Despite being goofy and fun loving, Claudia often employs tactical wit and strategy in her battles, she is not one of the most physically powerful of the group. Claudia is not an extremely strong person, but she is stronger than your average person. She can pick up and break boulders but struggles with it(Where as Nero, Killua Kosaka, and Tristan Belmont can pick them up and break them with extreme ease.). Claudia's weapon is her guitar made from a special and rare, almost indestructible metal. She uses it to bash her enemies and create hypnotic, or painful music.
