Stygian Onslaught is a permanent endgame combat challenge in Genshin Impact. Located in Sal Terrae, Liyue, it tasks players with conquering powerful bosses across three battlefields, requiring multiple prepared teams to maximize rewards. Introduced in Version 5.7, its standout feature is the \"Dust of Enlightenment,\" a special item that allows for artifact substat redistribution, adding a new layer of customization and a social\/co-op dimension to progression. Participants can also earn Primogems, character\/weapon materials, and other valuable rewards.<\/p>\n\n\n\n

While in this state, the Nemesis's Agglomeration Energy is constantly consumed. Dealing Pyro or Electro DMG<\/strong> to the Nemesis drains this energy more quickly. When its Agglomeration Energy is fully depleted, the Nemesis unleashes Sporebloom and switches to the Split State.<\/p>\n\n\n\nSplit State<\/strong><\/p>\n\n\n\nWhen this Nemesis enters the Split State, it splits into a large number of spores. When these spores take damage, a certain percentage of the total damage is also dealt to the Nemesis. After remaining in the Split State for a period of time, the Nemesis will return to the Agglomerated State. In this case, if the number of spores on the field falls below a certain number, the Nemesis will enter the Brittle Agglomerated State, during which all RES is greatly reduced <\/strong>and its combat abilities are diminished. Additionally, if all spores generated in Split State are defeated, the Nemesis will exit the Split State early and go into the Brittle Agglomerated State instead.<\/p>\n\n\n\nHollow Structure<\/strong><\/p>\n\n\n\nAffected by the Ley Line disturbance, when this Nemesis is in the Split State or the Brittle Agglomerated State, its Anemo RES is greatly reduced<\/strong>.<\/p>\n\n\n\nTeam Comps<\/strong><\/p>\n\n\n\n![\"\"](\"https:\/\/www.memuplay.com\/blog\/wp-content\/uploads\/2026\/03\/QQ\u56fe\u724720260303173054.jpg\")
