Luigi's Mansion 3 Coliseum Boss Strategy Guide

8 August 2026 | 88

Navigating the ghostly corridors of the Last Resort hotel brings players face-to-face with some of the most creative encounters in modern gaming. Floor 6 introduces a medieval nightmare known as Castle MacFrights, which culminates in a chaotic showdown inside a massive arena. Overcoming the resident monarch requires patience, precise timing, and a deep understanding of the unique combat mechanics available to our green-clad hero.

Surviving the Jousting Phase

King MacFrights enters the arena riding a wooden hobby horse and protected by thick, impenetrable armor. He will aggressively charge across the dirt floor attempting to spear Luigi with a long jousting lance. Players must stay light on their feet and prepare to use the Burst function at the exact moment the king approaches to avoid massive damage.

Attempting to blind the king with the Strobulb while he is charging will result in failure because his shield blocks the light flash entirely. Instead, wait for him to complete his charge and momentarily get stuck in the arena walls. This brief window provides the perfect opportunity to fire a Suction Shot directly onto his exposed chest target.

Breaking the Royal Shields

Once the plunger firmly adheres to the royal armor, slam the king repeatedly against the stadium floor to break his defensive gear apart. Stripping away the shield and helmet forces the ghostly ruler into a desperate ground-based combat style. He will spin frantically across the area with his sword outstretched, creating a hazardous whirlwind that requires broad circular movement to avoid.

After the spinning animation concludes, the boss becomes temporarily dizzy and vulnerable to basic ghost-hunting techniques. Flash him quickly with the Strobulb to stun him in place before he can regain his royal composure. With the target fully incapacitated, latch on with the Poltergust G-00 and begin draining his remaining health pool.

Mastering the Final Confrontation

As the battle reaches its final phase, the speed of the enemy attacks increases significantly to challenge player reflexes. King MacFrights will mix up his charging patterns and drop dangerous obstacles onto the field to restrict your overall movement space. Utilizing Gooigi as a diversion can help redirect the boss's tracking away from the vulnerable real Luigi.

Maintaining a safe distance allows players to accurately predict where the final charging paths will end. Repeat the stun and slam sequence one last time to fully clear the arena and claim the valuable elevator button. Defeating this medieval menace clears the path forward to explore the higher levels of the haunted establishment.
