Paranormal shield

"Criminy! They've got paranormal shields now?! Resourceful little rascals! Luigi, the Poltergust 5000 should be able to make short work of their shields. Once you catch a ghost in your vortex, wait for the meter to charge, and then press . The power surge should be enough to disable their shields. Look lively!"

- Professor Elvin Gadd

A paranormal shield grants a ghost invincibility in Luigi's Mansion: Dark Moon until it is shattered by a Power Surge from Luigi's Poltergust 5000. Each paranormal shield is blue, green, or red, denoting the minimum level of Power Surge that will destroy it. In Dark Moon Quest, paranormal shields are introduced in mission Play Catch where a single Greenie in the Warehouse uses it. If the player does not collect enough money to unlock green and red Power Surges, ghosts that have green and red shields will have blue shields instead. In ScareScraper, only the Beetle Whisperer and its variations of them use the paranormal shield in normal mode. During harder modes, other ghosts such as Greenies use it.
