Stygian Onslaught Luna 5 Best Characters and Boss Advice
Stygian Onslaught is the hardest endgame content available in Genshin Impact facing against 3 different bosses with harder mechanics. Stygian Onslaught proves to be a challenge for all types of players. Here you can see an overview of the boss mechanics, some general combat advice as well as our recommended team compositions to clear Stygian Onslaught in version Luna 5.
But first, some general gameplay advice.
Co-Op Is Your Friend!
Stygian Onslaught can be cleared in Co-Op to an extent with some limitations. Difficulty 1/2/3 support matchmaking-based Co-Op allowing you to farm artifacts easily at Hard III difficulty while still being able to build up Dire Prestige.
Difficulties above that however require you to Co-Op with people inside your world. Furthermore, Fearless V and Dire VI's rewards are solo only. But you can therefore still gain the Dust of Enlightenment from Menacing IV.
Make Sure to Use Exalted Ones
2 Hours after each phases reset, Exalted Ones become available. These are the 16 characters based on the entire server's completion of Dire VI and grants a buff to your characters too. Providing increases to ATK, DEF and HP if you own that character. Exalted Ones do not give you access to that character!
Exalted ones can change daily too so if a character you own is not currently listed, they may change tomorrow.
