

• Arena Access: Travel through the large opening directly after the bridge, which leads you straight into an elevator shaft. The elevator bypasses the lengthy story-driven fight sequence that you just experienced with Zane.

• Final Approach: When you descend via the elevator, you'll be near a Save Station, a merchant, and the final jump point that leads you straight into the arena of the boss.

Making Use of the Moxxi's Big Encore Feature

During the time Driller Hole was writing this guide, his Big Encore boss for the week was Moxxi. That means his rare drop rate is significantly boosted for a short time. Always examine the machine near the boss entrance:

• Standard Entry: Enters you into the arena normally.

• Big Encore Entry: Costs 100 Iridium but has a much higher chance to receive his exclusive drops. This is the most efficient way to farm all three items simultaneously.

DRILLER HOLE's Exclusive Legendary Loot Pool

Driller Hole has a valuable loot pool consisting of three unique legendary items: an Assault Rifle, a Pistol, and a Grenade Mod.

GMR Assault Rifle

• Manufacturer: Atlas

• Special Gold Text: "Big Name Hunter."

• Red Text Bonus: When zoomed in, damage is increased by 100%, shot price is doubled (100% increase), and fire rate is decreased by 80%.

• Analysis: This pistol is a straight-up beast when hip-fired with huge sustained damage. While it's great to have the damage bonus on ADS, the aggressive recoil does make it difficult to stay on target, so it's better suited to burst firing or mid-to-long range where precision isn't as much of a concern. The high DPS ability makes this an Atlas necessity.

Kanagawa's Revenge Pistol

• Manufacturer: Maliwan (Mostly drops with a Jacobs attachment)

• Special Gold Text: "Winter Storm Cloud."

• Red, Yellow, or Blue Text Perk: "You might hurt someone."

• Effect: Shoots projectiles that summon small, elemental storm clouds over enemies. The clouds release sustained damage, which is excellent for crowd control and elemental damage stacking. Jacobs accessory roll (critical hits that return projectiles to nearby enemies) is particularly deadly, filling the battlefield with a deadly mesh of elemental damage.

The Fuse. Grenade Mod

• Manufacturer: Tediore

• Effect: This grenade is a timed, elemental Bouncing Betty. When tossed, it sticks to an enemy or surface and bounces for a few seconds before exploding in a large elemental blast.

• Tactical Use: The Fuse has a noticeable delay, limiting its use for quick crowd control. As an aside, however, it can be extremely handy on large stationary bosses or defense battles where foes are grouped and never moving around. Look for rolls matching the elemental weakness of your target.

Optimizing Your Loot Runs to get DRILLER HOLE in Borderlands 4

By focusing your farming effort at Driller Hole for a Big Encore week, you significantly increase your chances of acquiring extremely coveted parts and accessories. In a lucky run, one can observe that various devoted drops such as a Kanagawa's Revenge with a Jacobs accessory and a COV magazine (basically granting infinite ammo until the weapon overheats) can drop simultaneously.

For serious Vault Hunters who want to complete their sets, this boss offers a top-of-the-line, repeatable fight. Remember the more Iridium you use on the Big Encore, the better the loot efficiency you'll have. If you are determined to get DRILLER HOLE on Borderlands 4's best-rolled Borderlands, this farming route is your most reliable strategy.
