Luigi's Mansion 3 takes players on a thrilling ghost-hunting journey through a massive, multi-themed hotel filled with clever puzzles and unique boss encounters. When you reach the 10th floor, known as the Tomb Suites, you are completely transported into an ancient Egyptian pyramid setting. Defeating the royal phantom ruling this floor requires quick reflexes, keen observation, and a solid understanding of your Poltergust G-00 mechanics.

Understanding the Pharaoh Queen Ghost Boss

The main antagonist of the Tomb Suites floor is Serpci, a spectral queen who utilizes a massive shield of sand molded into the shape of a pharaoh head. This protective sand sculpture makes her completely immune to direct vacuum attacks or your standard Strobulb flash during the initial stages of the fight. To compromise her defenses, players must focus entirely on dismantling her outer armor before attempting to deal any direct damage to her spirit form.

As the encounter progresses, Serpci will command her sand construct to execute aggressive maneuvers across the desert arena. She will send out lines of sandy cobras that track your movements or cause massive sand fists to slam down from above. Staying mobile and utilizing your burst jump ability is essential for dodging these dangerous area-of-effect hazards while preparing your counterattack.

How to Safely Break the Sand Armor

The secret to breaking through her formidable defense lies in using your Poltergust G-00 suction capability on the loose sand structure. Move close to the giant pharaoh head and begin vacuuming up the foundation to gradually reduce its overall size. You can use your Suction Shot tool or a steady stream of air to quickly tear down sections of the moving monument.

When the sand pharaoh launches smaller projectile attacks, it exposes weaker sections of its structural makeup. Watch the movement patterns closely and continuously deplete the sand levels until Serpci is forced out of her protective shell. Once she drops to the ground without her armor, she becomes temporarily vulnerable to a direct tactical strike.

Executing the Winning Battle Strategy

When the queen is exposed on the floor, quickly flash her with your Strobulb to stun her in place. Once she is disoriented, immediately latch onto her with your vacuum hose and begin pulling backward to drain her health pool. Slam her against the sandy ground multiple times to maximize your damage output before she retreats back into safety.

After each successful damage phase, Serpci will rebuild her sand fortress and increase the speed of her incoming attacks. She will begin launching spinning sand blades and executing faster charge attacks that require precise timing to avoid. Repeat the process of vacuuming her armor, stunning her form, and executing heavy slams until her health is fully depleted to secure the elevator button.
