Mona's Arsenal Unleashed: Hydro Dominance in Teyvat
When the stars align in Genshin Impact, there's no better celestial conductor than Mona Megistus to orchestrate elemental chaos. Her hydro application isn't just good - it's chef's kiss perfection for triggering those sweet vaporize and freeze reactions. But let's be real, even the mightiest astrologist needs proper tools to flex her true potential. Here's the 2025 breakdown of weapons that'll make Mona go from "meh" to Mona Lisa of destruction! 💧✨
8️⃣ Magic Guide: Budget Beast Mode
Don't sleep on this 3-star gem! The 
Magic Guide turns Mona into an EM (Elemental Mastery) machine. When I first tried R5 version, my vaporize damage went 🚀 to the moon! Perfect for newbies who keep getting this catalyst from every wish (we've all been there).

Pro Tip: Pair with Fischl for constant electro-charged fireworks!

Cons: Looks like a library reject compared to 5-star bling
7️⃣ Wine & Song: Sprinting in Style
The 
Wine and Song makes Mona's signature phantom sprint feel like driving a hydro-powered Lambo. That 40% ATK boost after dashing? Chef's kiss for hit-and-run tactics. Plus, you'll never run out of stamina chasing those pesky Whopperflowers!

6️⃣ Mappa Mare: F2P's Best Friend
Craftable 4-star 
Mappa Mare slaps harder than Zhongli's meteor when you stack elemental reactions. My Ayaka freeze team became literally unthawable with this setup. The EM boost? Magnifique!
5️⃣ Solar Pearl: Crit Machine
This BP-exclusive 
Solar Pearl turns Mona into a crit monster. When I tested it with her C1, the numbers made my eyes water 😭. Perfect for players who want Mona to occasionally main DPS while looking fabulous.
4️⃣ Oathsworn Eye: ER Queen
Event-exclusive 
Oathsworn Eye makes Mona's burst available EVERY. SINGLE. ROTATION. The ATK scaling with ER? Big brain move from Hoyoverse. My spiral abyss clear time improved by 20% using this bad boy.
3️⃣ Favonius Codex: Energy Galore
The 
Favonius Codex is like chugging 5 Red Bulls - Mona's burst gets charged faster than you can say "Astrologist, Mona Megistus!" That sweet 45.9% ER substat? No cap, it's cracked for support builds.
2️⃣ The Widsith: RNGesus' Gift
This Widsith is pure dopamine. When that 480 EM buff hits? Oh lawd the vaporize numbers! But let's be real - getting Recitative when you need Aria feels like getting socks for Christmas 🧦. Still OP though!
1️⃣ Skyward Atlas: Flex on 'Em
The 
Skyward Atlas is Mona's endgame flex. That cloud effect? Literally raining pain from above ☁️💦. When I paired this with 4-piece Heart of Depth, even Azhdaha started sweating (do dragons sweat?).
Final Verdict
At the end of the day, building Mona is like reading constellations - you need the right tools to decipher her true power. Whether you're F2P or a whale, there's always a weapon that'll make her shout "The stars never lie!" while deleting enemy health bars. Remember folks, a well-built Mona isn't just a character - she's a walking hydro apocalypse! 🔮💦
