Exploring the top floor of The Last Resort hotel in Luigi's Mansion 3 presents players with complex puzzles and hidden secrets. Locating all six gems on Floor 15, known as the Master Suite, requires clever use of Luigi and Gooigi's abilities. Collecting these final treasures completes your floor set and brings you one step closer to achieving full completion.
Mastering Shadow Puzzles for the Clear Gem
In the main hallway, players will encounter a statue placed in front of a wall painting. By rotating the statue, you must align its cast shadow with the silhouette of the artwork behind it. Adjusting the angles properly reveals the clear gem alongside a bonus stash of gold coins.
Unlocking Secret Rooms with Poltergust Mechanics
Navigating the various suite chambers demands thorough exploration and environmental interaction. In the library area, activating the windmill mechanism by blowing air with the Poltergust turns the floor platform. This action exposes a hidden cage where Gooigi can slip inside to pull a deactivating lever.
Navigating High Structures and Cages
Reaching elevated spots in the Master Suite requires precise teamwork between Luigi and his gooey counterpart. In the master bedroom area, players must ascend using the rocking balance platform. Once at the highest point, Gooigi can pass directly through metal bars to snatch the gem sitting at the very top.
Clearing the Final Floor Gem Set
The remaining gems require careful observation of pipes, hidden switches, and environmental objects throughout the 15F layout. Using the Dark-Light Device often exposes invisible elements that lead to concealed alcoves. Securing every single gem on this floor allows players to return to Professor E. Gadd's lab to claim special gallery rewards.
