Who Is Mona in Genshin Impact?

Mona Megistus — formally titled Astrologist Mona Megistus — is a 5-star Hydro Catalyst character from Mondstadt in Genshin Impact. She is one of the original characters available since the game’s launch in September 2020 and appears on the Standard Banner permanently, making her obtainable by all players over time. Her constellation is Astrolabos.

Lore-wise, Mona is an exceptionally gifted astrologist of great skill and equally great pride. She has taken up residence in Mondstadt to escape the wrath of her master after she accidentally read the latter’s diary — an event she now carefully avoids discussing. Despite her talents, Mona lives perpetually broke, having spent every mora she earns on research materials and star charts. She is a member of the Hexenzirkel, an ancient assembly of witches to which Alice (Klee’s mother) also belongs, and recent updates to her kit have incorporated her Hexenzirkel identity into her abilities.

In combat, Mona is one of the most powerful burst-window amplifiers in the game. Her Elemental Burst applies a debuff called Omen that increases all DMG the team deals to marked enemies by a significant percentage. Combined with Freeze to immobilize enemies, or with Vaporize reactions in quickswap compositions, her Omen buff enables some of the highest single-rotation damage outputs in the entire game. You can play her on Android, iOS, PlayStation, Epic Games, and Xbox.

If you are building teams around Mona, check out the Kamisato Ayaka character guide and the Ganyu character guide — both are top-tier Cryo DPS characters who thrive in Mona’s Freeze team setups.

Mona Skills and Abilities

Normal Attack – Ripple of Fate

Mona performs up to 4 water splash attacks that deal Hydro DMG. Her Charged Attack consumes stamina and deals AoE Hydro DMG after a short casting time. She also has a Plunging Attack. In support builds, these are rarely used in combat. However, in Hexerei builds (see passives below) and at C6, Normal and Charged Attacks gain additional functionality and damage.

Alternate Sprint – Illusory Torrent

One of Mona’s most distinctive features is her unique alternative sprint. Instead of the standard dash, Mona cloaks herself within water’s flow, consuming Stamina to move at high speed. While sprinting this way she is untargetable by most enemy attacks. Crucially, Mona can also move at high speed across the surface of water while using this sprint — she effectively water-walks, making her one of the best exploration characters for water-heavy areas. When she reappears after the sprint, she applies the Wet status (Hydro) to nearby opponents.

Elemental Skill – Mirror Reflection of Doom

Mona creates an illusory Phantom of Fate from coalesced waterspouts. This Phantom continuously taunts nearby enemies — drawing their attacks away from the party — and deals Hydro DMG at intervals. When the Phantom’s duration expires, it explodes dealing AoE Hydro DMG. Only one Phantom can exist at a time. Using the Skill with a Hold input causes Mona to first move backward swiftly, then conjure the Phantom at her new position.

The Phantom serves two purposes: it applies Hydro to enemies for reaction setups, and it taunts enemies to create breathing room for the team. In many support rotations, the Skill is used primarily to generate Energy for the Burst and to apply Hydro for reactions.

Elemental Burst – Stellaris Phantasm

This is Mona’s signature ability and the reason she is used in most teams. Stellaris Phantasm summons sparkling waves and creates a reflection of the starry sky, applying Illusory Bubble status to all enemies in a large AoE. Illusory Bubble:

• Traps weaker opponents in place, making them temporarily immobile.
• Makes enemies Wet (applies Hydro aura).
• When an enemy affected by Illusory Bubble takes DMG, the bubble pops and applies Omen to that enemy.

Omen is Mona’s key mechanic. While an enemy is under Omen:

• All DMG dealt to that enemy is increased by a substantial percentage that scales with Burst talent level (ranging from roughly 42% at Level 1 to 60% at Level 13).
• Omen lasts for several seconds after the bubble pops.
• The first hit that pops the bubble also benefits from the Omen buff, even though it’s the hit that triggered it.

The standard rotation for Mona teams is to use her Skill and Burst, then immediately have the DPS character deal their main damage while Omen is active. The goal is to stack every buff and reaction bonus on top of the Omen window — this is what creates the massive single-rotation damage numbers Mona is famous for.

Mona Passive Talents

A1 Passive – Come ‘n’ Get Me, Hag!

After Mona has been in Illusory Torrent (her alternate sprint) for 2 seconds, if there are enemies nearby, she will automatically create a Phantom of Fate. This auto-generated Phantom lasts 2 seconds and its explosion DMG is equal to 50% of Mirror Reflection of Doom’s explosion damage. This passive provides a free Hydro application and a bit of free damage during her sprint movement, without needing to manually use the Skill. It is particularly useful for applying Hydro before she uses her Burst.

A4 Passive – Waterborne Destiny

This is Mona’s most important personal damage passive. It increases her Hydro DMG Bonus by an amount equal to 20% of her Energy Recharge rate. Since Mona stacks large amounts of ER (often 200–300%), this passive converts that ER directly into Hydro DMG Bonus. For example, at 250% ER, she gains 50% Hydro DMG Bonus from this passive alone. This is why building ER on Mona is doubly rewarding — it both ensures Burst uptime and simultaneously boosts her personal damage output significantly.

Utility Passive – Principium of Astrology

When Mona crafts Weapon Ascension Materials at the Blacksmith, she has a 25% chance to refund one count of one of the crafting materials used. This is a helpful crafting passive for players who need to forge Weapon Ascension Materials regularly — it can save a meaningful amount of ore over time.

Hexenzirkel Passive – Witch’s Eve Rite

This passive activates after completing the quest Witch’s Homework: Of Untested Insight, which makes Mona a Hexerei character. When the party includes at least 2 Hexerei characters, the team gains the Hexerei: Secret Rite effect, which enhances Hexerei characters’ abilities. For Mona specifically, when her Normal or Charged Attacks hit an opponent, she gains 1 stack of Astral Glow of Mercury (up to 3 stacks, lasting 8 seconds). When other party members trigger a Vaporize reaction on an enemy, all stacks are consumed — each stack consumed increases the damage of that Vaporize reaction. This passive adds a new Vaporize amplification role to Mona in Hexerei team compositions with characters like Klee or Jean.

Mona Constellations Guide

Mona’s constellations meaningfully improve her team support value. C1 and C4 are the strongest picks for team buff-focused builds.

C1 – Prophecy of Submersion

When any of your party members hits an opponent affected by Omen, the effects of Hydro-related Elemental Reactions are enhanced for 8 seconds:

• Electro-Charged DMG increases by 15%.
• Vaporize DMG increases by 15%.
• Hydro Swirl DMG increases by 15%.
• Frozen duration is extended by 15%.

Additionally, when off-field party members trigger these reactions, the bonuses are enhanced to 160% of the above values. C1 is an excellent constellation for Freeze and Vaporize teams. The 15% Vaporize DMG bonus stacks directly on top of the Omen buff for huge combined amplification. The extended Freeze duration is particularly valuable in Freeze compositions, giving the DPS more time to deal damage to frozen enemies without them breaking free.

C2 – Lunar Chain

When Mona’s Normal Attack hits an enemy, there is a 20% chance that it will be automatically followed by a Charged Attack. This can only occur once every 5 seconds. Additionally, within 5 seconds after using Stellaris Phantasm, her first Normal Attack that hits an enemy will automatically trigger a Charged Attack. This constellation is primarily for DPS or Hexerei-focused Mona builds and has limited value in standard support builds where Mona’s Normal Attacks are rarely used.

C3 – Restless Revolution

Increases the Level of Stellaris Phantasm (Elemental Burst) by 3, up to a maximum of Level 15. A direct boost to her Burst damage and the Omen DMG% buff percentage, which meaningfully increases team DPS output.

C4 – Prophecy of Oblivion

When any party member attacks an opponent affected by Omen, their CRIT Rate is increased by 15%. When any Hexerei party member attacks an opponent affected by Omen, their CRIT DMG is also increased by 15%. C4 is Mona’s second-best constellation. A flat 15% CRIT Rate for the entire team during the Omen window is an extremely powerful universal buff. For a Cryo DPS like Ayaka who already has high CRIT Rate, this can push them to soft-cap territory without needing CRIT Rate substats. For any DPS, 15% extra CRIT Rate during the burst window directly translates to more CRIT hits and higher average damage.

C5 – Mockery of Fortuna

Increases the Level of Mirror Reflection of Doom (Elemental Skill) by 3, up to a maximum of Level 15. Boosts the Hydro DMG and DoT of her Phantom. Less impactful than C3 or C4 for team support purposes.

C6 – Rhetorics of Calamitas

While Mona is the active character, while she is in Illusory Torrent or when there are opponents affected by Omen nearby, she gains a 60% increase to the DMG of her next Charged Attack per second of this state’s duration. A maximum bonus of 180% can be achieved. This effect lasts up to 8 seconds. Additionally, the DMG Mona’s Charged Attacks deal to opponents affected by Omen is increased to 200% of the original DMG. C6 transforms Mona into a capable on-field Charged Attack DPS with massive burst-window damage potential, especially in Hexerei Vaporize teams. However, it requires significant on-field time that many team rotations cannot accommodate for a support-focused role.

Mona Best Build – Artifacts

Mona’s artifact build revolves around one core principle: stack Energy Recharge first. Her A4 passive converts ER into Hydro DMG Bonus, so every ER substat serves double duty. After hitting her ER threshold, invest in CRIT stats for personal damage output.

Best Artifact Set – 4-Piece Emblem of Severed Fate (Personal Damage Build)

This is Mona’s best set for maximizing both her Burst damage and her ER stacking simultaneously. The 2-piece gives 20% ER, and the 4-piece converts a portion of ER into Elemental Burst DMG Bonus (up to 75% bonus from ER). Since Mona builds high ER naturally, the Emblem set converts that ER into massive Burst damage on top of her A4’s Hydro DMG Bonus conversion. This set rewards investing in ER from every angle — the more ER she has, the better both the 4-piece bonus and her A4 passive perform together. Farm this set from the Momiji-Dyed Court domain in Inazuma.

Best Artifact Set – 4-Piece Noblesse Oblige (Team Support Build)

For players who want to focus purely on team buffing rather than Mona’s personal damage, 4-piece Noblesse Oblige is the choice. Its 4-piece bonus increases all party members’ ATK by 20% for 12 seconds after using the Elemental Burst. Since Mona uses her Burst every rotation, this buff has excellent uptime and applies to every ATK-scaling DPS on the team. Always confirm no other team member is already wearing Noblesse — only one instance of the 4-piece bonus applies per team. This set is farmed from the Clear Pool and Mountain Cavern domain in Liyue.

Alternative – 4-Piece Tenacity of the Millelith

The Phantom from Mona’s Elemental Skill continuously deals hits, which can trigger the 4-piece Tenacity of the Millelith effect (increases all party members’ ATK by 20% and shield strength by 30% for 3 seconds when off-field Skill damage hits an enemy). With good Phantom uptime this ATK buff can be fairly consistent. Use this when both Noblesse Oblige and Emblem are already occupied by other teammates.

Artifact Main Stats

• Sands: Energy Recharge% (primary) or ATK% once ER threshold is met
• Goblet: Hydro DMG Bonus (for personal damage builds) or ATK% (if ER is very high and you have Emblem, where the extra ER from Sands converts well)
• Circlet: CRIT Rate or CRIT DMG

Artifact Substats Priority

Energy Recharge > CRIT Rate / CRIT DMG > ATK%. Target 180–250% Energy Recharge in most teams. With another Hydro character generating particles, she can get away with less ER. Without additional Hydro support, push toward 250%+ to ensure her Burst is ready every rotation. After hitting the ER threshold, CRIT Rate and CRIT DMG become the priority for maximizing her personal Burst damage and Charged Attack output.

Mona Best Weapons

1. Thrilling Tales of Dragon Slayers (3-Star) – Best F2P Support Weapon

Do not be fooled by this weapon’s low rarity. At R5, it grants the next character who takes the field after Mona a +48% ATK buff for 10 seconds. For ATK-scaling DPS characters, this is an enormous and essentially free buff that easily outperforms many 4-star and even 5-star options for team DPS increase. It has no substat and provides no benefit to Mona personally, but when used as a pure team buffer tool it is exceptional. Use this when Mona already has enough ER from artifacts and the team’s DPS scales on ATK.

2. The Widsith (4-Star) – Best 4-Star Personal Damage Weapon

The Widsith has a CRIT DMG substat and a passive that randomly grants one of three buffs when the character takes the field: 120% ATK bonus, 96% Elemental DMG bonus, or 480 Elemental Mastery. Two of these three buffs (ATK and Elemental DMG) directly amplify Mona’s Burst damage during her on-field window. It is her best 4-star damage weapon and works well in burst-window compositions where she is on-field briefly to use her Skill and Burst before swapping off.

3. Favonius Codex (4-Star) – Best Team Energy Weapon

Provides Energy Recharge and generates additional Elemental Particles on CRIT hits. Favonius Codex is the best choice when the team needs more Energy support — the extra particles generated can help fund the Bursts of other energy-hungry teammates. A CRIT Rate Circlet helps trigger the passive reliably. A good all-purpose choice that solves Mona’s ER needs while also giving back to the team.

4. Skyward Atlas (5-Star)

Provides ATK% and an Elemental DMG Bonus passive that also can deal periodic DMG to enemies. The ATK% substat helps Mona’s Burst deal more damage, and the passive Elemental DMG bonus is a consistent buff. A solid premium option if available. Works best in Mona builds where personal Burst damage is prioritized alongside support value.

5. Memory of Dust (5-Star)

Provides ATK% and a passive that stacks ATK after creating a shield or triggering Mona’s various effects. In teams with Zhongli for shielding, Memory of Dust’s ATK stacks become reliable. It pairs particularly well with Mona in specific Vaporize compositions where both ATK and the passive DMG% from shields contribute. The passive also grants additional team DMG bonus when the equipped character’s Hexerei passive is active.

6. Prototype Amber (4-Star, Craftable)

A craftable Catalyst that provides HP% and restores Energy for the team after using the Burst. While HP% is not a priority stat for Mona, the Energy restoration passive can offset some of her ER requirements and help other team members recharge their Bursts faster. A budget support option if you lack the other weapons listed above.

Mona Best Teams

Mona’s strongest role is in burst-window teams — compositions where most or all of the team’s damage is concentrated in a short window right after her Omen is applied. She is best paired with characters who deal the majority of their damage in a single rotation rather than over extended periods. For more context on the DPS characters who pair with her best, read the Kamisato Ayaka guide, Ganyu guide, and Hu Tao guide.

Ayaka Freeze Team – Best Overall Team

• Main DPS: Kamisato Ayaka
• Buffer: Mona
• Cryo Support: Shenhe
• Anemo Support: Kaedehara Kazuha or Venti

This is one of the strongest and most iconic team compositions in Genshin Impact. Mona applies Hydro for Freeze, traps enemies in place with Illusory Bubble, applies Omen for a massive DMG% buff, and Ayaka then deals enormous AoE Cryo DMG to frozen enemies during the Omen window. Shenhe boosts Cryo DMG further with her Cryo DMG bonus and RES shred. Kazuha or Venti provide Cryo RES shred via Viridescent Venerer and crowd control. At C1 Mona, the extended Freeze duration ensures enemies stay immobilized through Ayaka’s entire damage window. At C4 Mona, the 15% CRIT Rate buff makes Ayaka’s damage even more consistent.

Ganyu Freeze Team

• Main DPS: Ganyu
• Buffer: Mona
• Cryo Support: Diona (shields + healing + Cryo resonance)
• Anemo Support: Venti

Ganyu’s Charged Attacks deal massive Cryo DMG and benefit enormously from both Omen’s DMG% buff and Freeze immobilization. Mona applies Hydro to Freeze enemies while also amplifying their damage vulnerability. Diona provides shields and healing with Cryo resonance. Venti groups enemies and shreds Cryo RES through Viridescent Venerer. This is one of the highest single-rotation damage compositions in the game.

Hu Tao Vaporize Quickswap Team

• Main DPS: Hu Tao
• Buffer: Mona
• Anemo Support: Kaedehara Kazuha
• Healer: Zhongli or Bennett

Mona applies Hydro aura to enemies before Hu Tao’s Pyro-infused attacks trigger Vaporize for 1.5x DMG amplification. Omen’s DMG% buff stacks on top of the Vaporize multiplier, creating enormous burst damage during Hu Tao’s Burst window. At C1 Mona, the extra 15% Vaporize DMG stacks further. Kazuha provides Hydro or Pyro RES shred and crowd control. Note: Mona is not ideal for extended Hu Tao rotations since she can over-apply Hydro and prevent Hu Tao’s Pyro from triggering Vaporize reliably — use her specifically for burst windows.

Hexenzirkel Vaporize Team

• On-Field DPS: Klee (Hexerei character)
• Buffer: Mona (Hexerei character)
• Support: Jean or another Hexerei character
• Flex: Bennett

With at least two Hexerei characters in the party, Mona’s Hexenzirkel passive activates. Her Astral Glow of Mercury stacks build through Normal and Charged Attacks, and when Klee triggers Vaporize on an enemy, all stacks are consumed to amplify that reaction’s damage. This team plays more on-field than Mona’s typical style and rewards chaining her attacks with Klee’s Pyro for boosted Vaporize bursts. The Hexerei passive adds a new dimension to both characters’ kits.

Tartaglia (Childe) Vaporize Team

• Main DPS: Tartaglia
• Sub-DPS / Buffer: Mona
• ATK Buffer: Bennett
• Pyro Sub-DPS: Xiangling

In this team Mona provides a brief Hydro aura and Omen buff before Childe takes the field. Xiangling’s Pyronado then creates Vaporize reactions on the Hydro-affected enemies. Mona’s role is primarily to buffer, with the TTDS weapon handing off an ATK buff to the DPS after she swaps. Bennett provides healing and the massive ATK field bonus from his Burst.

Mona Ascension Materials

Here is the complete list of everything needed to fully ascend Mona to Level 90:

Mona Ascension Materials List

• Varunada Lazurite Sliver x1
• Varunada Lazurite Fragment x9
• Varunada Lazurite Chunk x9
• Varunada Lazurite Gemstone x6
• Philanemo Mushroom x168 (Local Specialty)
• Cleansing Heart x46 (Boss Drop)
• Whopperflower Nectar x18
• Shimmering Nectar x30
• Energy Nectar x36
• 420,000 Mora

Where to Get Mona’s Ascension Materials

Philanemo Mushroom is Mona’s Mondstadt local specialty. These mushrooms grow on the walls and rooftops of buildings in Mondstadt City, Springvale, and near the Dawn Winery. They are one of the most accessible local specialties in the game — large clusters grow on the sides of houses and can be spotted easily with their distinctive purple-pink color. If Klee is in your party, her passive talent reveals nearby Philanemo Mushrooms on the mini-map automatically. Respawn every 48 hours.

Cleansing Heart is dropped by the Oceanid, a world boss found east of Qingce Village in Liyue (near the Bishui Plains). The Oceanid is a Hydro boss that fights exclusively by summoning Hydro mimics of birds, crabs, squirrels, and other animals. Since it is a Hydro boss, avoid bringing Hydro characters — use Cryo, Electro, or Pyro characters to deal with the mimics effectively. The Oceanid also drops Varunada Lazurite, making it the most efficient single boss to farm for both of Mona’s main ascension materials simultaneously.

Whopperflower Nectars (Whopperflower Nectar, Shimmering Nectar, Energy Nectar) are dropped by Whopperflower enemies found all across Teyvat in Pyro, Cryo, and Electro variants. They are among the most common enemies in the game. All three types drop the same nectar tiers — higher tiers drop from higher-level Whopperflowers.

Varunada Lazurite gems for Hydro characters can be obtained from the Oceanid, the Hydro Hypostasis, the Hydro Tulpa in Fontaine, and several other Hydro-affiliated bosses. Use Dust of Azoth at the Alchemy Bench to convert other gem types if needed.

Mona Talent Materials

Here is the complete list needed to fully upgrade all three of Mona’s talents to Level 10:

Mona Talent Materials List

• Teachings of Resistance x9
• Guide to Resistance x63
• Philosophies of Resistance x114
• Ring of Boreas x18 (Weekly Boss Drop)
• Whopperflower Nectar x18
• Shimmering Nectar x66
• Energy Nectar x93
• Crown of Insight x3 (to fully crown all 3 talents)

Where to Get Mona’s Talent Materials

Resistance Talent Books (Teachings, Guide, and Philosophies of Resistance) are obtained from the Forsaken Rift Domain in Mondstadt. This domain is open on Wednesdays, Saturdays, and Sundays only. She shares this talent book series with Fischl and Razor — farming alongside them is efficient. Be aware that this domain contains Cryo enemies, so bring Pyro characters to deal with them.

Ring of Boreas is Mona’s weekly boss drop. It is obtained by defeating Andrius, Dominator of Wolves (the Wolf of the North) in the Wolf of the North Challenge domain in Wolvendom, Mondstadt. This is one of the oldest weekly bosses in the game and is very accessible. Andrius deals Cryo and Anemo DMG — bring characters that are not weak to these elements. He cannot be shielded against in the standard sense, so healing or resistance matters more. He can be challenged in co-op, making it easy to clear with friends if needed. Dream Solvents can convert other Andrius drops into Ring of Boreas.

Mona Talent Upgrade Priority

• 1st Priority: Elemental Burst – Stellaris Phantasm. The Omen’s DMG% buff percentage scales directly with Burst talent level — higher talent level means a bigger team-wide damage amplification window. Always max this first.
• 2nd Priority: Normal Attack – Ripple of Fate. This controls the scaling of her Charged Attack, which becomes relevant in Hexerei and C6 builds. In standard support builds this is the lowest priority, but the Charged Attack’s damage can be significant in the right team setup.
• 3rd Priority: Elemental Skill – Mirror Reflection of Doom. The Phantom’s damage is a small fraction of total team output in most rotations. Level this last for standard support builds. In DPS or Hexerei builds it has more value.

How to Get Full Value from Mona’s Omen

Getting maximum damage from Mona’s Omen buff requires careful timing and rotation planning:

• Use Mona’s Skill first to generate Energy and apply Hydro to enemies.
• Use her Burst — this applies Illusory Bubble to all enemies. Do not hit enemies yet if possible.
• Set up other team buffs while the Bubble is intact: use Bennett’s Burst, Kazuha’s Skill, Shenhe’s Skill — any ATK or DMG buffs from other teammates.
• Then have the DPS land their first hit. This pops the Bubble, activates Omen instantly (the popping hit itself benefits from Omen), and starts the Omen timer.
• Continue the DPS’s rotation entirely within the Omen window.

The most common mistake is accidentally popping the Bubble before all buffs are in place, or having a support character’s follow-up attack pop it too early. Plan the rotation to pop Omen at the exact moment the DPS’s biggest hits are about to land.

Mona as an Exploration Character

Mona’s alternate sprint (Illusory Torrent) makes her one of the most useful exploration characters in the game. She moves at very high speed without being targetable, which means she can rush through dangerous areas safely. More importantly, she can sprint across the surface of water — turning any body of water into a traversable surface without spending Stamina on swimming. In regions like Fontaine with extensive underwater and surface water areas, or in coastal exploration, Mona’s water-walking sprint saves enormous amounts of time and Stamina. Her A1 passive also auto-creates Phantoms to distract enemies while she is sprinting, which can buy time when moving through enemy territories.

Mona Pros and Cons

Pros

• Omen’s DMG% amplification buff applies universally to all damage types — one of the most efficient damage multipliers in the game for burst-window compositions.
• Combines Hydro application, enemy taunting, crowd control (via Illusory Bubble), and DMG amplification all in one kit.
• A4 passive’s ER-to-Hydro DMG conversion makes stacking ER doubly efficient for both Burst uptime and personal damage.
• Water-walking sprint makes her one of the best exploration characters in the game.
• Available on the Standard Banner — all players can obtain her over time without needing a specific event banner.
• Very quick rotation — uses Skill and Burst, then swaps off. Minimal field time requirements.
• Strong constellations: C1 extends Freeze and boosts Vaporize; C4 grants the whole team 15% CRIT Rate during Omen.

Cons

• Omen’s effectiveness depends heavily on timing — if the DPS cannot concentrate damage in the short Omen window, much of its value is wasted.
• High Energy Recharge requirements (180–250%) can be challenging to reach alongside CRIT stats.
• Does not provide healing, shields, or sustained off-field DPS — purely a burst-window amplifier and Hydro applicator.
• Illusory Bubble popping mechanic can be frustrating — off-field character hits or stray attacks can pop it before the DPS is ready, wasting the amplification window.
• Outclassed by Furina in many modern team compositions for sustained Hydro support and team buffing over long fights.
• Weak in sustained damage compositions where fights last longer than her Omen window.

Tips for Playing Mona

• Stack ER aggressively before other stats: 200% ER at minimum. With the Emblem set, Favonius Codex, and ER substats you can hit this while still having room for CRIT stats. Mona is unplayable if she cannot use her Burst every rotation.
• Control when the Bubble pops: After using her Burst, the Illusory Bubble stays until something hits the enemy. Avoid having off-field characters with auto-attacks hit enemies during this setup window. Time the first DPS hit intentionally.
• Layer buffs before popping: Use Bennett’s Burst, Kazuha’s Skill, Shenhe’s Skill, and any other pre-buff actions before popping the Bubble. Stack every multiplicative buff you have before the DPS starts attacking, then pop Omen and go.
• Use Thrilling Tales when ER is handled: Once Mona has enough ER from artifacts and substats alone, equip TTDS for the free 48% ATK buff transferred to the DPS when you swap. This is one of the highest-value support actions a single item can provide in the game.
• Sprint across water for exploration: Never swim across open water if Mona is in your party. Her alternate sprint is faster than swimming and does not consume Stamina for water movement — keep her in your exploration party whenever exploring coastal or aquatic areas.
• In Freeze teams, pop Omen with a Cryo hit: Having the Cryo DPS land their first hit pop the Bubble means it immediately freezes the enemy (Cryo + Hydro from the bubble pop). The frozen enemy cannot move and takes the full Omen DMG buff during the DPS’s entire rotation. This is the correct execution for Ayaka and Ganyu teams.

Is Mona Worth Building?

Yes — Mona remains one of the best supports for specific team archetypes, especially Freeze teams and Vaporize nuke setups. Her Omen buff is still one of the highest DMG% amplifications available in a single support slot, and her combination of Hydro application, crowd control, and team buffing makes her a genuine powerhouse in burst-window compositions.

While she has been partially surpassed by newer Hydro characters like Furina and Yelan in sustained fight compositions, Mona remains the best choice for Freeze nuke teams built around Kamisato Ayaka or Ganyu, and her Omen + Vaporize interaction is still extremely powerful for quickswap burst builds. Being permanently on the Standard Banner means that with enough wishes over time, every player can eventually build her and her constellations. She is especially worth building for players who love Freeze team gameplay, for whom she is essentially irreplaceable at C1 and above. For other strong Hydro supports to compare, also look at Xingqiu, Sangonomiya Kokomi, and Barbara.
