Mona Megistus, the enigmatic astrologist of Mondstadt, stands as one of Genshin Impact's most unique and powerful support characters. A Mona build, when optimized, unlocks her immense potential to amplify team damage dramatically through her signature ability, the Omen debuff. This guide delves into the intricacies of constructing an effective Mona, exploring her roles as a burst support, hydro enabler, and occasional main damage dealer. Her versatility stems from a kit that blends potent hydro application, significant damage buffs, and unparalleled mobility, making her a cornerstone in many top-tier team compositions.

Her effectiveness hinges on two key abilities. Her Elemental Skill, Mirror Reflection of Doom, summons a Phantom that taunts enemies and applies Hydro periodically, making it an excellent tool for setting up elemental reactions. However, her true power is unlocked with her Elemental Burst, Stellaris Phantasm. This ability traps enemies in an illusory bubble, applying the Wet status. When the bubble pops, it deals substantial AoE Hydro damage. Crucially, it applies the "Omen" debuff, which increases the damage enemies receive. The duration of this Omen is variable; it lasts longer if the bubble is popped via a damage trigger before its natural duration ends, a nuance critical for maximizing her support value. Her Alternate Sprint, Illusory Torrent, provides exceptional mobility and applies Hydro upon emergence, a useful tool for exploration and quick elemental setups.

Weapon choice for Mona is pivotal and varies significantly based on her intended role. For a pure burst support focused on maximizing her utility and team damage amplification, weapons with Energy Recharge or team-buffing capabilities are paramount. The 5-star "Skyward Atlas" provides a high base attack and an elemental damage bonus, solid for a sub-DPS build. However, the 4-star "The Widsith" is often considered her best-in-slot for burst damage, offering a massive temporary buff to either ATK%, Elemental DMG%, or Elemental Mastery upon taking the field. For support, "Thrilling Tales of Dragon Slayers," a 3-star catalyst, is an incredibly accessible and powerful option, granting a massive ATK boost to the next character switched in. The 5-star "Everlasting Moonglow" is niche, better suited for a main DPS or healing-focused build, while "Favonius Codex" helps ensure her burst is always ready by generating energy particles.

The artifact debate for Mona primarily centers on two sets: the Heart of Depth and Noblesse Oblige. A 4-piece Noblesse Oblige set is the classic support choice, boosting the damage of her Stellaris Phantasm and providing a valuable 20% ATK bonus to the entire team for 12 seconds after using her burst. This synergizes perfectly with her role as a damage amplifier. Conversely, a 4-piece Heart of Depth set enhances her Hydro DMG and boosts the damage of her Normal and Charged Attacks after using her Skill, making it the preferred choice for a main DPS or on-field Vaporize Mona. A popular and highly effective hybrid approach is the 2-piece Heart of Depth combined with a 2-piece Noblesse Oblige, offering a balanced increase to both her Hydro DMG and her Burst damage. For main stats, an Energy Recharge or ATK% Sands, a Hydro DMG Bonus Goblet, and a CRIT Rate or CRIT DMG Circlet are standard. Ensuring sufficient Energy Recharge (often 180-220%) to maintain burst uptime is more critical than stacking raw ATK in a support role.

Mona's true genius is realized in specific team compositions, most famously in "Morgana" and its variants. The classic Morgana team consists of Ganyu (Main DPS), Mona (Hydro applicator and buffer), Venti (crowd control and energy generation), and Diona (healer and Cryo resonance). This team utilizes Freeze reactions to keep enemies immobilized, allowing Ganyu's charged shots and Mona's Omen to work on perpetually vulnerable targets. She is also the premier enabler for massive Vaporize nuke compositions. A team like Mona, Bennett (for ATK buff and Pyro application), Sucrose (for Elemental Mastery share and Viridescent Venerer resistance shred), and a Pyro DPS like Diluc or Hu Tao can trigger a devastating Vaporize reaction on her burst. In this sequence, Mona applies Hydro, Sucrose swirls, Bennett uses his burst, and then Mona's burst is triggered, popping the bubble with a Pyro attack to maximize the Omen duration and Vaporize multiplier.

Talent priority reinforces her build focus. For a burst support, leveling her Elemental Burst is the absolute highest priority, as it directly increases the burst's damage and, more importantly, the damage bonus provided by the Omen debuff. Her Elemental Skill can be leveled secondarily for additional damage and better energy generation. Her Normal Attack talent is typically left unleveled unless she is being built as a main DPS. Her constellations provide significant power spikes. C1 extends the duration of the Omen debuff when triggering Vaporize, Electro-Charged, or Frozen reactions, a massive boost. C4 provides a 15% CRIT Rate increase against enemies affected by her Omen for all party members, further cementing her role as a universal buffer. While powerful at C0, these constellations transform her into an even more formidable force.

Mastering a Mona build is about understanding the flow of battle and her place within it. She is not a straightforward damage dealer but a tactical enabler whose value is measured by the exponential increase in her team's output. Whether enabling perpetual Freeze, setting up a cinematic one-shot Vaporize, or simply providing consistent Hydro application and damage amplification, a well-built Mona is a testament to strategic team-building. Investing in her artifacts, understanding her burst mechanics, and slotting her into synergistic teams unlocks one of the game's most rewarding and powerful support experiences, proving that the astrologist's true power lies not in dealing the final blow, but in orchestrating the conditions for victory.
