I genuinely do not know how this Stygian can be possible without Ineffa, Bina, or Varesa. I get that Hoyo likes their shill bosses, and I'm ok with there being one or even two of them, but literally all three were shill bosses. I even have a couple of C6 units and I still almost couldn't clear Fearless. It's a bit much.
