Borderlands 4 Defeat Callis The Ripper Queen To Complete Her Flaming Vision Quest

Posted: Sep 28, 2025 Views: 35

While Borderlands 4 offers a generous degree of exploration, it's recommended that you prioritize completing the main quests within your capabilities to earn XP and gain a deeper understanding of the game's story and major bosses.

The main quest system consists of multiple quest lines, one of which is Ripper Queen storyline. This time, we'll introduce the final quest in that line, Her Flaming Vision.

We'll explain the prerequisites for accessing this quest and how to defeat the final boss, Callis.

Borderlands 4 Defeat Callis The Ripper Queen To Complete Her Flaming Vision Quest

Step 1: Skip The Ramp Test

After completing the previous main quest, you'll be transported back to Carcadia City. Next, you'll need to find and speak with NPC Levaine on the west side of the plateau to trigger the next quest.

Although Levaine was previously located in Leaders' Chamber, you won't be able to interact with her in this section, even though you can see her there.

During the conversation, you'll see rockets launching from the northwest edge of Carcadia Burn, located in Fallen Crown Crater, the lair of boss Callis. To reach it, you'll need to cross a rift.

To do this, you'll need to find another NPC, Zane, to trigger a ramp test to see if you can currently cross the rift - which is obviously impossible.

We recommend speaking with Zane directly to skip the test. If you choose to complete the test on your own and accidentally fall into the abyss, you'll end up spending extra BL4 cash to respawn, which is not worth it.

Step 2: Find The Spatial Accelerator

After skipping the test, the quest guide will instruct you to head to Gunkwork on the northern edge of Carcadia Burn to find a usable spatial accelerator.

Gunkwork is one of the most dangerous Ripper facilities in the game. You could encounter any imaginable enemy within, so be sure to bring your best gear and plenty of combat supplies.

After clearing all enemies, investigate the giant crawler to the northeast of the facility. Once you're close enough, Zane will instruct you to continue your search by heading toward the massive gate on the northwest side of the factory, then Drilldozer Deluxe will appear.

To avoid being run over by the drill, you'll need to immediately avoid its path. Then, climb to the top of the factory wall, glide onto the drill's platform, and interact with the panel at the front. This will prompt you to obtain a keycard that allows you to override the drill.

How To Obtain The Keycard?

Once prompted, backtrack and time your jump onto the drill. Ride it to reach the crawler, where you'll encounter a group of enemies on top of the crawler. Defeat them, and Holey Moley, the site foreman holding the keycard, will appear.

Defeat this mini-boss to obtain the keycard, which you can then insert into the drill's override panel to open a door on the platform below.

After jumping down, turn all the valves in the room to overheat the drill's engine. This will allow you to retrieve the space accelerator from the center of the room. Return to Zane with the item.

Step 3: Reach Boss Callis' Lair

Place the space accelerator on the machine next to Zane to activate the generators on both sides. Now, mount your digi-runner and use the machine's power to catapult you to the other side of the rift, on the path to the boss's location.

Remember to always aim straight ahead during the catapult. Don't try to jump or glide just because you might fall. This will ensure you land safely in a cave below the rim of the crater.

Continue forward, killing all enemies along the way until you reach Moon-Called Throne. You'll need to repeatedly enter several rooms here, defeating the rippers within, and then use ECHO-4 to crack the final door in the final room.

Several waves of enemies will appear during the cracking process, disrupting ECHO-4's work; you'll need to eliminate them promptly. Once you've completed the cracking, you can jump into the pit containing the grinding wheel with your gear to begin the final boss battle.

Step 4: Defeat Callis, The Ripper Queen

This boss is characterized by its thick health bar and powerful attacks. Her weak spot is its head, but she moves around and changes positions frequently during the fight, making it difficult to consistently aim for it.

For this reason, it's recommended to aim for her center of mass most of the time, then seize the opportunity when she lands and stands to fire to land as many headshots as possible.

In addition, this boss's armor is very strong, so you must bring at least one weapon with good corrosive damage to destroy her initial health, as well as Callis's helpers and minions.

After her armor wears off, Callis becomes briefly invincible and creates shadow clones. These clones slow you down, so you'll need to avoid them while continuously attacking with your highest-damage weapon until the boss is defeated.

It's important to note that the minions summoned by the boss will often charge directly at you and damage you by exploding at close range. You'll need to eliminate them with grenades or other AoE attacks before they reach you.

Another key helper for Callis is Tabnak, The Ripper Prince. Most of the time, you don't need to defeat him; just dodge Ripper Orbs he throws mid-air.

After the battle, you'll claim your loot and the quest item, Command Bolt. Return to Carcadia City, speak to Levaine, and give her the item. This completes Her Flaming Vision quest and allows you to move on to the next step.

If the later quests seem too challenging, you can start by farming XP and gear in small increments to improve your character's abilities before continuing with the remaining quest lines. Good luck!
