Genshin Impact Mona guide – the best build

The best build for Genshin Impact’s Mona

Genshin Impact's Mona looking towards you

Mona is an extremely skilled and unique astrologist. In Genshin Impact, others who practise the craft are in it for the money. However, Mona lives a thrifty life and has vowed to never use astrology for profit. Unfortunately, this vow has led to a constant worry about her financial state.

Our Genshin Impact Mona guide will help you work out which weapons and artifacts to use with this five-star hydro character, as well as give you a rundown on her skills and ascension costs. Mona can be used in either a support or sub DPS role and her ability to dash over water makes her an asset even when exploring.

If you already know everything about Mona, and need some information on other popular characters, take a look at our Genshin Impact Venti and Genshin Impact Albedo guides. We also have a Genshin Impact tier list so you can see where each of your party members rank, and a Genshin Impact codes list, just in case you’re after some extra primogems.

The best Genshin Impact Mona build

As mentioned above, Mona excels in either a support or sub DPS role. We’ve included suitable weapons and artifacts for both choices, so you can choose whichever path you prefer. We recommend pairing her up with a pyro character like Bennett or Diluc in order to trigger vaporize.
