Luigi’s Mansion 3 Boss Fight Guide: How to Beat Every Floor Boss

by Ali Haider

Luigi’s Mansion 3 is more than just a ghost-hunting adventure—it’s a masterclass in puzzle-driven boss battles. Each floor of The Last Resort hotel introduces a new, often theatrically themed foe, each with unique attacks and weaknesses to exploit. While some early fights are relatively simple, later encounters demand sharp reflexes and clever use of both Luigi and Gooigi’s abilities.

This guide breaks down every major boss fight floor-by-floor, explaining their attack patterns, weak points, and the best strategies to defeat them.

Floor B1 – Steward

Your first real test as a ghost hunter begins in the basement against Steward, a hotel worker who uses luggage as both a shield and a projectile. The trick here is to disarm him. When he hides behind suitcases, use the Poltergust G-00 to suck them away. Once he’s exposed, blast him with the Strobulb to stun him, then vacuum and slam him repeatedly until he’s defeated. This fight is designed to teach you the core combat rhythm—stun, vacuum, and slam.

Floor 5 – Chambrea

Chambrea, the maid ghost, conceals Luigi’s missing suitcase inside her ectoplasmic body. Begin by stunning her with the Strobulb, then fire a plunger shot at her torso to pull out the suitcase. Once stunned, slam her into the ground several times before she escapes to another room. Use the Dark-Light Device to track her trail of ghostly residue to her new location and repeat the process until she’s captured.

Floor 3 – Kruller

Kruller, the mall security guard, is one of the more comical yet challenging early bosses. This fight requires Gooigi, as some sections are only accessible to your gelatinous companion. Kruller will attempt to blind you with his flashlight and attack using his water pistol—Gooigi’s main weakness. Dodge his shots carefully, then wait until he puts on his sunglasses. Use the Poltergust G-00 to pull the glasses off, flash him with the Strobulb, and begin your slam combo. Once you get the timing right, this fight becomes much easier.

Floor 2 – Chef Soufflé

Chef Soufflé uses a large frying pan as his shield, blocking all light attacks. Your first goal is to disarm him—fire a plunger shot at his pan and pull it away. Once his defense is down, hit him with a Strobulb flash, vacuum him with the Poltergust G-00, and slam him into the kitchen floor. Be careful after each attack, as the chef briefly enters an invincible phase before resetting his stance. Repeat the process until he’s defeated.

Floor 4 – Amadeus Wolfgeist

The elegant yet temperamental pianist Amadeus Wolfgeist commands an entire orchestra of ghostly instruments. During this multi-phase battle in the concert hall, dodge flying chairs and other furniture until Amadeus animates his piano. When the piano charges at you, hit it with a plunger to expose Amadeus inside. Slam the piano into the stage floor to destroy it. Once he emerges in his true form, use the Strobulb to stun him and then the Poltergust G-00 to deal heavy damage. Repeat until the maestro takes his final bow.

Floor 6 – King MacFrights

This medieval-themed boss fight pits Luigi against King MacFrights, a ghostly knight riding a spectral horse. Patience is key—wait for the king to lower his guard and prepare to attack, then flash him with the Strobulb. As his armor begins to break apart, use your plunger to remove the remaining pieces. Once exposed, continue alternating between dodging his charges and attacking when vulnerable. When his armor shatters completely, finish the fight with a well-timed slam combo.

Floor 7 – Dr. Potter

Dr. Potter, the eccentric ghost botanist, hides behind a massive carnivorous plant. To damage him, you must first find and grab a chainsaw using the Poltergust. Wait until the plant lunges, then counter with the saw to cut through its stalk. Once Dr. Potter is left unprotected, stun him with the Strobulb and slam him into the dirt. This fight is all about timing—stay close to the plant, but react quickly before it can trap you.

Additional Boss Tips

  • Use Gooigi Wisely: Several bosses, especially Kruller and Dr. Potter, require coordination between Luigi and Gooigi.
  • Flash Before You Slam: The Strobulb remains the most reliable way to stun any ghost boss before engaging.
  • Watch Environmental Cues: Many fights rely on items in the arena—plungers, grates, or objects to throw can make all the difference.
  • Dark-Light Device: For enemies that vanish or relocate, this device reveals their traces and hidden doorways.
