Reaching the 15th Floor, also known as the Master Suite, in Luigi's Mansion 3 represents the ultimate test of exploration and puzzle-solving skills. Collecting all six hidden gemstones on this final penthouse level requires clever utilization of both Luigi and Gooigi, along with careful manipulation of the environment. Unlocking every gem brings players one step closer to achieving complete 100% completion in Professor E. Gadd's collection.
Finding the Lounge and Bedroom Gemstones
The clear gem in the Master Suite is obtained by solving a shadow puzzle located in the hallway. By rotating the nearby statue to match the shadow silhouette on the wall, Luigi unlocks the hidden compartment holding the treasure. This straightforward puzzle highlights the importance of observing environmental clues before rushing into new areas.
For the gem located in the master bedroom, players must navigate a tricky rocking platform to reach the upper height. Once at the top, send Gooigi through the metal cage bars to grab the jewel sitting safely inside. Coordination between characters is essential here to prevent slipping off the moving structure.
Exploring the Master Bathroom and Pipe Secrets
Inside the luxurious master bathroom, players will find another collectible hiding under the floorboards. Using Gooigi to travel down the drain pipe allows access to the lower plumbing system where the jewel is tucked away. Clearing obstacles underwater or turning valves restores access so Gooigi can retrieve the item cleanly.
Another gem requires operating environmental mechanisms such as sinks and wall switches in tandem. Having Luigi interact with one element while Gooigi handles the other opens secret compartments containing gold and collectibles. Taking time to test every interactive fixture in the room ensures no hidden reward is overlooked.
Unlocking the Remaining Master Suite Collectibles
Navigating through the remaining chambers of 15F involves maneuvering past complex security screens and hidden doors. Deactivating electrical hazards by pulling hidden levers grants safe access to caged alcoves housing valuable gems. Patience and timing are critical when timing movements around moving laser traps.
After securing all six gemstones on Floor 15, players can return to E. Gadd's lab gallery to view their complete set. Finishing the floor set rewards dedicated completionists with special cosmetic items for Luigi's equipment. Mastering these final puzzles serves as a fitting culmination to the haunted hotel adventure.
