Exploring the Grand Lobby on the first floor of Luigi's Mansion 3 introduces players to the foundational mechanics of gem collecting. Finding all six hidden gems on 1F requires keen observation and clever use of Luigi's gadgets, including the Suction Shot and the Dark-Light Device. This guide breaks down exact steps to locate every 1F gem so you can complete your hotel collection efficiently.
Finding the White and Purple Gems
The White Gem is concealed inside a couch located on the left side of the main lobby area. To reveal it, shine your Dark-Light Device on the missing sofa until it materializes, then defeat the spirit that appears. Once the spirit is cleared, the white gem drops directly onto the floor for pickup.
For the Purple Gem, head over to the receptionist desk situated on the front right side of the lobby floor. Shoot a Suction Shot at the glowing emblem behind the counter and pull the plunger to shatter the wooden structure. The purple gem will pop out immediately, allowing you to collect it without hassle.
Unlocking the Red and Blue Gems
The Red Gem is located behind the large main desk where you first check into the hotel. Use Gooigi to slip through the metal gate behind the counter and interact with the hidden wall switch. Activating this mechanism opens a secret compartment that drops the red gem right into your hands.
To obtain the Blue Gem, walk toward the far left corner of the lobby where a prominent glass display case sits. Use your Suction Shot on the front glass panel and slam it down to shatter the barrier. You can then grab the blue gem resting inside the broken display case.
Locating the Green and Yellow Gems
The Green Gem requires utilizing the central elevator shaft area located on the main floor. Use your Poltergust G-00 to blow air onto the potted plant near the elevator until it breaks open completely. The green gem drops from the foliage directly onto the carpeted hallway.
Finally, obtaining the Yellow Gem demands a cooperative effort between Luigi and Gooigi near the lobby entrance. Position Luigi on one side of the circular pressure plate and send Gooigi to stand on the opposite side. This action lowers the central chandelier, enabling you to vacuum up the yellow gem hanging from the middle fixture.
Tips for Completing Floor 1F Collection
Completing the entire set of gems on the first floor rewards players with a special accomplishment marker in their collection menu. If you miss any of these items during your initial walkthrough, you can always return to 1F later in your adventure once you have unlocked all upgraded abilities. Utilizing Gooigi effectively makes backtracking through earlier hotel floors fast and straightforward.
