Mona Megistus is a playable Hydro character in Genshin Impact.

An astrologist of great skill and equally-great pride, Mona has taken up residence in Mondstadt to avoid incurring the wrath of her master after unwittingly reading the latter's diary.



A mysterious young astrologer who proclaims herself to be "Astrologist Mona Megistus," and who possesses abilities to match the title. Erudite, but prideful. Though she is often strapped for cash and lives a life of thrift, she is resolved to never use astrology for profit... It is this very resolution that has caused her to constantly fret about money.

In-game character attributes text

Mona is unique among astrologers — others may speak with great ostentation for money, but Mona has never done so. Nor does she dress up or mince her words, even if her results are unpleasant to hear: "You won't amount to anything even if you join the Adventurers' Guild." "You've got no chance with him. In fact, he will soon leave you" — such is the nature of her rejoinders.
Her blunt nature has resulted in plummeting numbers of people coming to have their fortunes told. But Mona isn't one to complain, for that just leaves her with more time for her personal research.
But when one speaks of research, one also speaks of the necessity of purchasing texts and research apparatus. Mona's only income comes from her contributions to The Steambird's "All Things Astrological" column. Every paycheck is spent first on her research. Books from Liyue, an astrolabe from Sumeru... all of these come with a hefty price tag, and by the time Mona regains her senses, there's only enough of her income left for her to scrape by each month.
”It matters not. Astrologers must rid themselves of material desires. Only by ridding oneself of clutter can one see the true world around them." So says Mona, coughing loudly all the while to cover the sound of her growling stomach.
Today, too, is another day Mona worries about Mora.

Description from forum announcement[5]

Mona is an astrologist who takes her passion seriously. She is very knowledgeable in this subject in part and respects her master, although it is implied that she is also scared of them. She combines her astrology skills with hydromancy, which makes her a well-known, if still growing astrologist. In part due to her astrology, Mona can tell whether or not a person is lying, can sense their intentions from a single glance, being capable of seeing their fate and is able to accurately deduce a person's traits just from knowing what their constellation is.

Being obsessed with astrology gives Mona a sense of pride, but this also serves as a double-edged sword; any Mora she gets her hands on is immediately spent on astrology-related materials, regardless of its cost. She only realizes too late when she has run out of Mora to meet her daily needs, often going without shelter or food for days on end; in the times that she does eat, she prefers cost-effective foods such as salads. She does not tolerate those who disrespect her.[6]


Mona has light skin, a curvy build, and pale green eyes. She also has long black hair which she wears in two pigtails, and wears a compass-like gold earring on her left ear. The ends of Mona's pigtails are decorated with two gold compass ornaments.

Mona wears a purple and black leotard with gold lining. She wears purple sleeves and black gloves, along with a short purple cloak with red lining, buttoned with a compass ornament hanging above her chest. On top of her head rests a purple witch hat, decorated with gold decals, black ribbon and another compass ornament. A similar one is seen wrapped around her right thigh.
