Stellaris Phantasm
Elemental Burst
  • Description
  • Gameplay Notes
  • Advanced Properties
  • Attribute Scaling
  • Preview
Mona summons the sparkling waves and creates a reflection of the starry sky, applying the Illusory Bubble status to 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.
  • 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.
  • Stellaris Phantasm is able to apply Wet up to twice: once when cast, and once when the Illusory Bubble bursts. However, standard ICD applies for the two applications.
  • If no outside source bursts the bubble, it automatically bursts after 8 seconds.
  • 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 13s.
  • Illusory Bubble bursts when the affected target is hit by an attack that deals more than 0 Poise Damage. This means that attacks that deal no damage but do deal Poise Damage (e.g. Hu Tao's Elemental Skill activation) will burst the bubble, while hits that deal no Poise Damage will not burst it.
    • This mechanic can be used as a means to extend the effective duration of Omen, such as when combined with the Frozen Elemental Reaction: Frozen targets are immune to Poise Damage, so any attacks against them will not burst the Illusory Bubble until they unfreeze. As a result, the start of Omen's duration countdown is delayed while characters attacking the Frozen target still benefit from the DMG Bonus.
  • Illusory Bubble Explosion DMG does not snapshot and will be affected by changes in Mona's stats after Stellaris Phantasm is cast.
  • The DMG Bonus is additive to other sources of DMG Bonus, such as Mona's 4th Ascension Passive passive, Waterborne Destiny.
  • The Illusory Bubble applies a Struggle state to enemies whose weight is less than or equal to 100, preventing them from performing any actions. However, the Struggle state will not be applied to enemies more than 20 levels higher than Mona.
Constellation Effects
  • Constellation Level 1, Prophecy of Submersion Prophecy of Submersion: increases Electro-Charged DMG, Lunar-Charged DMG, Vaporize DMG, Hydro Swirl DMG, and Frozen duration by 15% when any of the player's own party members hits an opponent affected by Omen.
  • Constellation Level 3, Restless Revolution Restless Revolution: Increases this talent's level by 3, up to a maximum of 15.
  • Constellation Level 4, Prophecy of Oblivion Prophecy of Oblivion: "When any party member attacks an opponent affected by an Omen, their CRIT Rate is increased by 15%."

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. After starting the challenge, her Alternate Sprint will be enabled again.
  • One can hold the sprint button while stationary to make Mona stay in place while cloaking herself in water. No stamina is consumed while Mona is stationary.
  • Despite the appearance of this talent in action, it does not make Mona invisible to enemies, nor does it make her shorter.

"Come 'n' Get Me, Hag!"
1st Ascension Passive
  • Description
  • Gameplay Notes
  • Advanced Properties

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.

  • A Phantom can be created even if Mona is not close enough to attack an enemy, as long as Mona is in combat.
  • No Phantom is created near the Unusual Hilichurl until it is aggravated.
  • Using Illusory Torrent outside of combat counts toward the 2-second timer, although no Phantom will be created until Mona enters combat.
  • Remaining stationary while using Illusory Torrent counts toward the 2-second timer.
  • The 2-second timer resets when Mona stops using Illusory Torrent or when a Phantom is created from "Come 'n' Get Me, Hag!"
  • A Phantom created from "Come 'n' Get Me, Hag!" can exist at the same time as a Phantom from Mirror Reflection of Doom.

4th Ascension Passive
  • Description
  • Gameplay Notes

Increases Mona's Hydro DMG Bonus by a degree equivalent to 20% of her Energy Recharge rate.

  • At Ascension Phase 4, Mona receives 23.2% Hydro DMG Bonus by default, due to her ascension stat of Energy Recharge. An extra 1.6% Hydro DMG Bonus is obtained at Ascension Phases 5 and 6, for a total of 24.8% and 26.4%, respectively.
  • The effects of this passive talent do not show if Mona is fallen or not in the party.
  • In accordance with the established interaction between percentage-based stat conferrals, Waterborne Destiny does not use any points of Energy Recharge that were given to Mona as a percentage of someone else's Energy Recharge, such as from any character wielding Xiphos' Moonlight.

Notes

  1. 1.0 1.1 Mona's real name has been inconsistent in-game, being written as Astrologist Mona Megistus; Mona Megistus, the Astrologist; and Mona Megistus the Astrologist. Regardless, "Astrologist" is part of her name as demonstrated by the fact that the Chinese name includes 阿斯托洛吉斯 Āsītuōluòjísī, the phonetic transcription of "Astrologist" into Chinese instead of the translation 占星术士 Zhānxīng Shùshì, "astrologist."
