Mona Guide & Best Builds

Welcome to our Mona build guide for Genshin Impact. Mona is a 5-Star Hydro Support Character. Mona's primary goal is to use her Elemental Burst, Stellaris Phantasm, to amplify team damage and create massive elemental reactions. She can also use her Elemental Skill, Mirror Reflection of Doom, to continuously taunt enemies and deal off-field Hydro damage.

Best Artifacts for Mona

Mona's artifact choices are very important for her support value, as they focus heavily on securing enough Energy Recharge. Your main focus should be stacking as much ER as possible.

2-Piece Set: Energy Recharge +20%.

4-Piece Set: If the equipping character has completed Witch's Homework, after they use an Elemental Skill, they also gain "Light's Guidance" for 20s: All nearby party members gain a 20% Elemental DMG Bonus corresponding to the equipping character's Elemental Type. The equipping character can trigger this effect while off-field. DMG Bonuses provided by Artifact Sets with the same name do not stack.\n· When your party has the Hexerei: Secret Rite effect, Light's Guidance is upgraded to "Mortal Hymn": All nearby party members gain a 40% Elemental DMG Bonus corresponding to both the equipping character and the current active party member's Elemental Type instead. If both characters have the same Elemental Type, these bonuses will not stack.

Mona's Stat Priority

: Energy Recharge

: ATK %

: CRIT Rate / CRIT DMG

Substats: Energy Recharge > CRIT Rate / CRIT DMG

Your Energy Recharge needs are extremely high for Mona. You must aim for enough ER to guarantee quick rotations so you can chain Elemental Reactions together. Once your Energy needs are met, stack CRIT stats to increase the damage of reactions triggered with her Hydro application.

Recommended Stats for Mona

Listed below are our recommended stats for Mona. Build recommendations assume a strict Support/Burst role for Mona.

Mona's Talent Priority

Mona's Elemental Burst is the core of her support playstyle, as it provides her massive Omen damage buff, making it your highest priority. Her Elemental Skill should be leveled next for its taunt and off-field damage. Normal Attacks can be left unleveled.

How to Play Mona

Mona supports a Main DPS by using her Elemental Burst, Stellaris Phantasm, to apply Omen through the Illusory Bubble she creates. This gives you precise control over when to trigger the damage amplification window. Her Burst ability has three main components:

1. Applies Hydro to enemies.
2. Creates the Illusory Bubble.
3. Applies Omen when the Illusory Bubble is broken.

Understanding these three components will help you set up huge Elemental Reactions to take down bosses with ease. The Omen buff does have a timer on it, so be aware of what order you are doing your rotations in. You want your Main DPS to activate the buff, then continue to play on-field to take full advantage of the damage amplification.

Between Burst casts, use her Elemental Skill, Mirror Reflection of Doom, to create an Illusion that continuously taunts enemies and deals Hydro damage. Be mindful that it only lasts 5 seconds, so it can be difficult to complete a full team rotation before it ends.

Mona's Best Constellations

Almost all of Mona's constellations are useful and amplify her ability to buff a Main DPS. However, Mona functions perfectly at C0 without any issues. Typically, you want to aim for her max constellation (C6), but since she does not have her own limited banner, this happens naturally over time by losing 50/50s.

Prophecy of Submersion (C1) is a fantastic support constellation. When any party member hits an opponent affected by an Omen, the effects of Hydro-related Elemental Reactions (like Vaporize or Freeze) are enhanced for 8 seconds.

Prophecy of Oblivion (C4) provides another excellent team buff, increasing the CRIT Rate of any party member attacking an opponent affected by an Omen by 15%.
