Mona Gameplay
Mona's gameplay centers around her Elemental Burst which applies an Illusory Bubble to enemies that traps them and makes them Wet. When the bubble is broken by damage, it applies the Omen debuff, which increases damage taken by affected enemies. The Omen debuff's duration only begins counting down after the bubble pops, and in Freeze teams, frozen enemies can have their bubbles preserved indefinitely, extending the buff duration significantly.
Her Elemental Skill creates an illusory Phantom that continuously taunts enemies and deals Hydro damage. The Phantom explodes after its duration expires or when destroyed, dealing AoE Hydro damage. The Hold version allows Mona to dash backward before summoning the Phantom, providing defensive utility. Her unique Alternate Sprint, Illusory Torrent, allows her to move rapidly across water surfaces and automatically creates a Phantom after 2 seconds if enemies are nearby.
Her primary strengths include providing one of the strongest damage amplification buffs in the game through Omen, which at Talent Level 10 grants up to 60% DMG Bonus. She offers excellent Hydro application for enabling Freeze and Vaporize reactions, has strong energy generation capabilities, and her A4 Passive converts 20% of her Energy Recharge into Hydro DMG Bonus, allowing her to scale offensively with a support-oriented stat. Her exploration utility is unmatched, with her Alternate Sprint allowing effortless water traversal.
However, she has some notable weaknesses. Her Burst has specific timing requirements to maximize the Omen buff duration, making it technically demanding. The Illusory Bubble mechanic can be confusing for new players, and her damage amplification only applies to enemies affected by Omen. Her Alternate Sprint, while useful for exploration, can sometimes be clunky in combat and drains stamina quickly.
Upcoming Hexerei Buffs (Version 6.2)
In Version 6.2 update, Mona will receive significant buffs through the Hexerei Resonance mechanic after completing Witch's Homework: Of Untested Insight. These buffs activate when paired with at least one other Hexerei character (Durin, Venti, Klee, Albedo, Fischl, Sucrose, or Razor).
The core buff introduces the "Astral Glow of Mercury" mechanic: when Mona's Normal Attacks or Charged Attacks hit enemies, she gains 1 stack of Astral Glow of Mercury lasting 8 seconds, stacking up to 3 times with a maximum of 1 stack gained every 0.1 seconds. When another party member triggers a Vaporize reaction, all Astral Glow of Mercury stacks are consumed, increasing that Vaporize rection's damage by 15% per stack consumed.
Additionally, Mona's Normal and Charged Attacks can now extend the Omen duration on enemies by 2 seconds (up to a maximum of 8 seconds extension), with this effect triggering once every 0.5 seconds. This transforms Mona from a pure burst support into an active enabler who rewards on-field time.
Her constellations also receive significant enhancements in Version 6.2. C1 now also increases the DMG Bonus for all Hydro-related Elemental Reactions by 160% of its original effect, making Electro-Charged, Vaporize, and Frozen reactions significantly stronger. C2 now also increases the party's Elemental Mastery by 80 for 12 seconds after Mona hits an enemy with a Charged Attack, providing valuable team-wide buffs. C4 gains a new secondary effect where Hexerei characters hitting enemies debuffed by Omen deal 15% extra CRIT DMG. C6 now buffs Mona's Charged Attack damage by 200% against enemies debuffed by Omen, dramatically increasing her personal damage potential.
These buffs transform Mona from a one-burst support into a continuous enabler and buffer for reaction-based teams, particularly Vaporize compositions where she can provide up to 30% increased Vaporize damage through Phantasmal Bubble stacks.
Mona Talent Priority
Mona's talent priority heavily focuses on her Elemental Burst, which provides her signature damage amplification buff.
Support/Sub-DPS Talent Priority
| Talent | Priority |
|---|---|
| Elemental Burst | ★ ★ ★ ★ ★ (Highest) |
| Elemental Skill | ★ ★ ★ (Medium) |
| Normal Attack | ★ ★ (Low) |
Elemental Burst - Stellaris Phantasm
Level Mona's Elemental Burst first and ideally to at least Level 8 to maximize the Omen DMG Bonus duration. The Omen debuff is the primary reason to use Mona, providing a massive damage amplification window for your team.
Elemental Skill - Mirror Reflection of Doom
Level Mona's Elemental Skill second as it provides consistent Hydro application and energy generation. The Phantom's periodic Hydro damage helps maintain elemental auras for reactions, and its taunt mechanic provides valuable crowd control.
Normal Attack - Ripple of Fate
Level Mona's Normal Attack last unless running a Main DPS Vaporize build. Her Normal Attack multipliers are relatively standard for Catalyst users, and most builds prioritize her Burst and Skill utility over Normal Attack damage. However, for Charged Attack Vaporize builds, some investment becomes valuable as her Charged Attack has no ICD and can consistently trigger Vaporize reactions.
With the upcoming Version 6.2 buffs, Normal Attacks gain additional value as they generate Phantasmal Bubble stacks and extend Omen duration, making them more relevant for hybrid support/Sub-DPS playstyles.

Mona Best Weapons
Mona's best weapon varies depending on your preferred build and team role. For Support builds, Energy Recharge and team-buffing weapons are ideal. For Sub-DPS and Burst DPS builds, weapons with CRIT stats or ATK% provide better personal damage.

Mona Best Artifacts & Stats
Mona's artifact selection depends heavily on her role in the team and whether you prioritize her support utility or personal damage.
Noblesse Oblige: Best pure support option. Provides team-wide ATK buff on top of Mona's Omen debuff. Most effective when no other party member is using 4-piece Noblesse.
Tenacity of the Millelith: Alternative support set when using TTDS. Mona's Phantom can trigger the 4-piece effect off-field, providing consistent ATK buff uptime. Less reliable than Noblesse due to 3-second duration requiring constant refreshing.
- Emblem of Severed Fate: Best overall option for Sub-DPS builds. Converts Energy Recharge into Burst damage, synergizing perfectly with Mona's A4 Passive that also scales with ER. Easier to farm with good substats due to domain efficiency. Aim for 200-250% Energy Recharge for maximum effectiveness.

Mona Best Team Compositions
Mona's versatility allows her to fit into various team archetypes, with Freeze and Vaporize teams being her strongest options.
1. Freeze Team
Freeze teams are Mona's signature composition where her Omen duration can be extended indefinitely by keeping enemies frozen. The frozen status preserves the Illusory Bubble, preventing the Omen timer from counting down.
| Main DPS | Support | ||
|---|---|---|---|

Vaporize teams mainly utilize use Mona as a Hydro enabler for continuous Vaporize reactions.

Mona Constellations
Mona performs excellently at C0 as a support character, making her constellations luxury upgrades rather than necessities. As a Standard Banner character, constellations are obtained through luck rather than intentional pulling.
C1 Performance
When any of your own party members hits an opponent affected by an Omen, the effects of Hydro-related Elemental Reactions are enhanced for 8s: Electro-Charged DMG increases by 15%. Vaporize DMG increases by 15%. Hydro Swirl DMG increases by 15%. Frozen duration is extended by 15%.
C1 provides valuable utility for reaction-based teams by enhancing all Hydro-related reactions. The 15% damage increase to Vaporize and Electro-Charged reactions benefits the entire team, not just Mona. The extended Freeze duration is particularly valuable in Freeze compositions. With Version 6.2 buffs, C1 also increases the DMG Bonus for Hydro reactions by 160% of its original effect, making it significantly more impactful. This constellation represents good value if obtained.
C2 Performance
When a Normal Attack hits, there is a 20% chance that it will be automatically followed by a Charged Attack. This effect can only occur once every 5s.
C2 is generally considered Mona's weakest constellation for standard support builds since she rarely uses Normal Attacks in typical rotations. The 20% proc chance and 5-second cooldown make it unreliable even for on-field DPS builds. With Version 6.2 buffs, C2 gains additional value by increasing the party's Elemental Mastery by 80 for 12 seconds after hitting enemies with a Charged Attack, providing team-wide utility. This transforms C2 from a weak personal damage boost into a valuable team support constellation.
C4 Performance
When any party member attacks an opponent affected by an Omen, their CRIT Rate is increased by 15%.
C4 is Mona's best constellation and represents an excellent stopping point. The 15% CRIT Rate buff applies to the entire team and works on the damage that pops Mona's Illusory Bubble. In Freeze teams that can extend Omen duration indefinitely, this provides permanent CRIT Rate buff uptime, allowing team members to build more CRIT DMG. This constellation significantly increases team damage without requiring Mona investment. With Version 6.2 buffs, C4 gains a secondary effect where Magic characters hitting Omen-debuffed enemies deal 15% extra CRIT DMG, providing even more damage amplification for Hexenzirkel teams.
C6 Performance
Upon entering Illusory Torrent, Mona gains a 60% increase to the DMG of her next Charged Attack per second of movement. A maximum DMG Bonus of 180% can be achieved in this manner. The effect lasts for no more than 8s.
C6 dramatically increases Mona's personal Charged Attack damage by providing up to 180% DMG Bonus after using her Alternate Sprint for 3 seconds. This constellation transforms Mona into a viable Main DPS option for Vaporize Charged Attack teams. With Version 6.2 buffs, C6 also buffs Charged Attack damage by 200% against enemies debuffed by Omen, providing massive personal damage potential. However, the investment required to reach C6 on a Standard Banner character makes this impractical for most players.
Conclusion
This comprehensive guide demonstrates Mona's position as one of the most versatile and powerful support characters in Genshin Impact. Her Omen debuff provides unmatched damage amplification for burst-oriented teams, while her strong Hydro application enables powerful Freeze and Vaporize compositions. Her A4 Passive's unique Energy Recharge to Hydro DMG conversion allows her to scale offensively while maintaining support capabilities, and her availability on the Standard Banner makes her accessible to all players over time.
With the upcoming Version 6.2 Hexenzirkel buffs, Mona is poised to receive significant enhancements that expand her role from a pure burst support into an active enabler and buffer. The Phantasmal Bubble mechanic rewards on-field time and enables powerful Vaporize amplification, while the ability to extend Omen duration through attacks increases her flexibility. These updates ensure that the renowned astrologist remains relevant and valuable in the evolving meta, particularly in Hexenzirkel team compositions featuring characters like Klee, Durin, and other Magic-type characters.
To fully unlock Mona's potential and enhance your overall team power, consider topping up Genshin Impact resources through reliable top-up services to acquire the in-game currency needed for upgrades, weapons, and essential gear, ensuring that Mona and your other characters are ready for any challenge.
