The moment I entered the Stygian Onslaught arena, my palms turned slicker than an eel in olive oil, heart hammering like a blacksmith’s anvil at midnight. This 2025 event isn't just about snagging Primogems or Dust of Enlightenment—it’s a brutal gauntlet where Teyvat’s mightiest bosses morph into sadistic puzzle masters. I’ve faced Abyss floors that felt like gentle strolls, but these five escalating stages (Normal, Advancing, Hard, Menacing, Fearless) plus the bonus Dire level? They’re designed to crush your spirit like a walnut under a steamroller. And oh, the agony of realizing Menacing and above force you to rotate entire teams—no cheesing with your overpowered C6 Hu Tao here! Every second dripped with tension, every boss mechanic a fresh horror. But that Hydro Tulpa? Fighting it felt like trying to bail out a sinking ship with a teaspoon while sharks circled. Let me recount my descent into madness...
Battlefield 1: Hydro Tulpa’s Liquid Lunacy
That watery monstrosity isn’t just a boss—it’s a hydration-obsessed tyrant. Half-Tulpas spawn like gremlins at a rain dance, and if it slurps one up? Healing galore, turning my DPS into damp confetti. Freeze reactions became my lifeline; watching it solidify was more satisfying than popping bubble wrap for hours. But Fearless mode? Pure evil. When that Ward shield emerges, you’ve got nanoseconds to nuke it or kiss your active character goodbye—instant deletion, no rez. I swear, failing felt like watching my dreams dissolve like sugar in a tsunami. My top squads:
-
🔥 Pyro Team: Melt it into steam (Yoimiya + Xiangling = fireworks of fury)
-
🌱 Bloom Crew: Dendro + Hydro chaos (Nahida & Kokomi’s garden of pain)
-
⚡ Hyperbloom Brigade: Electro-charged veggies (Raiden + Alhaitham shredding)
Personal take? This boss’s healing mechanics are sneakier than a pickpocket at a carnival—one misstep and your progress evaporates like morning dew.
Battlefield 2: Lava Dragon’s Fiery Mood Swings
This two-form lava lizard’s RES shifts make it moodier than a cat in a bathtub. First phase? All-element resistance higher than a Sumeru scholar’s ego—only Pyro assaults coax it into phase two, where RES plummets like a stone... except against Pyro itself. But dare touch Hydro or Cryo? It reverts faster than a regretful text message. Fearless amplifies the agony: needing triple the Pyro hits to shift forms felt like trying to light a bonfire with soggy matches. My squads:
| Team Type | Core Characters | Viability |
|---|---|---|
| Pyro Powerhouse | Hu Tao, Bennett, Kazuha | ★★★★★ |
| Burning Madness | Dehya + Nahida | ★★★★☆ |
| Overloaded Orchestra | Klee + Fischl | ★★★☆☆ |
Hydro/Cryo comps? Technically possible if you nuke it fast, but one mistimed skill and it’s like trying to extinguish a volcano with a squirt gun.
Battlefield 3: Automaton’s Robotic Riddles
This mechanical menace offers two paths: Cryo to drain its Flow Momentum (stunning it while shredding RES) or Nightsoul’s Blessing for a risky Counterstrike (RES down but brutal retaliation). Fearless? A nightmare—Cryo barely dents momentum, and Counterstrike hits like a freight train. Timing this felt as precise as defusing a bomb with oven mitts. My strategy? Cryo teams with Ayaka/Ganyu for control, or Yelan with Nightsoul for daring bursts.
The Dire Gauntlet: Where Dreams Go to Die
Dire mode is where F2P souls shatter. Each stage gives you 120 seconds to obliterate tanky bosses—demanding C3R3+ investments. Completing all three in 180s total? A whale’s playground for C6R5 flexers. I tried with my modest C1 units; it was like attacking a bank vault with a spaghetti noodle. The saving grace? Weapon skins aren’t permanent, so F2P folks won’t miss out. Still, witnessing whales conquer it felt like watching gods play chess with meteors.
Final Musings
This event left me exhilarated yet haunted. Is locking peak challenges behind constellations fair, or does it create legends worth chasing? Like a moth to flame, we’re drawn to these brutal trials—but when the screen flashes 'Victory,' it’s sweeter than the last dumpling in Liyue. Yet I wonder... does triumph taste as sweet when paywalls hold the recipe?
