Genshin Impact update 5.7 rolled out a new permanent endgame mode called Stygian Onslaught today, finally answering the community's requests for a hardcore combat activity other than Spiral Abyss after nearly five years. But as expected, the monkey's paw curls: this thing is so hard that only accounts with substantial character investment can totally clear it.
Stygian Onslaught is essentially a boss rush mode where you use three teams of four units, with no overlap between them, to fight souped-up versions of bosses. For the first Stygian rotation, those bosses are the Hydro Tulpa, Lava Dragon Statue, and Secret Source Automaton. The mode doubles as a special, secondary domain for every type of artifact, dishing out extra artifacts at set Resin intervals, so it's definitely worth doing.
