Luigi's Mansion 3 is full of secret treasures to discover on every floor. So we're here to help you overcome the pain and show you exactly where to find them and how to get them.
We'll start with the basement, at the very bottom of the hotel, where there are six relatively easy to find gems. Just a note, make sure you have all the weapons and bonuses before you collect each gem as you will have to use your entire arsenal to find them.
With that in mind, here's where to find each of them on floor B1:
- White gem: To the right of the E-Gadd base, you will notice a car. Vacuum the sheet and use your flashlight to unlock the chest. The gem will then come out.
- Red Gem: In the garage on the right is an electric barrier, use Gooigi to go through it and use a suction cup attack on the electric box on the left. Use your flashlight to activate the generator and collect the gem.
- Blue Gem: Go to the right of the garage and you will find a secret vent in the back corner. Use your suction cup attack to pull it off. Go through the new area and go up a flight of stairs to the top. You will see the gem as you ascend. Use Gooigi to go through a hole on the ground and collect the gem.
- Green Gem: In the washing machine. Use your suction cup attack to open the door.
- Purple Gem: In a table next to the door leading to the garage in the hallway. Use your black light to get it out of the paint.
- Gem Yellow: Go up the stairs to the first floor. At the top, use Gooigi to descend a vent to collect the yellow gem hidden below.
