Normal Attack: Perform up to 4 water splash attacks that deal Hydro DMG.

Charged Attack: Consumes a certain amount of Stamina to deal AoE Hydro DMG after a short casting time.
Plunging Attack: Gathering the might of Hydro, Mona plunges towards the ground from mid-air, damaging all opponents in her path. Deals AoE Hydro DMG upon impact with the ground.

Talent Stellaris Phantasm.pngStellaris PhantasmElemental Burst
Mona summons the sparkling waves and creates a reflection of the starry sky, applying the Illusory Bubble status to the opponents in a large AoE.

Illusory Bubble: Traps opponents inside a pocket of destiny and also makes them Wet. Renders weaker opponents immobile. When an opponent affected by Illusory Bubble sustains DMG, it has the following effects:

  • Applies an Omen to the opponent, which gives a DMG Bonus, also increasing the DMG of the attack that causes it.
  • Removes the Illusory Bubble, dealing Hydro DMG in the process.

Omen: During its duration, increases DMG taken by opponents.

  • Illusory Bubble and Omen are both applied upon casting Stellaris Phantasm.
  • Visible marking: When Illusory Bubble is active on an enemy, there is a constellation-like marking on that enemy. When Omen is active on an enemy, there is a starry purple aura around that enemy.
  • Hydro application: Stellaris Phantasm applies Wet twice: once when cast, and once when the Illusory Bubble bursts.
    • It does no damage upon casting.
    • The application of Hydro causes normal Hydro-related reactions if enemy is already affected by another element, but damage isn't applied until the bubble is popped.
  • Illusory Bubble immobilization: Enemies that can be rendered immobilized by this talent scales with its level.
  • Illusory Bubble bursting: When an enemy is affected by Illusory Bubble, most damage to that enemy will cause the bubble to burst.
    • Damage that does not cause poise damage will not burst the bubble. For example:
      • Resonance from Geo Constructs and hits to shielded or Frozen enemies will not burst the bubble.
      • Xingqiu's Elemental Burst, which does no damage when cast, can burst the bubble because its knockback deals poise damage.
    • If no outside source bursts the bubble, it automatically bursts after 8 seconds.
  • Illusory Bubble vaporization: Maximizing Illusory Bubble's damage with Vaporize:
    • Apply Pyro to the enemy (e.g. using Bennett's Elemental Burst)
    • Cast this skill to apply Hydro, resulting in Vaporize and clearing both elemental statuses (also, it deals no damage at this point)
    • Wait for 2 seconds for the Internal Cooldown of Mona's burst Hydro application
    • Switch to a Pyro damage dealer (e.g. Bennett) and do a Pyro attack. This will first apply Pyro on the target, then it will burst the Illusory Bubble, which deals Hydro damage and will react with Pyro to cause Vaporize again, this time dealing massive damage.
  • Omen duration: Omen status timer only starts after the bubble bursts. Since Omen is applied from the initial cast of the skill, if the bubble lasts for its whole duration (8s), Omen can have a maximum duration of 8 + 5 = 13s.
  • Omen damage bonus: Omen grants a damage bonus (maximum 60%) to any attack on the enemy affected by this status.
    • As in any other bonus damage in game, "increase DMG taken by opponents" is additive to other damage bonus source (such as the Normal Attack bonus from Gladiator's Finale 4-piece effect, or Physical/Elemental damage modifiers on artifacts)
    • Because of this, the effective damage modifier of Omen is around 1.15× - 1.2× at endgame, and not 1.6×.

Talent Illusory Torrent.pngIllusory TorrentAlternate Sprint
Alternate Sprint: Mona cloaks herself within the water's flow, consuming stamina to move rapidly.

When under the effect of Illusory Torrent, Mona can move at high speed on water.
Applies the Wet status to nearby opponents when she reappears.

  • In the Spiral Abyss, before starting the challenge, Mona will sprint regularly without cloaking herself with water. But after starting the challenge, she will use her alternate sprint and cloak herself in water.
  • One can hold the sprint button while stationary to make Mona stay in place while cloaking herself in water.
Talent Come 'n' Get Me, Hag!.pngCome 'n' Get Me, Hag!1st Ascension Passive
After she has used Illusory Torrent for 2s, if there are any opponents nearby, Mona will automatically create a Phantom.

A Phantom created in this manner lasts for 2s, and its explosion DMG is equal to 50% of Mirror Reflection of Doom.

Talent Waterborne Destiny.pngWaterborne Destiny4th Ascension Passive
Increases Mona's Hydro DMG Bonus by a degree equivalent to 20% of her Energy Recharge rate.
Talent Principium of Astrology.pngPrincipium of AstrologyUtility Passive
When Mona crafts Weapon Ascension Materials, she has a 25% chance to refund one count of one material out of all the crafting materials used.
  • When used once, it increases the material yield relative to the weapon ascension material being crafted by 8.3%.
  • But if one continuously re-uses these refunded materials, then the total expected gain is around 9% (this involves summing a geometric series; see Alchemy#Derivations).
