Barbeloth

Barbeloth, codenamed 'B', is a member of the enigmatic Hexenzirkel (Circle of Witches) in the game Genshin Impact. She is Mona's master and a powerful mage specializing in hydromancy and astrology, often referred to as the 'Old Hag' by Mona. Barbeloth is rumored to possess immense power, rivaling Alice, another member of the Hexenzirkel. While she focuses on specific magical disciplines, her power is considered considerable. Barbeloth also has a fondness for hats and even helped Alice choose Klee's signature hat. Her exact whereabouts and details remain a mystery, but her position as a member of the Hexenzirkel suggests a significant role in the Genshin Impact world.
