This is my hardest Stygian Onslaught run so far — clearing Version 6.3 on Fearless difficulty against Level 105 bosses, without owning a true Lunar DPS and with plenty of rotation mistakes along the way.

Here’s what I learned from this brutal endgame challenge:

1) Whisperer of Nightmare

This boss has insanely high HP and shield, and even its summoned minions are tanky. Using Lunar reactions is the most effective way to break its shield. Make sure your Lunar DPS and Sub-DPS are built with Crit Rate / Crit DMG to maximize Lunar damage. Once the shield is broken, the boss takes massive damage and RES reduction.

I used a Columbina Lunar-Hyperbloom team:
C0R1 Columbina, C0 Lauma, C1 Nahida, C6 Kuki Shinobu
If you have a real Lunar DPS like Nefer or Flins, the fight becomes much easier. Bigger Lunar damage = faster shield break.
Another option is clearing the summoned mobs using Crowd Control (Kazuha) and nuking everything together. A recommended comp could be:
Mavuika / Arlecchino, Kazuha, Citlali or Bennett, Xilonen.
If even one mob misses Kazuha’s grouping, the rotation can fail.

2) Fireblade Shock Trooper

This boss constantly regenerates an Electro shield, so you must bring reactions that can break it:
Electro-Charged / Lunar-Charged, Overload, or Freeze (3 Cryo).
Electro-Charged and Lunar-Charged are the most consistent options, especially if you own Ineffa or Flins. Freeze teams are much harder and usually require triple Cryo (Skirk, Shenhe, Escoffier). Breaking the shield deals huge damage to the boss.

My team:
C0R1 Arlecchino, C0 Ineffa, C1 Aino, C1R1 Yelan
This comp can trigger Lunar-Charged, Overload, and Vaporize, making it very flexible.

3) Emperor of Fire and Iron

This is one of the hardest bosses on Fearless. It spawns small crab enemies with high HP and shields, and even after breaking its shield, the boss recovers quickly.
You’re highly recommended to use Hydro AoE DPS like Neuvillette. Clearing the crabs deals massive damage to the boss, but they often spread far apart.

My team:
C0 Neuvillette, C0R1 Furina, C0 Escoffier, C3 Mona

I struggled a lot with rotations, got exhausted after many retries, and still managed to clear everything on Android mobile. This run shows that even with skill issues and limited characters, persistence and smart team building can beat the hardest endgame content.
