Mona
Who is Mona?
Mona is a 5★ Hydro Catalyst character from Mondstadt — a distinguished astrologist and student of the art of astrology. She is one of the most flexible supports in the game: her Elemental Burst creates an Omen that amplifies all incoming damage to marked enemies, and her C4 provides a teamwide +15% CRIT Rate during Omen. Excels in Freeze (where Omen duration is extended by Frozen status) and Vaporize nuke setups. Source: keqingmains.com/mona/
