Chambrea

Chambrea is the second boss encountered in Luigi's Mansion 3. She is first encountered on the first floor of the Grand Lobby and is subsequently fought in various hotel rooms in RIP Suites after Luigi locates the room to retrieve a briefcase. Defeating Chambrea rewards Luigi with the elevator button to the third floor and allows E. Gadd to supply Luigi with Gooigi. Her name is a play on "chambermaid."

Appearance
Chambrea is a purple female ghost with pink eyes in a standard maid uniform and carries a hand duster. She has her hair tied in a bun, as well as a sweet-sounding voice. In the intro, she can be seen wearing a mask in disguise.

History
She is first seen traversing the elevator area in the Grand Lobby, dusting various furniture and surfaces in the room.

When next seen during Luigi's time on the fifth floor, she is found in Room 508 and is still following her duty to clean and dust. She is distracted when she spots E. Gadd's briefcase and examines it with interest. Luigi, watching through the door, panics and steps inside with no heed to the door slamming shut. Chambrea turns around and is startled by Luigi's presence, tightly withholding the briefcase, before swallowing it and attempting to float through the wall into the next room, though she has trouble passing through due to the solid briefcase in her now enlarged stomach.

Luigi pursues and combats her in various rooms before eventually pulling the briefcase through the surface of her stomach and finally capturing her. In the gallery she happily dusts her containment jar.

Battle
Chambrea will be hiding in a room she has entered, but can be quickly spotted and drawn from her hiding place. She has few offensive actions, as she will ram Luigi with her belly when she is not stunned or being sucked.

However, her most challenging aspect is her immunity to being outright captured by the Poltergust G-00, as she cannot lose health from suction. She will instead simply become stuck in the maw of the Poltergust due to the solid briefcase inside her belly, where she will laugh and harass Luigi with her duster until he releases her.

Though she is immune to suction, she is vulnerable to the plunger. Luigi can stick a plunger to her stomach and pull the end of it, from where Luigi can slam her repeatedly around the room to reduce her health.

Once Chambrea's HP reaches 0, the briefcase will launch out from her stomach as she dramatically waves her duster until she is ultimately captured.

Trivia

 * Chambrea is the only ghost with an elevator button to not have the elevator button burst out of the Poltergust G-00, rather it just drops out of the nozzle into Luigi's hand.
